Answer:
The correct answer will be-
1. Mitosis
2. Meiosis
3. Mitosis
4. Meiosis
5. Meiosis
6. Meiosis
Explanation:
A cell can divide by one of the two ways of cell division which are: Mitosis and Meiosis.
During mitosis, a cell undergoes four stages of distribution of nuclear material which are prophase, metaphase, anaphase, and telophase and easily characterised.
The mitosis division produces cells with the same genetic material called clones and is involved in the division of the somatic cells. This helps in the growth and repair of the damaged tissue.
Meiosis type of cell division divides and form the four haploid cells from parental cells. The process produces haploid cells in two stages: Meiosis I and Meiosis II. The tetrad formation takes place during the prophase I of the meiosis I.
I believe it is A because Living things respond to changes, each and every living organism is made up of cell and adapting to changes is same as responding to changes.So, only one left is A.
Answer:
<em>Like every other organism the population size of the humans have increased over time.</em>
Explanation:
With the improvements in science and technology, life becomes better and better for human beings. In the past, when there were no discoveries for curing diseases, the human population declined because of the spread of various diseases and famine conditions.
But as the developments in the scientific world are made, it has been easier to cure diseases and other problems. As a result, the population size of the human goes on increasing.
Answer:
Viruses replicate only inside host cells.
Explanation:
<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
