Answer:
During meiosis, an event known as chromosomal crossing over sometimes occurs as a part of recombination. In this process, a region of one chromosome is exchanged for a region of another chromosome, thereby producing unique chromosomal combinations that further divide into haploid daughter cells.
Natural selection is where positive traits survive more, allowing those to become more common. Mutation is where radioactivity changes genes in a random way. Natural selection allows positive mutation to become more common. Adaptation is where natural selection works for a species specifically more a new habitat.
Answer:
DNA and ATP 2. proteins and lipids 3. chitin and starch ... Singer proposed the fluid mosaic model of the cell membrane in which the cell membrane consists of a double lipid layer with proteins embedded in it to act as name tags or to aid in movement of larger molecules across the membrane.
Explanation:
Explanation:
the last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.
