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.

Throw some loght on dichloroindophenol chemical and its function in photosynthesis
madam [21]

Answer:

Dichloroindophenol chemical act as electron acceptor in photosynthesis

Explanation:

DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis

It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant  that is produced at the time of photosynthesis with in the chloroplasts.

Identify the correct order of events that allow nutrients from foods to be used by the body. Group of answer choices digestion,
Lera25 [3.4K]

Answer:

The correct answer is- digestion, absorption, transport, elimination

Explanation:

The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.  

In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.  

This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.

Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.

Therefore the correct order are: digestion → absorption→ transport→ elimination.

in which location is water most likely to be transferred the fastest from the hydrosphere to the atmosphere?
Archy [21]
Probably smaller bodies of water, as less water will heat up and evaporate faster.
