Why is there an uneven distribution of charge across the membrane? There is an uneven distribution of charge across the membrane because the sodium/potassium pumps out 3 sodium ions out of cell for every 2 potassium ions resulting in an unequal distribution of ions across the cell membrane. What is the transport of ions across […]

What is nodes and internodes in plants? The node and internode are two structural components of the stem of a vascular plant. The nodes are the specific areas on the stem where the lateral bud is present from which the leaves, branches or flower buds grow out. In comparison, an internode is the distance between […]

How can mutations be passed to offspring? Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. Mutations can introduce new alleles into a population of organisms and increase the population’s genetic variation. […]

What is an illness that can pass from one organism to another called? Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to […]

What are 3 reasons why cells need to divide? Terms in this set (3) 1 growth. Go from one cell/( zygote to a trillion) 2 replace. Repair\ 50 million cells die second. 3 reproduction. ( make cells for reproduction make specialized sex cells) Which is a reason why cells divide? Cells divide for many reasons. […]

What were the seven pea traits that Mendel studied what are the two phenotypes of each trait? On the next screen, he reveals that there are seven different traits: Pea shape (round or wrinkled) Pea color (green or yellow) Pod shape (constricted or inflated) Pod color (green or yellow) Flower color (purple or white) Plant […]

Why is vascular tissue advantageous? The adaptive advantage of vascular tissues is that it provides an internal skeleton and stability for the plant. Additionally, the tissues allow the plant to transport water, organic molecules, and other materials throughout the plant, and this allows the plant to live in a variety of environments. What is vascular […]

How does crossing over contribute to genetic diversity? Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity. What are two ways that increase genetic diversity in sexually reproducing […]

What happens to energy as it moves through a food chain and how can it be calculated? A: Energy flows in a food web by being transferred to and between organisms as they undergo photosynthesis, are consumed by another organism, or decompose. Q: How can energy move through trophic levels? A: Energy moves through trophic […]

Which sentence best describes a cell that is isotonic for a substance? The answer would be C) The solute concentration is equal on both sides of the cell membrane. This is correct because in an isotonic solution, they would have the exact salt concentration as the blood surrounding the cell. What happens to a cell […]
