Answer:
B
Explanation:
Sperm is produced in the testicles, eggs are produced in the ovaries.
The correct option is this: NATURAL SELECTION FAVOR G6PD DEFICIENCY AS COMPARED TO MALARIA.
As we are told in the passage given above, G6DP enzyme helps the red blood cells to function very well. So those people who lack this enzyme have red blood cells that are not functioning very well and this usually result in heamolytic aneaemia. Remember that the parasite that cause malaria normally need red blood cells to survive, thus, for people who lack G6DP malaria can not survive in their blood. Since lack of G6DP enzyme mostly occur in people of African origin where mosquitoes abound, researchers believe that the lack of G6DP enzyme in these people red blood cells is a natural selection method by which the body is preventing itself from been attacked by mosquitoes.

Answer: B
Explanation: A closed system can be defined as a system that does not allow for an exchange of matter with its surroundings.
An estuary where fresh water and ocean water mix is not a good example of a closed system because fresh water and ocean water mix out in the open and matter is exchanged.
A living single-called organism such as phytoplankton does not constitute as a closed system because in order for the phytoplankton to be considered alive it needs to interact with its surroundings i.e light from the sun so photosynthesis (converting light energy into chemical energy to be used by organism) can occur. This also happens out in the open
A river that flows into the ocean does not fit into the closed system definition. This is because a river that flows into the ocean allows for itself (matter) to mix with that of the ocean in an open space (rivermouth).
Therefore option B is the answer because it fits the definition. A chemical reaction within the deep ocean organisms that allows them to glow happens within (inside) the organism, making this system closed, hence there is no exchange of matter with surroundings.
Answer:
The exponential growth model shows a characteristic curve which is J-shaped while the logistic grown model shows a characteristic curve which is S-shaped. The exponential growth model is applicable to any population which doesn’t have a limit for growth. The logistic growth model is applicable to any population which comes to a carrying capacity.
