4 0

Answer:

A. 1.2

Explanation:

Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.

Most of the human DNA, or human genes, are located in the chromosomes.

Each metaphase chromosome consists of:

two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids;  two centromeres, one on each chromatid.

Changing environmental conditions, such as temperature or PH, can effect enzyme shape how would this alter the enzymes function?
dlinn [17]

Raising the temperature will denature an enzyme so that it is no longer functional. Lowering the temperature will reduce the rate of the reaction so low as to make it seem non-functional. Altering the pH above or below its optimum pH will also reduce the enzyme's activity, and at extremes the enzyme may be permanently denatured.
