Prompt Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows the amino acid sequence differences between different organisms for a protein keratin. Changes in amino acid sequences are known to cause changes in structure of proteins. Part A. Consider species A, D, and E. Using the data provided, describe how the structures of their keratin proteins would compare. Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B, A and C, and B and C. Explain how amino acid sequences can be used in determining how closely related two species are. Part C. Based on this data, predict which two species would be more closely related to one another. Part D. Justify your predictions to part C.

Answer:

not all living things move

Explanation:

Animals which are living things have the ability to move as well as microrganisms however, plants and certain microrganisms do not have these abilities and yet are still living.

Answer:

Technically, all living things move in some way.

Different animals, like humans, dogs, and goats, can walk and run. Marine animals can swim and dive. Birds and some insects can fly around.

Plants can move, just not the same way animals can. For example, a sunflower will turn to face towards the sun. Although, plants don't have the ability to move from one place to another, or locomotion.

So, movement can be considered a characteristic of life, but locomotion is not. Plants and other living organisms cannot get up and move from one spot to another spot.

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.

Hope this helps!

Answer:

Its a necessity for all living things

Explanation:

Answer: Diatoms have a cell wall that includes silica, while dinoflagellates have a cell wall that includes cellulose.

Explanation:

Diatoms are unicellular algae. Some of them can live in colonies forming filaments or ribbons, they are surrounded by a cell wall made of silica called a frustula.

They are microscopic animals, almost always single-celled. They have flagella. They can be divided into two large groups differentiated by the presence or absence of cellulosic plaques in the cell wall or amphysm.

Answer:

B. Lipids

Explanation:

Glycoconjugates occurs as a result of a process known as glycosylation.

Glycoconjugates result from the covalent linkage of carbohydrate to proteins or lipids.

It is also used to refer to carbohydrates who are covalently bonded to other chemical compounds such as protein, lipids, peptides etc.

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.

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:

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.

Answer:

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured. :)

Answer:

e. all of the above.

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 and Explanation:

1. Hypothesis: The more sunflower seeds the students get, the better they will do on a quiz.

2. Dependent Variable: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.

3. Independent Variable: number of sunflower seeds. Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.

4. Constant Control Group: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment

5. Experimental Group: Groups 2 and 3, that received different amounts of seeds.

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.

Answer:

B- The speed of sound will increase due to the increasing density of seawater.

Explanation:

If the temperature of seawater decreases its density increases, but only to a point

Answer:

C. The speed of sound will decrease due to the increasing density of seawater. Most likely to occur if the temperature of seawater decreases.

Explanation:

Most likely to occur if the temperature of seawater decreases.

Answer:

B. Begin dividing and growing larger.

Explanation:

When the sperm and egg cells fuse during fertilization they form a zygote. The zygote then starts to begin to divide rapidly and start growing larger and bigger.

After this process the cells then begin to become differentiated and the parts of the body now become more visible and pronounced.

Answer: Option A.

The types of solutes and their distribution between the ICF and ECF are not the same

Explanation:

Intracellular fluids are fluids found inside the cell's cytoplasm while extracellular fluid are fluids the flow outside the cells which consist of plasma, interstitial and trancellular fluid

The types of solutes and their distribution between the ICF and ECF are not the same because intracellular fluid of the cystosol is composed of water, dissolved ions, small molecules, and large, water-soluble molecules while extracellular fluid consist of plasma, interstitial fluid and cytosol have high potassium concentration and low sodium Concentration.

The given case could progress into all the outcomes except intraspecific competition

Intraspecific interaction is a kind of interaction seen within the same species that compete for basic necessities for survival such as food, habitat, and water. It does not lead to evolutionary changes within the species, therefore they do not develop adaptations in response to the competition

Thus, it can be concluded that the adaptation in direct response to one another could lead to all except intraspecific interaction
