5 0

Answer:

4

Explanation:

Producers are at the bottom of the energy pyramid because they prove the most energy, they make up most of the population, which is biomass. And the producers have the largest population, which is why they are at the bottom of the pyramid of numbers. Finally they are at the bottom of food chains and webs because they store the most energy inside of them.

Consider the parts of the digestive system, particularly the place where water is removed before feces are excreted. Which organ
Phoenix [80]

Answer:

The colon.

Explanation:

The colon, also known as the large intestine is one of the major organs of the digestive system and plays a vital role in the processing of food and excretion of waste. It is divided into the ascending colon, transverse colon, descending colon and sigmoid colon.

The colon has a large surface area and plays a major role in the reabsorption of fluids and the processing and formation of waste which it pushes towards the rectum to be expelled.

Diarrhea is a condition which is characterized by frequency of bowel movements and passage of loose and watery stools. It has various causes most of which affects the normal functionality of the colon thereby limiting it's ability to reabsorb water and fluids. Such causes which affect the colon include; Bacterial infections, laxative abuse, diseases of the colon such as ulcerative colitis and Crohn's disease etc.

g A mutation occurs upstream of gene A in the region encoding the ribosome binding site, making it bind more weakly to the ribos
Ivanshal [37]

Answer:

it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A

Explanation:

Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.

An example of an epigenetic change is
Oksana_A [137]

Answer:

The correct answer is option d.

Explanation:

An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.  

One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.  

In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.

Explain why identifying
inna [77]

Answer:

<u><em>It is because humans have much larger genomes than bacteria</em></u>

<u><em /></u>

Explanation:

It is because humans have much larger genomes than bacteria. The largest bacterial genome ; human clocks. But corn is about 3 times that, spruce is twice again that and some plants go even bigger. For example, every one of tulip’s chromosomes is about one human genome in size, and bacteria are haploid, humans are diploid. That makes assembling the DNA fragments much more tricky, as you don’t want to have a final sequence that switches between the two haplotypes.
