Answer:
B
the tendency of the body to maintain inner balance despite changes in external conditions
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
A population will have a high number of people who are carriers of the
sickle-cell trait due to the high prevalence of malaria.
Malaria is a disease which is spread by the vector known as Mosquito when
humans are bitten. Malaria is deadly and is effectively treated with the use of
artemisinin-based combination therapy (ACT).
There has been evolutionary adaptation by humans on how to fight
malaria.The presence of the sickle cell trait has been linked to making more
resistant to malaria. This is why we have more sickle cell carriers in areas
with high malaria prevalence such as Africa than those with low prevalence.
