Match the following. 1. period during the life of a cell when it has finished mitotic division G1 phase 2. period during the lif
zimovet [89]

Ans.

The cell cycle includes a series of events that results in the formation of daughter cells from a single parent cell. These events include interphase, followed by M phase. The interphase consists of three phases, G0 (Gap 0) phase, G1 phase, S (synthesis) phase, G2 phase, while the M phase consists two phases, karyokinesis (mitotic or meiotic phase) and cytokinesis. At the end of cell cycle, cell enters into G0 phase again and the cycle goes subsequently.

The sequesnce of cell cycle events can be written as follows:

G0→G1→S→G2→M→G0→G1→....

Thus, according to the cell cycle sequence, these terms can be matched as:

1. When a cell finishes its mitotic division, it enters to G0 phase, which is also known as rest phase. Thus, statement 1. matches with G0 phase.

2. The period between end of mitosis and synthesis of genetic material for next mitotic division shows G1 phase, in which cell prepares itself for division. Thus, statement 2. matches with G1 phase.

3. The period of interphase between synthesis of new genetic material and the beginning of mitosis is G2. Thus, statement 3. matches with G2 phase.

4. The period between two mitotic division is interphase. Thus, statement 4. matches with interphase.

5. The period of cell division, during which a cell is performing actual cell division is M phase. Thus, statement 5. matches with M phase.

6. The period of interphase, during which genetic material gets doubled is synthesis or S phase. Thus, statement 6. matches with S phase.

Which best describes Darwin's studies that led to the theory of evolution?
ddd [48]

Answer:

The answer is B, extensive research of an individual organism over many years.

Explanation:

The question is asking, what best describes Darwin's studies that led to the theory of evolution, it would be a lot of research over a long period of time. Think, if you were to do a school project, would you get your best results over a short or long period of time with little or a lot of evidence/research? So, B is the best answer, I believe.

Genes _____.
lys-0071 [83]

Answer:

The correct option is D. Genes determine the trait of an organism.

Explanation:

Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.

Option A is false because each gene is made up of different nucleotide sequences.

Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.

Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.

Option E is false because genes are not units of RNA. Genes are made up of DNA.
