Answer:
1. 128
2. 16,384
Explanation:
Imagine there were two pairs of chromosomes:
A paired with B
C paired with D
A gamete could have the following combinations:
A + C
A + D
B + C
B + D
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
With seven pairs of chromosomes, there are (2⁷) possibilities. 2⁷ = 128
For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
Answer:
C. parvum takes energy from glucose which is present in the digestive tract after the process of glycolysis.
Lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate molecule.
Explanation:
C. parvum is a protozoa that lives as a parasite in the digestive tract of animals. They take nutrients from the cell which are present in the form of glucose. C. parvum uses a specific type of enzyme i. e. lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate and also helps in the production of ATP through glycolysis process. In this process, the glucose molecule is broken down into two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. So C. parvum takes ATP from that way from the host cells.
Answer:
mitosis
Explanation:
The cellular process that enables the cells to grow and develop into tissue is mitosis.
Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.
<em>Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by </em><em>mitosis</em><em> so as to replace the damaged cells due to the injury. By doing so, the injured area heals.</em>
A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. so must be option D
