Several students were having a discussion about the role of chromosomes in inheriting traits.
serious [3.7K]

Answer:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.

Explanation:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.

Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait.  - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes

Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.  - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.

Why does the mass of a substance remain the same after a chemical reaction
11111nata11111 [884]

Answer:

Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.
