Answer:
Small intestine
Explanation:
It is in the small intestine where most food absorption occurs. Specifically, in the jejunum and the ileum. This is the site where nutrient absorption takes place too. Some water is also absorbed here, but the one mainly in charge of that is the large intestine.
Conduction and convection are means of transferring heat, the important difference is the medium through which the heat travels. Conduction occurs when heat is transferred through solid objects, like a bar.
Keystone species, they kinda hold the food webs together
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:
<u>Generate new ideas</u>
<u>There are many branches of science</u>
Explanation:
Of course many would agree that science has become our way of life, it shapes how we work; by enabling us to generate new ideas. For example, one famous idea that was generated as a result of science is the electric lightbulb by Thomas Edison. Just think of how the world would have been if there weren't any light bulbs to beautify our cities.
Also, science has many branches; making it a very interesting field of study. The major branches include life science, physical science, and earth science.
