Answer:
C
Explanation:
Adenosine triphosphate (ATP) links most cellular exergonic and endergonic chemical reactions. To obtain energy to do cellular work, organisms take energy-rich compounds such as glucose into the cell and enzymatically break them down to release their potential energy. Therefore, the organism needs a way to trap some of that released energy and store the energy in a form that can be utilized by the cell to do cellular work. Principally, energy is trapped and stored in the form of adenosine triphosphate or ATP.
Answer:
Hi there! Hopefully this helps!
Explanation:
The correct answer is A(the first one). When one species is removed from a food web, it eventually affects all organisms that were interconnected to that species.
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>
Answer: a. A survey to access the oral needs of school children or adults including a visual inspection of the mouth.
Explanation:
The basic screening survey is a tool which was developed by the Association of the State and Territorial Dental Directors. This is conducted to monitor the oral health of the children as well as the adults. It involves the visual inspection, dental carries, oral examination for the tooth decay and other evaluations related to the oral health.
