How does blood plasma affect the way blood reacts when different blood types are mixed

Explanation:

An ABO incompatibility reaction occurs when we receive the wrong type of blood during a blood transfusion. Four main types of blood groups are A, B, AB, and O. Our immune system will produce antibodies against any blood antigen. That is A blood creates antibodies against B antigens. A person with type A blood receiving a transfusion of type B or AB blood have an ABO incompatibility reaction. An ABO incompatibility reaction system attacks the new blood cells and kills them. you have type AB blood, you have both A and B antigens,  which means you are a universal recipient and you can receive any type of blood.  you can donate blood to other people who have type AB Blood group. You have type O blood, which has no antigens, you are a universal donor. You can give your blood to anyone, but you can only receive type O blood.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
