The DNA molecule is shaped like a ladder that is twisted into a coiled configuration called a double helix. The nitrogen bases form the rungs of the ladder and are arranged in pairs, which are connected to each other by chemical bonds.

one duplicated chromosome has two sister chromatids. in prophase of mitosis you see 18 duplicated chromosomes in a cell. this ce
Mice21 [21]

In the prophase of mitosis if 18 duplicated chromosomes are in a cell then the number of chromosomes in interphase is <u>9</u>.

A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.

A sister chromatid is one that has two identical copies of a chromosome that are connected by a common centromere during chromosome DNA replication. In other words, a sister chromatid can also be thought of as "one-half" of a chromosome that has been duplicated. A dyad is a pair of sister chromatids.

Sister chromatids, which are firmly connected at the centromere region of each chromosome, are created as a result of DNA replication during the S phase (synthesis phase). Each chromosome is a duplicate at this point and is made up of two sister chromatids.

When roots take up mineral ions, they are built up against their concentration gradient. both anion and cation transport utilize
attashe74 [19]
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
