Answer:

PLATO ANSWER

Explanation:

Bleeding would occur because the baby is growing near the vaginal canal, which leads to the outside of the body. The cervix is the bottom portion of the uterus, so if the uterus is damaged, the entire uterus may need to be removed.

Plant reproduction by tissue culture differs from reproduction by meristem culture because
Leviafan [203]

The answer is; B

Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.

Dima020 [189]

Answer:

A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>

Explanation:

Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.

When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.

Changing one base in a gene could have the
saw5 [17]


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.
