Hey there!

Answer: 400 k-cal

I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.

Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal

As we plug in this formula into our problem above, our answer would be explained below.

40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal

Answer: 400 k-cal

Answer No 1:

The trait which is being studied in the cross is the height of the pea plant.

Answer No 2:

The two alleles for this trait are tall height allele which we can write as T and the allele for short height which we can write as t.

Answer No 3:

The allele for tall height is the dominant allele. We can say this because when a cross between a dominant homozyous and a recessive plant were made the offsprings resulted in the tall plants which is the F1 generation in the figure. As a dominant trait masks the recessive trait, hence we can say that the tall height allele is dominant over the short height allele.

Answer No 4:

The allele for short height t is recessive because as we can see the short height trait is being masked by the tall height trait in the F1 progeny. In F2 progeny, there are more number of tall height plants produced which further prove that short height is the recessive trait.

Answer No 5:

The F1 offsprings will have a dominant tall height allele, T, and a recessive short height allele, t. The dominant allele was inherited from the tall parent and the short height allele, t, was inherited from the recessive parent.

We can say that because the F2 progeny shows some plants to have short heights which is only possible if the F1 generation has heterozygous dominant (Tt) alleles.

What phase of the cell cycle comes before prophase stage of mitosis
77julia77 [94]

Hey.

Your anserw is  interphase.

Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase. Each stage of mitosis is necessary for cell replication and division.
