Answer:

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.

If a lock and key fit perfectly together and then one day the key melts and then it is now more droopy and no longer can fit into the lock, then that key wont work for the lock anymore. It's the same as if an enzyme breaks down a bit and now the shape doesn't fit perfectly, the enzyme doesn't work anymore

Explanation:

A TVET qualification is easier to achieve and at a lower price also focused on getting you into the workforce faster. University is geared towards the transfer of knowledge rather than skills.

the stigma associated with TVET colleges are that those who go to the college is a failure. or a institute for those who aren't smart enough. And also for those who failed to get into university

The difference between a university and a TVET college in terms of what each offers is university impact knowledge while TVET college is more of practical.

The difference is University provide students with the knowledge they need based on the course they are studying while TVET colleges is more of practical.

The stigma associated with TVET colleges​ is because people think that University student has higher opportunities when they are in the labor market than TVET colleges student.

Inconclusion the difference between a university and a TVET college in terms of what each offers is university impact knowledge while TVET college is more of practical.

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.

Explanation:

Antibiotics are added to the animal feed or drinking water of cattle, hogs, poultry and other food-producing animals to help them gain weight faster or use less food to gain weight.

Because all uses of antimicrobial drugs, animals contribute to the development of antimicrobial resistance, it is important to use these drugs only when medically necessary.

the production (e.g. growth enhancement) purposes as well as for the treatment, control or prevention of animal diseases. Even today, it is not entirely understood how these drugs make animals grow faster. The drugs are primarily added to feed, although they are sometimes added to the animals’ drinking water.

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.

organs in each organ system all work together to perform a particular task.

the organs are arranged into 11 organs systems but 4 for example are the skeletal system, respiratory system, digestive system and nervous system.

hope this helps!!!

The organs are systematically arranged into organ systems in order to perform a specific task. They work on the principle of teamwork whose task is equally distributed among the various organs in order to synthesize an organ system.

An organ system may be defined as a biological system comprising a cluster of organs that significantly work together in order to perform one or more specific functions.

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.

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.
