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.

kenny6666 [7]

Answer:

Estimated size is 1600

Explanation:

Given data:

Size of lake is 250 hectares

Total number of trout who netted is 400

Total number of trout in next week is 200

Total number of trout having fin clip 50

estimation population size is estimated by mark rupture as follow

Estimated population size = \frac{(marked\ initally \times total\ recaptured)}{mark\ recaptured}

Estimated size= \frac{400\times 200)}{50}

Estimated size is 1600

Give an example in the human body of a molecule cotaining ionic bonds
Lemur [1.5K]
<span>An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.
</span><span>
Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.</span>
DNA<span> - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.</span>
