A cell in prophase I of meiosis has twice as much DNA as each of the daughter cells following cytokinesis of meiosis II.
Meiosis is reduction cell division through which gametes (eggs or sperm cells) are formed. Reduction division means that four haploid cells (n) are produced from a single diploid cell (2n). The number of chromosomes is reduced by half during meiosis but during fertilization are returned to the full numer, when the two gametes fuse.
Van de waals are considered the weakest bonds between any two molecules
Answer:
A. The plant would wilt.
Explanation:
In order to stay healthy and fresh, plants like every other living organism require certain substances. One of those substances is WATER, which the plant gets by absorption via the root hairs. The water circulates throughout the plant with the aid of a water-conducting vascular tissue called XYLEM. Without the xylem, water will not be transported throughout the plant.
The xylem tissue helps provide structural support to the plant as it helps the plant cell to be turgid. A non-functional xylem means the conduction of water is impossible, hence causing the plant cells to become flaccid and lose strength; a process called wiltering.
Answer: Feedback loops are biological mechanisms whereby homeostasis is maintained. Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
