Answer:
Cells must divide to perform functions such as growth of the organism, replacement of damaged or old cells, and asexual reproduction in some organisms.
Explanation:
Answer:
stronger and longer organ are able to mate more with females, whereas the shorter one didn't stand a chance.
Answer:
interphase. period of the cell cycle between cell divisions.
Mitosis. cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
cytokinesis. division of the cytoplasm during cell division.
Explanation:
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.[1] In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.
The correct answer would be population size!
<u>Thermohaline</u> is a large scale ocean water circulation driven by density differences due to the changes in surface water temperatures and fresh water fluxes.
Explanation:
Thermohaline circulation is the ocean circulation driven by variation in ocean densities. The deep ocean currents are influenced variations in the temperature controlled water density (thermo) and the salinity (haline) of the ocean waters. This circulation happens due to the thermal and haline influences on the ocean waters.
Due to extremely cold water, the ocean waters in the Earth’s polar region gets very cold and forms sea ice leaving salt behind. This decreases sea water temperature but increases the salinity levels.
With increase in salinity, the density of the water also increases which makes the water heavy and sink and the surface water moves in to fill the sunken sea water.
Again this surface water also becomes cold and the cycle continues leading the global ocean conveyor belt and causes freshwater fluxes depending upon the latitude of the ocean.
