The answer would be true

The objective of vaccination is to elicit the primary immune response by introducing pathogen antigens. This antigen can be a whole weakened pathogen or just part of pathogen proteins. 
The antigen will activate the primary immune response cascade that <span>will </span>activate of B-cells and T-cells from the secondary immune response. This will makes secondary immune response ready when the real pathogen comes.

What would be the effect on climate in the temperate latitudes if Earth were to slow its rate of rotation from a 24-hour period
grin007 [14]

The correct option is (E) The climate would stay the same. The only change would be longer days and nights.

If Earth were to slow its rate of rotation from a 24-hour period of rotation to a 48 -hour period of rotation, the climate would stay the same. The only change would be longer days and nights.

<h3>How does the rotation of the Earth affect day and night?</h3>
  • Earth rotates on its axis, or turns, once every 24 hours, carrying us all along with it. We experience daylight when we are on the side of the Earth that faces the Sun. We are now on the side of the Earth that faces away from the Sun, and night has fallen.
  • The Earth revolves counterclockwise, and if we were to look down on it from above the north pole, we would notice that day and night move over our planet from east to west.

Mr Mwape and his wife are both heterozygous tall and brown and have 3 children who are tall and brown and one child who is short
love history [14]

We can explain Mr Mwape that variation in his children through Mendel’s law.

Reason why three children tall and brown one of MR Mwape was short and dark is: -

• Skin color and height is controlled by a lot of genes and every human gets one set of genes from their mother and the other set of genes from their father.

• Now imagine these genes are denoted as ‘T’ for tall and ‘B’ for brown and ‘t’ for short ‘b’ brown. We can assume that MR Mwape and his wife having genotype TtBb.

• During the process of gene segregation and assortment, the majority percentage of children got the heterogenous dominant genotype, which is ‘TtBb’, overlapping the effect of gene ‘t’ and ‘b’. While another child got a homogenous recessive genotype ‘ttbb’ from both the parents, hence the genotype is prominently shown in the fourth child and not in other as gene 't' and 'b' were dominated by genes 'T' and 'B'.
