That's intimidating, lol!

Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.

Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.

Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.

Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.

This means that choice A is true!

What happens to a sedimentary rock after tectonic plates push upwards? What would it turn into?
tester [92]
Hi, sounds like it would turn into B). Metamorphic Rock. Igneous rocks are only formed when melted rock hardens and solidifies. Sediimentary rock is formed when sediment is deposited out of air, ice, wind, gravity or even water. I Doubt it would remain a sedimentary rock so the best answer would be metamorphic rock. Hope this was correct. :)

Mendel did experiments in which he kept track of the inheritance of seed texture (wrinkled or smooth). First he created true-bre
sveticcg [70]

Answer:

smooth was dominant over that for wrinkled

Explanation:

In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.

The substance used to separate the proteins from the dna
Genrish500 [490]

DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.

<h3>What is centrifugation?</h3>

Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.

It is the frequently applied techniques in the molecular biology laboratory.

The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.

Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
