Answer:
(B) agglutination with anti-A antibodies.
Explanation:
ABO blood type is based on two types of antigens: A and B antigens. The anti-A antibodies react with antigen A while anti-B antibodies react with antigen B.
Blood type A has antigen A on the surface of its red blood cells and anti B antibodies in its plasma. Due to the presence of antigen A on its red blood cells, the blood type A shows agglutination with anti A antibodies.
Scientists can access the risks of trans fats by conducting an appropriate experiment which will show the effects of the fats on the human system.
This can be done by feeding known quantity of trans fats to rats over a specific period of time. During the period, the change in the rat weights will be measured on the daily basis and every other changes that is noted in the rats will be noted down. A control group of rats will be included in the experiment; these rats will be given normal rat feeds and not trans fats.
When the period of feeding is completed, the rats will be killed, all the organs in the rats such as liver, blood, brains, kidney, etc will be harvested and these organs will then be biochemically analysed in order to compare the changes in them with that of a normal rats.
Rats are usually used in biochemical research because their systems and that of human is comparable. Any negative effect of trans fats that is noted in the rats will also hold true for human beings.
Answer:
1. Medial collateral ligament, lateral collateral ligament, anterior cruciate ligament and posterior cruciate ligaments.
2. Chondromalacia patellae
Explanation:
The knee is a ginglymus that connects the thigh to the leg. It is the largest joint in the human body, that plays a vital role in the horizantal and the vertical movement of the body.
There are <u>four ligaments</u> of knee joint, that joins the femur to the tibia and also provides stability by limiting movement. They are: <u>medial collateral ligament, lateral collateral ligament, anterior cruciate ligament and posterior cruciate ligaments.</u>
Chondromalacia patellae is a medical condition that includes inflammation of the cartilage on the posterior aspect of the patella, which leads to softening of the cartilage.

Answer:
The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.
Explanation:
There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
