Answer:

The answer is A

By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

natali 33 [55]
20 chromosomes.

A cell with 40 chromosomes going through meiosis will result in individual haploid cells with 20 chromosomes each.

After the first nuclear and cellular division in meiosis, each cell will already have 20 chromosomes each, since homologous chromosomes are separated at Anaphase I in Meiosis I. After the second nuclear and cellular division in meiosis, each cell will have 20 chromosomes as well, since the sister chromatids of each of the 20 chromosomes are separated during Anaphase II in Meiosis II.

Hope this helps! :)

A dihybrid cross can be described as a cross in which two traits are studies at a time. The alleles for each trait will assort independently. To depict the outcomes of a cross, a punnet square can be generated.

According to the scenario mentioned in the question 9/16 plants will have red, axial flowers. 3/16 plants will have red, terminal flowers. 3/16 plants will have white, axial flowers. 1/16 will have white, terminal flowers.

When i am in the anatomical position, is my ulna on the inside or outside?
Mashcka [7]
The anatomical position is defined to be the body standing upright with face and torso and feet directed forward and arms around 45 degrees away from the torso with palms facing forward. This is a standard reference in human anatomy, especially in describing body part relations (i.e. the 5th digit of the hand is medial to the umbilicus, etc.). The ulna, in anatomical position is inside or medial to the midline of the body.

<em>An easy way in determining where the ulna and the radius are is that the ulna is in line with the pinky finger and the radius is in line with the thumb. </em>
