Answer:

A. Interphase

Explanation:

Interphase is when the DNA is copying itself. It is being prepared for the cell to divide and one of the key parts of mitosis is when the chromosomes duplicate, so to prepare for mitosis, the chromosomes must duplicate during interphase.

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.

deff fn [24]

Answer;

Because it is cheaper to prevent an illness than to treat an illness

Explanation;

-Health Maintenance Organization(HMO) plans offer a wide range of healthcare services through a network of providers who agree to supply services to members.

-According to HMOs it is better to prevent disease rather than to try to find cures for diseases after they occur, therefore they encourage healthy lifestyle practices.

-Prevention typically consists of methods or activities that seek to reduce or deter specific or predictable problems, protect the current state of well-being, or promote desired outcomes or behaviors.

Describe what the completeness or integrity of an ecosystem biodiversity is used to measure
Scorpion4ik [409]

Answer:

Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. Biodiversity describes the variety of species found in Earth`s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem`s biodiversity is often used as a measure of its health.

Explanation: Disruptions can really mess with any physical or biological component of a ecosystem then that ecosystem leads to shifts in all populations. I hope this answer helps you!
