As the sickle cell allele was a mutation in the cell, but it helped prevented Malaria in the countries close to the equator. As this mutation helped many resist against Malaria and nature did not let this mutation die out because it still helps many people.
Answer:
Explanation:
Our bodies are comprised of cells, and contrasted with us they're small. ... Furthermore, infections are more modest again — they're about a hundredth the size of our cells. So we're around multiple times greater than our cells, multiple times greater than microbes, and 10 million times greater than your normal infection
The answer is the first E. Hope this helps! :D
Hi the answer to your question would be, Theremohaline circulation is mostly driven by global density gradients created by surface heat. So, deep ocean currents are caused by the water's density, which is controlled by the temperature (greek word thermo) and salinity (haline). This is thermohaline circulation described. Now once the sea water gets more saltier and then ice forms some salt is left behind and then density increases & starts to sink. Now surface water comes in to replace the sinking water & the temperature drops and then it becomes cold & salty enough to sink. This initiates the deep ocean currents which drives the global conveyor belt. Let me know if you need me to explain more. Hope this helped :)
Answer:
Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.
