Animal researchers refer to the process of filtering out sights, scents, and sounds that have little effect on survival asa. aggression.
b. desensitizing.
c. nurturing.
d. habituation.

Answers

Answer 1
Answer: The answer is option D. Habituation. Habituation is the process of filtering out sights, scents, and sounds that have little effect on survival. Habituation is the diminished response of animals to certain stimuli that are deemed unnecessary or irrelevant in the process of of survival.

Do the results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription? Why or why not?Do the results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription? Why or why not?
No, because histone modifications do not affect transcription
No, because the results demonstrate only a correlation between altered histone modifications and reduced transcription
Yes, because the observed changes in histone modifications are consistent with reduced transcription.
Yes, because histone modification is the only regulatory mechanism that could affect transcription

Answers

The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because the observed changes in histone modifications are consistent with reduced transcription.

_____________ take up stations in tissues and act as scavengers, devouring pathogens and worn -out cells.A. Natural killer cells
B. Amino acid cells
C. Enteric cells
D. Macrophages

Answers

D. Macrophages


These cells, unlike Neutrophils, tend to go and settle in a tissue and kill pathogens as well as worn out cells. Natural killer cells are used for something similar - they kill cells that have been infected by a pathogen and are displaying the pathogen's antigen on their surface (antigen presentation) - this is how the Killer-T-cells are able to recognise which cells need to be destroyed.

in human cells 2N = 46. how many chromosomes would you expect to find in a sperm cell? in am egg cell? in a white blood cell? Explain

Answers

Answer:

There will be 23 chromosomes in a sperm cell, 23 chromosomes in an egg cell, and 46 chromosomes in a white blood cell

Explanation:

Human cells are diploid in number i.e they exists in two basic sets (2N =46, where N is 23). So, cells of human body such as blood cells like white blood cells have two basic sets of chromosomes i.e 46 chromosomes, since they are produced by mitosis.

On the other hand, cells of humans involved in sexual reproduction such as the gametes (sperm and egg) have only one set of chromosomes since they are produced by meiosis - so they are haploid (N =23).

Answer:

Sperm=23

Egg cell=23

White blood cell=46

Explanation:

During cell division Meiosis produce haploid number of gametic chromosome 23.

The somatic cell contains 46 chromosome i.e diploid chromosome number. During cell division in meiosis gametes cells contains haploid number-23 chromosome which is half of the somatic cell chromosome.

During conjugation, haploid chromosome is donated by each parent to give a diploid organism with 46 chromosome number.

White blood cell contains 46 chromosome because it doesn't undergo cell division it is a somatic cell.

The cell cycle in prokaryotes includes DNA replication.

How do enzymes help to carry out biochemical reactions?A. By decreasing the energy of the reactants
B. By increasing the activation energy of the reaction
C. By decreasing the activation energy of the reaction
D. By increasing the energy of the products of the reaction
E. By decreasing the energy of the products of the reaction

Answers

The answer is C. Enzymes lower activation energy, allowing the reaction to happen more quickly, which is why they are called catalysts.

Answer:

Enzymes help to carry out biochemical reactions C). By decreasing the activation energy of the reaction

Explanation:

Enzyme catalysis An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
