Answer:
The correct answer will be- arteries→capillaries→veins
Explanation:
The circulation of blood in the closed circulatory system flows through blood vessels. These blood vessels show structural differences in response to the pressure exerted by the blood on the surrounding medium.
The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.
The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.
When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.
Thus, arteries→capillaries→veins are the correct answer.
Answer:
C. But see the answer under C. Apparently C is the accepted answer.
Explanation:
A. Not A.I don't think that's a problem for gulls especially on beaches.
B. Not B. Their feather do not look like they need much help in keeping their feathers attached when in flight.
C. This is not really the answer, but it is the best answer of these 4. The actual answer is that the bones are porous for better air intake which provides more oxygen and hence they are better able to fly.
D. Not D. Food has nothing to do with the problem. Birds get an adequate amount of food without their wings being porous. See the answer for C.
The factor that poses the greatest threat is loss of habitat. Have a nice day!

Answer:
Agglutination or clumping occurs when blood that contains the particular antigen is mixed with the particular antibody.
Explanation:
Clumping of blood types takes place thus;
A+ - Agglutination with Anti-A and Anti-Rh. No agglutination with Anti-B.
A- - Agglutination with Anti-A. No agglutination with Anti-B and Anti-Rh.
B+ - Agglutination with Anti-B and Anti-Rh. No agglutination with Anti-A.
B- - Agglutination with Anti-B. No agglutination with Anti-B and Anti-Rh.
AB+ - Agglutination with Anti-A, Anti-B and Anti-Rh.
AB- - Agglutination with Anti-A and Anti-B. No agglutination with Anti-Rh.
O+ - Agglutination with Anti-Rh. No agglutination with Anti-A and Anti-B.
O- - No agglutination with Anti-A, Anti-B and Anti-Rh.
