Hello!

For background the plant shown is an orchid. Generally, purple is the dominant color and trait within this species and white the recessive allele.

If we use Mendell's Punnett Square we can actually see that together the pair are codominant with one another.

So the answer to your question would be, c. codominant with the allele for the white flower color.

If only one particular color was showing, we could say that one was dominant over the other. However, due to the fact that both traits show, that means they are codominant ! As recessive genes will not show under the presence of a dominant gene.

Hope this helps answer your question!

What moves the chromatids around during cell division

REY [17]

Answer:

Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell. ... More specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles.

place the following in order from smallest to largest: amino acid, globular structure, CHON, amino acid sequence

Karo-lina-s [1.5K]

The correct order from smallest to largest would be:

H < C < N < O < Amino acid < Globular Structure < Amino acid sequence

The smallest should begin from the basic elements. Among C, H, O and N, the lightest is Hydrogen, followed by Carbon, Nitrogen, and Oxygen. Next is the amino acid which is the most basic unit of protein. This is the linear structure. Followed by the globular structure which is the tertiary structure. The whole would be the amino acid sequence which is quaternary structure.

In what phase of mitosis are chromosomes moving toward opposite sides of the cell?

zloy xaker [14]

Answer:

Anaphase

Explanation:

Before the mitosis process (where cells multiply creating two new daughter cells from a single cell) chromosomes are replicated and remain attached to their replicates, then they are condensed forming microtubules as they align on the metaphase plate. Now the sister chromatids (replicates) begin to separate to the opposite poles due to the action of the spindle in anaphase (You can observe this in the image I added). Then telophase begins when the nuclear envelope forms back again and chromosomes begin to unroll.

I hope you find this information useful and interesting! Good luck!
