Answer:

D. streak plate

Explanation:

A geologist use a streak plate to find the color of a mineral in its powdererd form.

To determine the color of a mineral, the geologist uses a technique called color of the stripe or footprint.

This technique involves taking the mineral and spreading a part of it on a plate to determine its color.

This is a mineral identification technique since its composition can be determined according to its colors.

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.
