The answer is mitosis.
Mitosis and meiosis are both 2 different kinds of cell division process. In mitosis, a parent cell will divide and produce 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. Since this process produces identical cells, it is mostly used in growth, tissue repair etc.
On the other hand, meiosis is the cell division process where a parent cell produces 2 daughter cells, and the two daughter cells produces 4 more daughter cells, and these daughter cells are genetically different to each other, they only have half of the chromosomes than its parent cell. Meiosis is used in producing gametes, so that when 2 gamete fuse together, in fertilization, the zygote can retain the correct amount of chromosome.
Therefore, since skin is not used in reproduction and its chromosomes should be the same as the original skin cell, mitosis is the answer.
An antigen triggers a response from the immune system and an antibody is produced. All antibodies are immunoglobulins, therefore, the correct answer is immunoglobulin. More specifically, an immunoglobulin is a protein produced by plasma cells to fight and neutralize pathogens. To do so, the immunoglobulin has a specific region which is complementary to a specific region of the antigen. Immunoglobulin's mechanism of action is to bind to the pathogen and either block its action or trigger a response of other cells of the immune system.
The correct answer is: desertification.
Desertification is a process in which a land which was not a desert before, becomes one. This process can include drying out- through for example loss of water source, such as river diversion- and the loss of vegetation.
The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

Explanation:
Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
