Answer:
Weight in mice is a polygenic trait
Explanation:
Her observation might be as a result of the weight trait being a polygenic trait. A polygenic trait is a trait are train that are controlled by two or more genes. Additive interactions of these genes can influence expression of the trait. Thus weight is expression of a trait influenced by two or more genes. This to knock out the trait, she has to all genes involved in the expression and not just one gene.
Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1).

<span>The two identical daughter cells resulting from
mitosis and cytokinesis are identical in the following ways:1. Mitosis
occurs when the nucleus of the cell divides into two identical nuclei,
each with the same type and number of chromosomes. The cell's DNA is
duplicated during this phase. Sometimes the cell's DNA isn't copied
properly resulting in cancer-type cells. 2. Cytokinesis is when the
cytoplasm divides into two identical daughter cells. Each cell is
genetically identical and both are a similar size.

Answer:
C
Explanation:
Ribosomes are organelles which produce protein inside a cell. They do the same even if they are on an ER membrane.
