ANSWER AND EXPLAIN PLZ:)

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.

Answer:

The correct answer is B. ribosomes.

Explanation:

Prokaryotic cells, like bacteria, are cells that do not have any organelles.  Unlike eukaryotic cells, they do not have a nucleus or other membrane-bound structures inside their cell membrane.  Therefore, prokaryotic cells do not have chloroplasts, mitochondria, or nuclei, but they do have ribosomes (as do eukaryotic cells) which are an important component of protein production in the cell.

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.

Explanation:

Acetyl-CoA is a biochemical agent, in which its main function is to transport acetyl group to the citric acid cycle. It works in metabolic reactions of protein, carbohydrate, and lipid

Acetyl-CoA is transported through the mitochondrial membrane, and enters the cytoplasm of the cell, as the molecule citrate.

The shuttle system for transfer of acetyl-CoA generated in the mitochondrial matrix to the cytosol includes:

1. citrate from the citric acid cycle.

2. citrate lyase in the cytosol.

3. ATP hydrolysis.

4. the production of NADPH by malic enzyme.

Hence, the right answer is option E: All of the above.

Answer:

B= inorganic

Explanation:

inorganic means not organic

Inorganic means that has never been living, the correct option is B.

Organic and inorganic compounds are the building blocks of chemistry. The main distinction among both organic and inorganic compounds is that organic compounds every time contain carbon, whereas most inorganic compounds do not.

Furthermore, almost all organic compounds encompass carbon-hydrogen or C-H bonds.

In other statements, inorganic refers to not being made up of or derived from living matter.

A living organism is made up of cells. The cells differentiate, and the organisms' bodies grow as the number of cells increases. A tree is a living organism that exhibits the growth process.

Thus, the correct option is B, as inorganic implies to the one that is not living.

Answer:

b thrombin

Explanation:

thrombin catalyzes the activation of the molecules that are present in plasma

The protein thrombin involved in coagulation provides the activation for the final step in clotting. Thus, the correct option is B.

Clotting may be defined as the procedure in which blood alters into a solid state to construct a thick mass or lump onto the surface of the injured region.

The protein thrombin catalyzes the final step in clotting which transforms fibrinogen into fibrin. Then such fibrin monomers polymerize and construct a mess of fibrin polymers which results in a fibrin clot.

Therefore, the correct option for this question is B.

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.

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.

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.

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.
