Astudent was observing slides of cell division in one of the slides he noticed loosely

Interphase as it prepares cell for division by occurrence of some important biological functions and duplicate genetic material (DNA)

DNA replication occurs during the S phase.

Explanation:

During the processes of the cell cycle is a phase called the S phase (Synthesis Phase) in which the DNA is replicated, occurring between the two phases G1 and G2.

Complete accurate DNA instructions in the cell must be duplicated in order to produce two similar daughter cells which occurs during the S phase where loosely coiled chromatin can be seen.

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.

The correct answer is:

S phase

Explanation:

S phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Accurate and accurate DNA replication is needed to counter genetic exceptions which often lead to cell death or disease. DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA structure and mitosis, the cell will remain to grow and design new proteins.

It would be "A. S phase". I think so.

Out of the choices given, the phase of the cell cycle is the S Phase. The correct answer will be A. 

Prophase, because the chromatin haven't lined up in the middle (metaphase), haven't spread to either side of the cell (anaphase), and the cytoplasm hasn't begun to divide (telophase). SO using process of elimination prophase would be the correct answer.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
