Answer:

5. when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent

6.They are moving toward each other

7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise

8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.

Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.

Compared the Mendelian Dominance, how to incomplete dominance and codominance increase the number of phenotypes? Provide an exam

REY [17]

Answer/Explanation:

<h3>Incomplete dominance</h3>

In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.

For example, consider flower colour.

If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))

<h3>Co-dominance</h3>

In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.

For example, consider flower patterns.

If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))

A, this is my guess because topsoil is made mostly of humus(sand, silt, clay and broken down organic matter) and the rest of the answers don’t make sense, hope this helps :]

How are proteins built using the information provided by a molecule of RNA?

Paladinen [302]

Answer:

Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.

Explanation:

Fatty acids, in particular, essential fatty acids alpha-linolenic and linoleic acid are intimately related to managing inflammation in the body.
