<span>If ice were denser than liquid water, icebergs would likely sink (even given that sea water is denser than normal water). If this were the case then oceans would likely freeze over. (For example, ice laid down in the winter months would not completely thaw in the summer months, and the next winter cycle would result in a net increase of ice).</span>
Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product.<span> The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.</span>
<span>Asxual resproduction takes place by only one organsim. There is no fusion, no chnage in the chromosome numbers. Thus, an asexual reproduction produces offspring by the process of mitosis, where each cell divides and form two daughter cells, which are similar to each other.</span>
Answer:
The correct statements are:
- Meiosis results in four haploid daughter cells.
- During meiosis, the 2N mother cells produce N daughter cells.
- In both processes, DNA replication must occur.
- Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.
Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.
It plays important role in growth and repair of cells and tissues in multi-cellular organisms.
Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells
It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.
Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.
This would be called an ion. Tch.
