<h3><u>Answer and explanation;</u></h3>
- Density plays an important role in the study of Earth. It affects Earth's climate, plate tectonics, and subduction.
- <em><u>Subduction occurs at the convergent plate boundaries. Density plays a major role for subduction to take place. Subduction is driven by the excess density of the lithosphere compared to the underlying asthenosphere.</u></em>
- <em><u>Oceanic plates are denser and colder than continental plates, because the ocean cools them. Subduction can occur between an oceanic plate and a continental plate, or two oceanic plate or two continenetal plates.</u></em>
- During subduction between oceanic and continental plates, mantle convection drags the denser oceanic plate downwards and forces it down into the asthenosphere.
- During subduction between two oceanic plates, mantle convection drags the older, denser oceanic plate downwards and forces it into the asthenosphere.
- During subduction between two continental plates, there is no mantle convection, because the two plates are of similar densities.
Answer:
The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean. ... The rift valley is 1 to 3 km deep, about the depth and width of the Grand Canyon. In contrast, the East Pacific Rise spreads fast at rates of 6 to 16 cm per year (more than 20 cm per year in the past).
Answer: Dominant allele codes for a functional protein. Recessive allele codes for a less functional or nonfunctional protein, or it does not code for any protein.
Explanation:
Alleles are different forms of a gene. There are two types, dominant and recessive allele. Heterozygous organisms have one of each, and the dominant allele is expressed. Homozygous organisms have either two dominant alleles or two recessive alleles.
<u>A dominant allele produces a functional protein</u>, even in the presence of a recessive allele, because only one copy of the allele is enough and it masks the effects of the recessive allele. This dominant trait is shown in individuals who are homozygous dominant or heterozygous,
<u>A recessive allele produces a less functional or nonfunctional protein, or it does not code for any protein at all.</u> A recessive allele does not become a trait unless both copies of the gene are present.
Answer:
Perishable foods should never be thawed on the counter or in hot water and must not be left at room temperature for more than two hours. There are safe ways to thaw food: in the refrigerator, in cold water, and in the microwave.
Explanation:
What factors influence the input and output of carbon through Earth's spheres? The oceans on Earth act as carbon sinks. The combustion of fossil fuels contributions to an increase in atmospheric carbon dioxide. Animals are solely responsible for the release of carbon dioxide via respiration
