Answer:
The secondary immune response is the immune response when the same antigen , memory cells that was encountered before is remembered and the immune system make antibodies to counter it.
Explanation:
There is a difference between the primary immune response and secondary immune response.

While the secondary immune response occur when the same antigen that was encountered the first time is encountered the second time and it lead to the stimulation of memory cells to produce more and high quantities of antibodies to fight foreign substances.

The answer to this question would be: <span>a. optic chiasm
The optic nerve will be crossed in optic chiasm. Only a part of the optic nerve is crossing the midline. So, if there is a damage in the nerve after crossing, the visual loss will not only appear in one eye but half of both eye. Damage in right visual cortex will cause the left and right eye losing their half (left part) of their visual field.</span>
Answer:
Option D.
Explanation:
Scientific method is the method of experimentation that is used in science to explore observations and answers to questions on natural world. It involves making observations, formulating hypothesis and conducting scientific experiments.
Scientific processes is the end result of scientific method. It involve step by step approaches use to carry out scientific experiments about natural world.
