Answer:

The correct option is A) RNA polymerase.

Explanation:

RNA polymerase is an essential enzyme complex to carry out transcription, these enzymes are responsible for transcribing DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. This process is the first step of gene expression, and is called transcription. RNA polymerase binds to DNA in a very particular region or sequence, called a promoter.

Does grain size determine the porosity of a sediment type?
aleksklad [387]

Answer:

Yes

Explanation:

In sediments or sedimentary rocks the porosity depends on grain size, the shapes of the grains, and the degree of sorting, and the degree of cementation. Well-rounded coarse-grained sediments usually have higher porosity than fine-grained sediments, because the grains do not fit together well

) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di
Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.  

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

HELP!!!! Time crunch!
Mila [183]

Answer:

Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.

The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.

However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).
