Answer:
A. S phase
Explanation:
The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.
Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.
In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.
They use it to react carbon dioxide<span> with water to make a </span>sugar<span> called </span>glucose. Theglucose<span> is used in respiration, or </span>converted<span> into </span>starch<span> and stored. </span>Oxygen<span> is produced as a by-product. This process is called photosynthesis.</span>
<span>An atom that has gained or lost electrons is called an ion</span>
The new species would try and crossbreed possibly, or see them as weak and kill them off and take their resources.
