Answer:
Muscle cells and skin cells look and behave differently because their genes are being expressed differently.
Explanation:
- Genes are the sequence of nucleotide that has all the information about the functioning and characteristics of particular cells.
- All genes are actually present in our liver cell but the thing that matter is the gene is expressed differently for different type of functioning.
- So even having the same gene the cells might look different and behave different, its all about turning the gene "on" and "off".
I believe the answer should be mitosis.
Mitosis is a kind of cell division that produces 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. It is a process of exact duplication of the genetic material (chromosomes) in the parent cell, then dividing, each with the same original number and sequence of chromosome.
It is used for growth and development because they're the process of where the number of cells increases, and how? By mitosis. These new cells must be exactly identical to the other originally existing cells, as for example you wouldn't suddenly grow some skin cells as a replacement of nerve cells. Mitosis of nerve cells produces the same type of nerve cells, mitosis of skin cells produces skin cells.
Therefore, your answer should be mitosis.
Answer: we can see the nucleus obviosly in the eukaryotic cell
Answer:
Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.
Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.
