What happens to electrons when pigments in photosystem 2 absorb light?

Biology

gladu [14]3 years ago
5 0

When one of the many pigments in the photosystem II absorbs light, the energy is directed inward from pigment to pigment until and unless it reaches the center of reaction. There, energy is conducted towards P680, thus, boosting an electron to a higher level of energy.

Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

Answer:

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.

eimsori [14]

Answer:

Height is affected by multiple pairs of genes on different chromosomes.

Explanation:  

The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
