10. disappears during prophase
Answer:
False.
Explanation:
Note that, osmosis is considered as the passive movement of water because,it involves the movement of water from a region or area where concentration is high to the region or area of low concentration. This is the reason why it is compared to or described as a type of diffusion.
This process is known as passive transport or passive movement of water. And it is known to be water specific process.
That is why it can be compared to diffusion of ions or other small molecules in physics.
Curare will bind to the receptor but it doesn't cause the ion to flow inside. This will prevent the person from sent signal to the muscle. When the person trying to move the muscle, curare will also prevent acetylcholine to bind so there will be no muscle contractions. The symptoms would be paralyzed of muscle that uses ach receptor.
The answer is: <span><span>has antigens A and B on the red blood cells
</span>
Human blood contains either:
A antigens (A)
B antigens (B)
A and B antigens together (AB)
none of these antigens (O)
corresponding to the A,<span> B</span>,<span> AB</span>, and O blood types, respectively.
Antigens are molecules that can cause an immune response to be mounted against them in the form of antibodies. Antigen is an abbreviation for 'antibody generator'.
In the case of the ABO blood groups, the antigens are sugars on the red blood cells.
Antibodies are complex proteins made by certain immune cells, and these proteins have the ability to bind foreign material or microbes, which can block their harmful action and label them for quicker elimination.
Example:
When a person has a blood type with a particular antigen (e.g. A), he or she won't produce antibodies against that blood type, so they are safe to receive blood from individuals with similar blood types (won't be considered foreign). They can also receive blood from blood type O donors because they don't have any antigens that would cause an immune response.
But this person with blood type A, has antibodies against blood type B (to defend oneself from foreign material), so if they were transfused type B blood in this case, they would experience a dangerous immune reaction as the antibodies would bind the B antigens of the B blood type red blood cells.

Blood type O individuals are universal donors = can donate blood to anyone.
Blood type AB individuals are universal receivers = can receive blood from any group.</span></span>
This is false. A waterfall causes a lot of erosion.
