Answer:

<em>The correct option is d)  an ecotone</em>

Explanation:

An ecotone can be described as an area of transition between two different biomes. An estuary can be described as an ecotone where the river water meets the seawater. The freshwater biome mixes with the seawater biome in an estuary. Unique plants and animals are grown in an estuary which are adapted to live in such an environment. The water present in an estuary is termed as brackish water. Hence, the correct option is d.

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,  

<u>For sample A </u>

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

<u>For sample B </u>

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,  

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Which does not contribute to triglyceride digestion?
kozerog [31]
The correct answer is lipase activity in the large intestine.
Triglycerides are the main components of body fat and human skin oils. Lipases are enzymes which break down the fats or lipids in the body. They are responsible for the digestion and general processing of triglycerides. There are several different lipases in the human body, pancreatic lipase acting in the small intestine, hepatic lipase, lipase acting in the endothelium and lipase in the bile acid.

Monocot seed vs. dicot seed characteristics ?
mash [69]
Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside theseed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. [Credit to: Monocots and Dicots - The seed site]

Explain the digestion process of a complex carbohydrate by arranging the statements in the order that they occur.
andreyandreev [35.5K]

Answer: The question is incomplete because the options are not given, here are the options from another websites.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides.

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

D.Amylase is deactivated by the low pH in the stomach.

E.. Monosaccharides are absorbed through the intestinal wad.

The correct order are,

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

D.Amylase is deactivated by the low pH in the stomach.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides

.E. Monosaccharides are absorbed through the intestinal wad

Explanation:

Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c

Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.

Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.
