How do hydrogen bonds between molecules explain why they are polar?​

Biology
1 answer:
valkas [14]2 years ago
6 0

Answer:

The attractive force between water molecules is a dipole interaction. The hydrogen atoms are bound to the highly electronegative oxygen atom (which also possesses two lone pair sets of electrons, making for a very polar bond. Hydrogen bonds are very strong compared to other dipole interactions.

in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?
JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.

Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the
brilliants [131]

Answer:

The correct answer is: positive feedback.

Explanation:

Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance <u>inhibits</u> its producer that is called <u>negative feedback</u>. On the other hand, when a substance <u>stimulates</u> its producer to keep secreting said substance, this is called <u>positive feedback</u>.

Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).

Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.

Describe the two fields of study comparative and molecular
levacccp [35]
The anatomy (Comparative Anatomy) chart contains the ones that say " compares the limbs of different organisms" and "compares fossilized structures to living organisms".
The cells (Molecular Biology) chart contains the ones that say "compares the genomes of different organisms" and "compares cells of organisms".
If this is for Plato there should be a chart that has one column for anatomy(Comparative Anatomy) and one for cells(Molecular Biology). Hope this helps.
