Answer:
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles.
Explanation:
Answer:
D) metaphase
Explanation:
Mitosis is a type of cell division in which the cell divides its replicated chromosome in equal amount in two daughter cells. Mitosis takes place in four phases: Prophase, Metaphase, Anaphase and Telophase.
Metaphase is the stage of the cell division during which the chromosome is present in the highly condensed form present in the centre of the cell. The chromosomes are aligned at the equator of the cell.
Thus, metaphase is the correct answer.
The answer is “Variation that decrease reproductive success are more likely to be passed on.”
<span>Stabilizing selection is at work in this case. This is the force that allows a population to gradually center on a mean value due to a presence of a non-extreme bodily trait. The more extreme examples of the trait lead to the organisms being selected out, and the trait that is the least conspicuous wins out in the long-run.</span>
Answer: Cytotoxic T cells
Explanation:
A Cytotoxic T cell is a cell whose activation is mainly aimed at destroying cells that are infected by virus. It is a type of white blood cells that destroys cancerous cells or cells that are impaired especially by viruses. A Cytotoxic cell is also known as T-killer cells, Cytolytic T cells, T lymphocyte.
Cytotoxic T cells destroy target cells by prearranged apoptoses.
