Which process allows a mammal to continue togrow in size?
(1) mitosis of sex cells
(2) mitosis of body cells
(3) meiosis of sex cells
(4) meiosis of body cells
Answers
Answer: The correct answer is-
(2) mitosis of body cells.
Mitosis is a type of cell division in which a parent cell produces two daughter cells having same number of chromosomes as that of their parent cell.
It occurs through a series of 5 stages that are- Prophase, metaphase, anaphase, telophase, and cytokinesis.
It is responsible for the growth of organisms and the repair of damaged tissues (in case of multicellular organisms) as new, identical cells (that are identical to each other) are produced from the parent cell.
Thus, option 2) is the right answer.

2) mitosis of body cells

d. genetic makeup
Answers
Answer:
Activity level.
Explanation:
Metabolism is the important for the cell survival and its growth. Most of the metabolic factors does not depend upon the control of the organism and occurs itself in the body.
Some factors can be improved or controlled by the activity level. The activity level can be controlled by the individual and may affect the flexibility and may also affect the other metabolic factor. One can control its own activity level.
Thus, the correct answer is option (b).
B. The Y chromosome doesn't experience crossing-over.
C. The mitochondria DNA in a mother and her offspring vary greatly.
D. The X chromosome can only be passed from a father to his son.
Answers
The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.
The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.
Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.

56,320
Answers
Answer: 56,320
Explanation:
Volume of a substance is defined as the quantity of three-dimensional space occupied by a substance. The units used to express volume are liters, cubic meters, gallons, milliliters etc.
By metric based system of units :
1 kilo (k) =
Given: 56.32 kL of volume of a substance
Thus as 1kL is equal to 1000 L
56.32 kL is equal to =
Thus the volume in Liters will be 56320.
