There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
3: B Nervous system. 4: A Sensing and responding to its external environment.
answer: 2) sequence of building blocks of a protein found in a cell.
Just random FYI:
- it is a mutation, that is generally not looked upon as being severe or detrimental to the person
-by changing the base by either adding or deleting from a protein strand will cause the protein to be useless
-frameshift mutation deals with DNA sequence being shifted. For example: a DNA strand looks like a ladder. If one of the rungs on the ladders gets skipped and the next ladder rung gets the code that the previous rung should have gotten, then that is what a frameshift mutation is. Hopefully that makes sense. It's easier to explain if there was a picture.
there are other types of mutation but I won't get into them.
Hopefully this helped and good luck.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.
Proteins serve as antibodies.
