If the blockage is removed from the blood vessel, what will happen to blood flow after removal?
Answer:
the blood would stop pumping, because the blockage allows the blood to move one way, but when there is not blockage, the blood would enter from both ways making it impossible to regulate

BRAINLYMENTALMENTEWhich is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!

How are the spines on a cactus different from the leaves on an oak tree?
1. They provide nutrient intake
2. They provide heat exchange
3. They reduce water loss
4. They reduce oxygen release
Answer:
3.
Explanation:
because normal leaves transpire and release water where as spine don't transpire
how are adaptation and variation similar?
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

describe the product of mitosis
The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes. ... A chromatid, then, is a single chromosomal DNA molecule. In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.
The purpose of transcription is to create
A. a sequence of RNA bases that complements a sequence of DNA bases.
B. a sequence of DNA bases that duplicates a sequence of RNA bases.
С. a sequence of RNA bases that breaks down a sequence of DNA bases.
D. a sequence of DNA bases that deletes a sequence of RNA bases.
Answer:
B. a sequence of DNA bases that duplicates a sequence of RNA bases.
Explanation:
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.

Past
Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.

List 5 uses for proteins in the cell.
Answer:
Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Finally, they keep your immune system strong, transport and store nutrients and can act as an energy source, if needed.
Explanation:
Hope this helped Mark BRAINLIEST!!!
Proteins help in cell structure formation, and cell transport, allow biochemical reactions, cell repair and also help in cell division.
What are cellular proteins?Proteins present in the cell are of various kinds. They are formed in the cell by the process of DNA transcription and translation.
The proteins formed in the cell then go on to perform various functions. The cellular proteins form the structure of the cell. They do that either by forming the cell membrane or the membrane of the organelles.
The cellular proteins also help in transport of nutrients. This transport is of two types. It can transport materials from inside to outside of the cell and vice versa. It can also transport materials inside the cell to other organelles.
Various biochemical reactions in the cell are possible because of the cellular proteins. The proteins formed in the cell are also used for cell repair and cell division.
Therefore, the various functions performed by the cellular proteins are cell structure formation, cell transport, allowing biochemical reactions, cell repair and help in cell division.

- Found in extreme environments like volcanic vents
- Am unicellular
- My cell wall does not contain peptidoglycan
a- Plantae
b- Eubacteria
c- Fungi
d- Archaebacteria
Answer:
The correct answer is - d- Archaebacteria.
Explanation:
Archaebacteria is the organism of the prokaryotic cell organism and lacks double membrane-bound organelles and nucleus and has the chromosomes present in the nucleoid.
These cells are different than eubacteria as they lack peptidoglycan or murein in their cell walls like eubacteria. This group of organisms is found in extreme conditions like halophile, drought, or volcanic heats. Archaea is the third domain other than eukarya and bacteria.
