Answer:The leaf is the main lateral organ of the green plant that is responsible for photosynthesis.in plants that resides in forest floors,they rarely get sunlight as they are under the canopy of the taller trees,their leafs have broad flattened blade to ensure a large surface area of chloroplast in order to capture any light that may pass through the canopy .they also possesses thin lamina

plants that grow in hot and dried environment have to conserve and store water,their leaves are thin and thick and possesses parenchymatous cells that helps to store water in large vacuoles.

The epidermis is impregnated with cutin ,the stomata are present on the lower epidermis.they usually keep their stomata closed during the day to prevent water loss

Match each scenario to its related biomolecules. Jack is eating a diet that will help him build muscle, so he eats a diet high i
Stells [14]

The options for this question are as follows:

A. Nucleic acids

B. Carbohydrates

C. Fats

D. Proteins

Now the correct answers of the match are as follows:

Jack is eating a diet that will help him build muscle, so he eats a diet high in this. <u>D. Proteins</u>

Explanation: Proteins help to build up the muscles. That's why people who want to do body-building, eat protein rich foods, like chicken, eggs, soy, etc.

Before a race, Ruth drinks a beverage full of this biomolecule to get energy. <u>B. Carbohydrate </u>

Explanation: This biomolecule provides instant energy to our body. For example, glucose is consumed before race, as dissolves quickly in our blood and provides instant energy. Glucose is an example of simplest carbohydrate.

These molecules in olive oil will help Ruth’s body store long-term energy. <u>C. Fats </u>

Explanation: Fats are the kind of biomolecule which is stored in our body in the adipose tissues. Also, when glucose is all used up by our body cells, the body starts to get energy from this stored fat.

Elizabeth has been advised to go for genetic screening to detect any abnormalities in her unborn child. <u>A. Nucleic acids </u>

Explanation: Every cell of our body has DNA, and it contains all the genetic information about the whole body. DNA is a kind of nucleic acid. If Elizabeth is going for test of the abnormality, it means she is going to test for the DNA of her child.

1. Which of the following molecules is broken down in cellular respiration, providing fuel for the cell?
vladimir1956 [14]
1. Cellular respiration is a metabolic pathway that occurs inside the cell. During cellular respiration, glucose molecule is broken down in the presence of oxygen.

2. During cellular respiration, ATP (Adenosine Triphosphate) molecule is also produced that acts as energy currency and directly powers cell work.

3. Amylase is an enzyme that helps in digestion. It catalyzes the hydrolysis of starch into simple sugars. If amylase is present in normal amount it will break down starch into disaccharides. If the amount of disaccharidase amount is less than usual then less disaccharides will be broken down into monosaccharides. Thus the production of monosaccharides will decrease.

4. In the reactions shown above, the end product is largely dependent on the last enzyme. If Enzyme3 is in less amount than usual then there will be greatest reduction in the production of G and H. This is because the formation of product in any reaction is dependent on the substrate concentration and enzyme concentration.
