How do biologists describe the order of the stages of the<br> cell cycle?
ololo11 [35]
The cell stays in the interphase stage the longest. The interphase stage includes the G1 phase which is the initial growth of the cell. Next is the S phase and in simple terms it’s just the replication of the DNA. Next is the G2 phase which is the continued phase of cell growth. After interphase is completed, the cell enters prophase, then metaphase, then anaphase, then telophase, and finally cytokinesis.

A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran
viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C  

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.
