The temperature is lowest at the crust. As you get lower into the Earth's surface, the temperature gets hotter.
Answer:
Totipotential.
Explanation:
There are different cell potencies. A <u>totipotent</u> cell is a stem cell that can divide itself and <u>differentiate in any cell </u>that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.
Answer:
B. It allows for genetic variation.
Explanation:
As prophase progresses, homologous chromosomes come to lie side by side and become intertwined rather like a zipper. This process is called synapsis. During synapsis, homologous chromosomes exchange genetic material between one another which allows for genetic variation. This exchange is called crossing over.
Answer:Daughter cells are genetically identical to the parent cells
