Nearly all cells in an organism contain identical dna, and each dna strand may contain hunndreds or thousands of individual genes. is it likely that a cell would transcribe all the genes within its nucleus simultaneously.

a. true
b. false

Nearly all cells in an organism contain identical DNA, and each DNA strand may contain hundreds or thousands of individual genes. It is likely that a cell would transcribe all the genes within its nucleus simultaneously.

A. True

B. False

B. False

Explanation:

All the cells present in the bodies of the multicellular organisms are derived from the zygote and therefore carry identical DNA. However, cells are differentiated to perform specific functions. Also, cells may perform different functions at different times depending upon the need of the body. So, all the genes present in the DNA of a cell are not expressed simultaneously. Cells only express the genes whose protein products are required at that time.

For example, genes required for secretion and release of insulin in the endocrine cells of the pancreas would be expressed only when the blood glucose levels are higher.

explanation:

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
