Collagen is the structural protein found in skin and connective tissue. This protein is the most abundant protein, that makes up one-third of the protein in the human body. The function of this protein in the skin is to give the skin strength and elasticity, and to replace dead skin cells. In connective tissues it s<span>upports structures and anchor cells to each other.</span>
Answer: true
Explanation: the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another.
True
Explanation:
The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.
According to Newton's law of universal gravitation:
"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".
Mathematically, the law is written as:
F = 
F is the gravitational force
G is the universal gravitational constant
m is the mass of the body
r is the distances between them.
We see that the less the distance between the two bodies the more the gravitational force they have.

<u>Answer:</u>
As an overall result of the citric acid cycle, NADH atoms are produced.
Option: (B)
<u>Explanation:</u>
- Citric acid cycle or the Tricarboxylic acid cycle is cellular metabolism of plants for the production of energy and bio-synthesis.
- The NADH molecules are produced from the reduction of NAD+ ion in the krebs cycle/citric acid cycle.
- NAD+ molecules can be reduced in 3 stages. During tranformation of isocitrate to α-ketoglutarato, α-ketoglutarato to succinyl CoA, malate to oxaloacetate, one NAD+ ion accepts H+ and forms NADH molecule, thus totally three NADH molecules are produced from NAD+ ions in citric acid cycle.
