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.

What types of antigen do T cells NOT recognize? What types of antigen do T cells NOT recognize? self-antigens bacterial antigens
Stolb23 [73]

Answer:

Self-antigens are not recognized and attacked by the T cells.

Explanation:

In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.

Flowers are a collection of _____ tissue produced by some plants.
Lostsunrise [7]
There are choices for this question namely:

1. Sterile
2. Reproductive
3. Both
4. Neither

The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.
