Answer:

The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

Answer:

You answer is B

Explanation:

This is the only possible answer because when animals die they might get trapped under layers of bone conserving the bone, and B is the answer because if bones are conserved in the sediment Scientists may be able to recognize certain animals for example, 1000 years ago a cow dies and is buried by sediment, the skeleton remains allowing scientists in the present year to analyze it, they might notice slight changes in things like the bones, or the teeth, etcetera, thus this is how Scientists found proof of evolution.

Diagram of simple cuboidal epithelium. By lining the surface of various ducts of various glands and organs, simple cuboidal cells are able to provide a layer of protection from abrasion, foreign particles, invading bacteria and excessive water loss (due to its selective permeability) to the underlying tissue.

Explanation:

Answer:

Simple cuboidal epithelium consists of a single layer cells that are as tall as they are wide. The important functions of the simple cuboidal epithelium are secretion and absorption. This epithelial type is found in the small collecting ducts of the kidneys, pancreas, and salivary glands.

In order to survive.

Explanation:

A normally aquatic species adapt to the supralittoral fringe in order to survive in that environment. Supralittoral zone also referred to the area on coastlines and estuaries, that is regularly splashed, but not submerged by ocean water. This environment is different for the marine organisms that causes adverse effect on the marine organisms but these marine animals has the ability to adapt that environment by using certain mechanism in order to survive and easily reproduce in that environment.

Answer:

1. Histone methylation occurs at different amino acids: c. Activates and inactivates

2. A transcriptional binds an enhancer sequence: d. No effect

3. Histone acetyltransferase attach acetyl groups to the N-terminus of histones: a. Activates

4. Histone deacetylases remove acetyl groups from the N-terminus of histones: b. Inactivates

Explanation:

Epigenetics refers to the mechanisms associated with changes in gene expression which do no involve alteration in DNA sequence. Epigenetic marks include DNA methylation and histone modifications (acetylation, methylation, phosphorylation, etc). These mechanisms act together in order to regulate gene expression at specific genomic sites (loci). Histone methylation is an epigenetic mark involved both in transcriptional repression and transcriptional activation. For example, trimethylation of the histone H3 at lysine 4 (H3K4me3) has been associated with transcriptional activation, while dimethylation of histone H3 at lysine 9 (H3K9me2) is often involved in transcriptional repression. Moreover, histone acetylation by histone acetyltransferases (HATs) is an epigenetic mark that is involved in transcriptional activation and chromatin decondensation, while histone deacetylation by deacetylases (HDACs ) is generally associated with gene repression. However, it is important to highlight that there are exceptions to this rule (for example, acetylation of the histone H4 lysine 20 is associated with gene repression). Finally, transcriptional activators are proteins that bind to enhancers in order to recruit coactivator proteins/complexes and thus activate transcription.

Water is a renewable earth resource that is essential for life. Limiting the use of acids and pollutants is a positive way of affecting water.

Water pollution is the contamination of water resources by the addition of pollutants that alters the quality of the water. Many human activities like farming practices, increased use of fertilizers, chemicals from the factory, etc. are the major reason for water pollution.

If the use of the acids and the other polluting substances is reduced then the pollution of the resources will decrease and will increase the quality of the life hence improving the water ecosystem.

Therefore, option D. limiting the use of acid and other pollutants is a positive way to reduce water pollution.
