Single celled organisms are able to maintain homeostasis, withstanding relatively large alterations in their external environments . This is due to the fact that they posses structures that regulate and carry out life functions. They perform all the functions that are necessary for an organism to exist.
The ability to obtain all the substances that are essential for their existence eliminates the need for dependence on other cells. These single-celled organisms are thus able to maintain a relative state of equilibrium within their internal environment.
Answer:
Explanation:
The uterus is a hallow and flattened muscular organ that is the home to developing fetus.It is divide into three parts:fundus, body, and cervix.
Its functions are:
1.to regulate menstural cycle throughout the reproductive period.
2.to pass the sperms towards fallopian tubes for fertilization.
3.to provide site for embedding zygote.
4.to expel fetus through cervix at the time of birth.
Answer:
sexual reproduction, because the genetic material comes from both parents.
Explanation:
The sperm and egg produced contain different combination of genes
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.
