Populations evolve and individual organisms do not. Evolution occurs through natural selection and survival of the fittest as populations evolve traits that better suit their environment.
Answer:
guard cells
Explanation:
they control the opening and closing of the stomata
In mitosis (regular cell division)
the cell (mother cell) duplicates it's DNA and aligns it down the center of the cell, so that when it splits each new cell (daughter cell) gets the exact DNA as the mother cell
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.
