What is true of most body cells except skin cells?
A. While each cell type in the body contains the same kinds of genes, they are organized
on different chromosomes deepening on the cell type.

B. Each body cell contains the same number of chromosomes for that organism. The
chromosomes contain the same number and kinds of genes for that individual.

C. While each cell in the body contains the same number of chromosomes, each cell type
has different genes along those chromosomes.

D. Each cell type carries chromosomes and genes that identify it as that specific type of
cell. For example, skin cells have different chromosomes and genes than muscle cells.

I think the actual question should say "What is true of most body cells except skin cells?" I found this on another source.

B

Explanation:

A is false for all cell types. In every cell, genes are organised into chromosomes in the same way. However, the way they are expressed is different between different cells.

C - is false for all cell types - all cells contain the same chromosomes with the same genes.

D - is false. All cells contain the same chromosomes and genes, it is the expression patterns of the genes that direct cell identity.

B is true, each body cell contains the same genes and chromosomes. The only exception is the sex chromosomes, which are haploid and genetically unique. This means that when fertilisation occurs following sexual reproduction, the diploid state is restored and a genetically unique organism is created.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
