P (purple) and p (white) are the dominant and recessive alleles for flower color in peas. Similarly, A (axial) and a (terminal) are the dominant and recessive alleles for flower position in peas. Two plants with the genotype PpAa are crossed. Which genotype is indicative of white axial flowers?

Answers

so you do the gene chart,

         P       p

A    PA     Ap

a    Pa      ap


So "ap" would make it white but not axial.  "Ap" is white and axial. That is your flower. :) hope I helped.

The answer is D- An ovum is a sex cell. If it contains a mutation, this mutation may be passed from parent to offspring. Only mutations on gametes may be passed from parent to child. This is because these cells use during sexual reproduction.

A class of chemical called a neurotransmitter is important in the transmission of nerve impulses. Neurotransmitters are packaged by the cell into small, membrane-bound sacs called vesicles. Upon receiving a chemical signal, the vesicles move toward the plasma membrane and fuse with it, releasing the enclosed neurotransmitters from the terminal end of the nerve cell. Which organelle is most likely responsible for packing neurotransmitters into a vesicle?

How can photosynthesis be related to cellular respiration?

Answers

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

When atoms transfer one or more electrons to or from other atoms, the atoms involved are called ____.

Answers

In chemical bonds, atoms can either transfer or share their valence electrons. In the extreme case where one or more atoms lose electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond.

A cell model with a circle containing four vertical pairs of lines attached at the middle, stacked in two rows of two is a correct illustration of metaphase I for a 2n = 4 cell (Option g).

What is metaphase?

Metaphase is a step in mitosis which is characterized by the alignment of homo-logous chromosomes.

  • Homo-logous chromosomes are chromosomes having the same or nearly identical sequence.

  • During metaphase, homo-logous chromosomes are located at the equatorial plate of the cell.

In conclusion, a cell model with a circle containing four vertical pairs of lines attached at the middle, stacked in two rows of two is a correct illustration of metaphase I for a 2n = 4 cell (Option g).

Answer:

g. A cell model consisting of a circle containing four vertical pairs of lines attached at the middle, stacked in two rows of two.

Explanation:

In Metaphase I of the cells, homologous chromosome pairs are lined up next to each other which is defined as synapsis. Each pair of two chromosomes (bivalents) consists of four chromatids in total are positioned on the metaphase plate.

Metaphase I occurs when tetrads of chromosomes are lined up along the equator of the spindle. Spindle fibres are attached to the centromere region of each homologous chromosome pair. These homologous chromosomes consist of the matching alleles originating from mother and father.

In Metaphase I, meiotic recombination (''crossing over'') happens. Meiotic recombination means there is a genetic shuffling of the attributes of both parents. A result is a large number of possible genetic combinations. It is estimated that there is a 50-50 chance for the daughter cells to receive or mother's or father's homologous for each chromosome. In an organism with 2 sets of chromosomes, there are 4 ways in which the chromosomes may be arranged. This is resulting in differences in the chromosomal distribution in daughter cells after meiosis I.

Which of these conditions made it beneficial for aquatic plants to move onto land?

Answers

Not knowing what the choice of conditions is, I would say that it would be very damp conditions on land, and if the plant photosynthesises it would be good because of 'purer' sunlight. but if show what the choice of conditions are I can give you a more accurate answer (hopefully)
Sunshine, and damper areas. If it's aquatic it probably lives in water, so have damp swampy ground could help.
