A cell biologist carefully measured the quantity of DNA in grasshopper cells growing in cell culture. Cells examined during the

G2 Phase of the cell cycle contained 200 units of DNA. What would be the amount of DNA at G1 of the cell cycle in one of the grasshopper daughter cells

Answer:

100 units

Explanation:

The interphase of the cell cycle includes three stages: G1, S, and G2. During the S phase of interphase, the cell enters the process of DNA replication. DNA replication duplicates the existing DNA molecule and doubles the DNA content of the cell. The cell accommodates the newly formed DNA in two sister chromatids of chromosomes. If a cell of grasshopper contained 200 units of DNA in the G2 phase, the cell would have 100 units of DNA in the G1 phase. The S phase would have doubled the DNA content and the G2 phase had 200 units.

A thrombus (blood clot) in the first branch of the arch of the aorta would affect the flow of blood to the ________. A. left sid
seropon [69]

Answer:

C. right side of the head and neck and right upper arm

Explanation:

The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.

The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.

Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.

The map shows the distribution of wild boars in the United States (shaded area).
fgiga [73]

Answer:

Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.

Explanation:

The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.

According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..

About the other options:

  • <u><em>Wild boars were brought to the United States by humans</em></u><em>.  This is true, but it is not a fact that can be deduced from the information on the map.</em>
  • <u><em>Wild boars have quickly spread through the United States</em></u><em>.  The map does not show this information.</em>
  • <u><em>Wild boars have a high reproductive rate and no natural predators</em></u><em>. The map does not show this information.</em>

The ovarian cycle describes the monthly events of a post-pubescent ovary that causes a small number of primary follicles to grow
Damm [24]

Answer:

The ovarian cycle regulates endocrine tissue preparation, and egg release in female body.  

The first half of the ovarian cycle as the follicular process. Slowly growing rates of FSH and LH are causing follicle development on the ovary surface. This cycle makes the egg primed for ovulation. As the follicles develop they start releasing estrogens and low progesterone levels. Progesterone locks the endometrium in order to help ensure pregnancy. It takes about seven days to travel ovum through the Fallopian tube and to get implanted in uterus. There are 30-60 cells at this point of evolution, called the morula. If there is no pregnancy implantation the lining would be sloughed off. estrogen levels increase after around 5 days, and the menstrual cycle enters the proliferative process. The endometrium starts to regrow, replacing the weakening blood vessels and glands at the end of the last cycle.

<span>x - the time in weeks
y - the heights of the plants in inches

</span><span>When both plants to reach the same height, then yA = yB
