7. _______ currents are responsible for powering the movement of tectonic plates. A. Plutonium B. Tectonic C. Convection D. Plat
Kaylis [27]
The correct option is C.
Scientists believed that the earth tectonic plates are in constant motion, this motion is slow and its rates vary. The motions of the tectonic plates are caused by the convection current which is found in semi molten mantle. The convection current are created by heat within the earth surface. When a semi molten rock is heated, it become less in density compared to its surrounding and thus rises up. When the less dense molten rock reaches the crust above, it spread out and carries the tectonic plate above with it. When the molten magma cools down, it sinks and the whole process is repeated leading to continuous movement of the tectonic plates.

What is the master switch that determines whether an individual develops as a male?
Inessa05 [86]
<span>In human beings the "master switch" that determines whether an individual will become a male is the SRY gene, which is found on the Y chromosome. The sex-determining region Y protein produced from this gene acts as a transcription factor, meaning it attaches to specific regions of DNA and helps control the activity of particular genes.</span>

Alisha and Rob would like to have children. A genetic counselor tells them that they are both carriers of a certain genetic dise
kupik [55]

Hi there!

With mendelian genetics and inheritance, it assumes that there are two alleles (a variant of a gene) for every trait, one from each parent. These two alleles can be dominant or recessive. This would result in different exhibitions of traits - as long as there is only one dominant allele, then the dominant trait is exhibited, even if there is the recessive allele. However, if there are both recessive alleles, then it is the recessive trait which is exhibited.

When a person is a carrier of a trait, in this case a genetic disease, it means that they carry the allele for the disease, but don't exhibit it. This would mean that the allele would be recessive, however they would also have a dominant allele which "overrides" this disease.

Hope this helps!
