Dominance hierarchies

Musya8 [376]

Answer:

The correct answer is option B. likely give dominant males and females a reproductive advantage .

Explanation:

Dominance hierarchy is a social hierarchy in which members of a group of animals interact with each other to form a ranking system or superiority and inferiority of the organism. In such social groups, members have to compete for access for the food and resources which are limited.

Mating is also decided on the basis of the dominance of males and females in such social groups. Dominant male-female have always advantage for mating in comparison to lower members in the ranking.

For instance, female baboon mated to a dominant male or high ranked male so she can get high rank as well for the time of period.

Thus, the correct answer is option B. likely give dominant males and females a reproductive advantage .

Explain why in osmosis, water moves from an area of low solute concentration to and area of high solute concentration.

Lana71 [14]

Answer:

In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides. MORE water will move up the concentration gradient, thus there is a net flow up the gradient.

Examining rocks that form on either side of the Mid-Atlantic Ridge provides evidence of plate movement that supports the theory

elena-14-01-66 [18.8K]

Answer:

floor rocks were also symmetrical on both sides of the ridge, with the youngest rocks near the center and the oldest rocks farther away. This suggests that new rocks form at the center of ridges and then move away in the opposite directions.

What do these terms hydrophilic and hydrophobic mean and how do they relate to the structure of a cell membrane?.

Anarel [89]

Answer:

hydrophilic- attracts water

hydrophobic- repels water

Explanation:

A cell membrane is a bilayer of phospholipids. They have a hydrophilic phosphate heads, and hydrophobic fatty acid tails.

so in the cell membrane they would arrange like this:

The heads are point outwards as they attract water, and tails inwards as they repel water.

Hope this helps!

If the a and b loci are 20 m.u. apart in humans and an A B/ a b woman mates with an a b/ a b man, what is the probability that t

Elanso [62]

Answer:

The probability of having a Ab/ab child is 10%

Explanation:

The genes A/a and B/b are linked and 20 m.u. apart.

<u>The parental cross is:</u>

<h2>♀ AB/ab X ♂ ab/ab</h2>

<u />

<u>Gametes:</u>

The man only produces 1 type of gametes, so the probability of him producing an <em>ab </em>gamete is 1.

The woman produces 4: two parental (<em>AB </em>and <em>ab</em>) and two recombinant (<em>Ab, aB</em>).

Man: ab

Woman: AB, ab, Ab, aB

<u>The formula to relate genetic distance with recombination frequency is: </u>

Genetic Distance (m.u.)= Recombination Frequency X 100.

<u>Replacing the data in the formula, we have:</u>

20 m.u. / 100 = Recombination Frequency

0.2 = Recombination Frequency

Because the Recombination Frequency is 0.2, the woman will generate recombinant gametes 20% of times, and parental gametes the other 80%. <u>Each </u>recombinant gamete will appear in 10% of the cases, and <u>each </u>parental gamete will appear in 40% of the cases.

<u>The probailities for each possible genotype of the progeny resulting from that cross will be:</u>

Parental: AB/ab 40%

Parental: ab/ab 40%

<u>Recombinant: Ab/ab 10%</u>

Recombinant: aB/ab 10%
