Answer:

He developed the theories of gravitation in 1666, when he was only 23 years old. Some twenty years later, in 1686, he presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis." The laws are shown above, and the application of these laws to aerodynamics are given on separate slides.

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.

Consider two cells: a stomach-lining epithelial cell dividing more than twice a day and a liver cell dividing every year or two.

dalvyx [7]

The correct answer is liver cell is likely to be in G0 phase.

Cells of inner lining of the stomach made of epithelial cells. They are protective in nature. They get damaged and need to be replaced through division. Whereas, liver is made of hepatocytes and once they reached maturity. These cells are not need to be replaced and cell cycle is generally in G0 stage. The G0 phase is a resting phase in the cell cycle. In this phase cells remain in a quiescent state because in G0 phase a cell is neither dividing nor preparing to divide. G0 phase allows cells to become adapted for particular function. Hepatocytes may divide when there is removal of part of liver.

Which term describes this example? A rabbit's cells have two sex chromosomes that are different.

il63 [147K]

D) male

Most mammals use the X and Y system to determine sex.
Males have 1 X chromosome and 1 Y chromosome while females have 2 X chromosomes.

The question states that there are 2 different sex chromosomes, so this rabbit must be male.
