Chlorpromazine (Thorazine) may cause which of the following side effects? a. Respiratory depression b. Hemorrhage c. Tachycardia d. Gastric ulcers
Answer:
The correct answer is option d. "Gastric ulcers".
Explanation:
Chlorpromazine (Thorazine) is an antipsychotic medication, the widest medicine used to treat schizophrenia, and other psychotic disorders such as bipolar disorder. One of the most common side effects of the use of Chlorpromazine is the formation of gastric ulcers. This happens because Chlorpromazine inhibits histamine and insulin, two compounds that stimulate gastric secretion.
Explain how and where volcanoes form (how the chemical composition of lava affects the type of volcano formed).
Answer:
Magmas differ in composition, which affects viscosity. Magma composition has a large effect on how a volcano erupts. Felsic lavas are more viscous and erupt explosively or do not erupt. Mafic lavas are less viscous and erupt effusively.
Explanation:
How does blood ph change during exercise?
Answer:
The lungs provide a faster way to help control the pH of the blood. In response to exercise, the body increases its breathing rate which helps to counteract the pH-lowering effects of exercise by removing CO2, a component of the principal pH buffer in the blood.
Classify each statement based on whether it describes prokaryotes only, eukaryotes only, or can describe both prokaryotes and eukaryotes.
1. unicellular
2. contain mitochondria
3. are generally less than 2 pm
4. multicellular
5. lack membrane-bound organelles
Answer:
unicellular - both prokaryotes and eukaryotes
contain mitochondrion - eukaryotes only
are generally less than 2 pm - Prokaryotes only
multicellular - eukaryotes only
lack membrane-bound organelles - prokaryotes only
Explanation:
Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.
Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.
When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.
Decide the outcome of the hypothetical situation by dragging the label into the appropriate category Increase Would tissue damage increase or decrease if the epidermis of the skin was composed of nonkeratinized tissue? Would elasticity of the ears increase or decrease f the elastic cartilage was replaced with bone?
Would texibiliny of the intervertebral dises increase or decrease if the ibrocartlage was replaced with elastic cartilage?
Would diffusion rates of oxygen increase or decrease if the alveolar Ining of the lungs was made of stratified epithelum?

Would the rate of infection increase or decrease i the epidermis was composed of pseudostratifed epithelium?
Would the vascularity of ligaments increase or decrease if they were made of bone?
Would protection of the brain increase or decrease the soงเ was made of hyaline cartilage?
Answer:
Would tissue damage increase or decrease if the epidermis of the skin is composed of non-keratinized tissue? Yes, since keratin is considered to be responsible for confining a little more stiffness to the tissue and structure, would the elasticity of the ears increase or decrease if the elastic cartilage were replaced by bone? It would decrease, elastic cartilage has more elasticity than bone tissue.
Would the texibily and intervertebral diseases increase or decrease if the ibrocartlage were replaced by elastic cartilage? It would decrease.
Would oxygen diffusion rates increase or decrease if the alveolar interior of the lungs were made up of stratified epithelium? They would decrease, since the epithelia have different shapes according to their function, the cylindrical epithelia are those specialized in absorption and exchange of molecular or chemical substances, the stratified ones with abundant stratum corneum function as barriers, either for protection or compartmental such as the epidermis. , therefore, the passage of oxygen will be less when facing the corneal barrier.
Would involuntary control of digestive motility increase or decrease if the intestines contained skeletal muscle? They would decrease, since it would become a voluntary function, and not an involuntary automatic physiological one.
Would the infection rate increase or decrease if the epidermis was composed of pseudostratified epithelium? It would increase, because the epidermis must have the corneal barrier in order to protect our organism and thus hinder the passage of pathogens into the organism, the function of the epidermis is to comply with the highly keratinized barrier of the stratum corneum.
Would the vascularity of the ligaments increase or decrease if they were made of bone? It would decrease or increase depending on the type of bone, since the cancellous is highly vascularized and the laminar one is not. But if we consider that elasticity gives more movement and movement improves circulation and vascularization, so in general terms, this would decrease.
Would brain protection increase or decrease the way ง เ was made of hyaline cartilage? It would decrease, since hyaline cartilage is less resistant and less rigid than bone tissue, thus generating possible compressions of the central nervous system.

Explanation:
what is one disadvantage of insect stridulation
Answer:
Many insects stridulate when they are handled or attacked. It has been suggested that this disturbance stridulation acts to deter predators. This hypothesis was investigated in a series of experiments. Predators were given insects which had been silenced by disruption of their sound-producing mechanism or else had been sham operated but retained their normal ability to stridulate. 2. Three types of insects (mutillid wasps, Dasymutilla spp.; water scavenger beetles, Tropisternus spp.; and round sand beetles, Omophron labiatus) were given to wolf spiders (Lycosa ceratiola and Geolycosa ornatipes) at night in the field under natural conditions. When attacking silenced insects, spiders displayed greater persistence than when attacking phonic insects (Table 1). In addition, mortality was greater among silenced insects. 3. Spiders (L. ceratiola) were also given an artificial 'insect' - a vibrating probe whose vibration mimicked that of the cuticle of a stridulating insect. As with real insects, spiders persisted longer in their attack on the probe when it was silent than when it was 'stridulating.' 4. Female mutillid wasps were given to wild-caught mice (Peromyscus floridanus) in the laboratory. Unsilenced mutillids survived the encounter more often than their silenced counterparts. In another experiment, the stings of mutillid wasps were removed before testing. Mice killed nearly all these 'unprotected' mutillids. However, it took mice significantly longer to attack unsilenced mutillids and longer to kill them after initiating the assault (Table 2). 5. These results support the view that insect disturbance stridulation deters predators. Two modes of action by which these sounds may have their effect are discussed: they may serve to startle the attacker or they may alert it to the potential harmfulness of the insect and as such may qualify as an example of acoustic aposematism.

Angela is curious about how Clomid works to stimulate her ovaries. Her doctor told her that this drug works by "tricking the brain into thinking that the levels of estrogen in the body are low." Which of the following statements help explain why this would lead to a stimulation of the ovaries?
a. Clomid is a drug that inhibits the effect of FSH stimulating follicle development in the ovaries
b. Clomid prevents estrogen from exerting negative feedback, so LH and FSH levels remain high and continue to stimulate the ovaries
c. Clomid produces strong negative feedback on the brain, which leads to a drop in FSH and LH levels.
d. Clomid blocks the effect of FSH on the ovaries. The ovaries respond by increasing their production of estrogen.
Answer:
b. Clomid prevents estrogen from exerting negative feedback, so LH and FSH levels remain high and continue to stimulate the ovaries
Explanation:
Clomifene, also known by its commercial name Clomid, is a drug used to stimulate ovulation, and therefore used in fertility treatment. Clomid is a drug that works on estrogen receptors in order to stimulate the secretion of gonadotrophin by the pituitary gland, and by blocking negative feedback of estrogen steroid hormones (estradiol), thereby increasing the concentration of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). A high FSH concentration leads to the growth of ovarian follicles, whose rupture results in ovulation.

In what ways is eukaryotic replication similar to bacterial replication, and in what ways is it different
Answer:
Ways in which DNA replication is similar in eukaryotes and bacteria:
Replication is semiconservative.
Replication origins serve as starting points for replication.
A short segment of RNA called a primer provides a 3′-OH group for DNA polymerases to begin the synthesis of the new strands.
Synthesis is in the 5′-to-3′ direction.
The template strand is read in the 3′-to-5′ direction.
Deoxyribonucleoside triphosphates are the substrates.
Replication is continuous on the leading strand and discontinuous on the lagging strand.
Ways in which eukaryotic DNA replication differs from bacterial replication:
There are multiple origins of replications per chromosome.
Several different DNA polymerases have different functions.
Immediately after DNA replication, nucleosomes are assembled.

Jasmin left a towel to dry overnigjt,explain why the wet towel was able to dry even though theres no sun
Answer:
When water is warm it evaporates much quicker than when water is cool. Therefore, the heat from the sun helps to dry clothes quickly.
Wind - Another drying factor is the wind. If it is a windy day the water is evaporated more quickly due to the air moving / passing through the clothes.
Try this outside experiment on a windy day and compare your results to doing this experiment on a sunny day.
Be sure to do a fair test using the same items and same method.
So, to sum it up, why do clothes dry in the sun?
Wet clothes dry in sunshine because the water that makes them wet evaporates. This means that the water turns into a gas and becomes part of the air. Evaporation happens more quickly when water is warm, and this is why a warm day is better than a cool day for drying clothes. Evaporation happens more quickly if the air is moving as well - so windy days are good days to help dry your clothes quicker.

Which of the following will increase the gravitational force exerted by one object on another? Increasing the temperature of the objects Decreasing the temperature of the objects Decreasing the distance between the objects Increasing the distance between the objects
The correct answer is C. Decreasing the distance between the objects
Explanation:
Gravitational force and distance between the objects involved are inversely proportional variables; this means gravitation increases when the distance decreases. An example of this is that the Sun's gravitational force strongly attracts objects near it including planets in our Solar system, which causes planets to orbit the Sun. However, the force the Sun exerts on planets in other solar systems or in other galaxies is low due to the distance between this and the sun. In this context, to increase the gravitational force the distance between the objects should be decreased.

what is sex?(explain it )
life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
Answer:
True
Explanation:
The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.
Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells.
Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms. During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

(Darwin's theory)
Most of a cell's molecules can be classified as belonging to one of four major classes: lipids, carbohydrates, nucleotides, or amino acids. Classify the five molecules into one of the four major classes.
Answer:
Diagram, in attachments
Explanation:
From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules attached to it.
The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and Nitrogenous bases.This is the structure of nucleotides and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another nucleotide molecule it forms a nucleic acid molecule.
The second structure from left to right with long carbon chains, it is a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.
However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced one of the the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.
The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids and hyrdogen atom.In the above structure condensation reaction has occurred between the hydrogen atom of the amine group and carbonyl group of the other amino unit to form a dipeptide.The bond formed from the condensation is the peptide bond.
The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO -Carbonyl group and hydroxyl group are glues to this.
