What factors influence gene flow between populations? 1. Differences in animal behavior and life history strategies can form eff

ective barriers to gene flow. 2. The home range size of the species. 3. Reproductive barriers must involved anatomical differences that prevent mating. 4. Barriers to gene flow between populations are always physical geographic barriers.

Answer:

All these factors affect gene flow:

1. Differences in animal behavior and life history strategies can form effective barriers to gene flow.

2. The home range size of the specie can also serve as a barrier to gene flow.

Explanation:

Firstly, gene flow is the transfer of genetic traits from one population to another. It is an important process for transferring genetic variations from one population to another.

There are several barriers or factors that limit or increase this gene flow.

Gene flow can be affected by mobility or rate of dispersal. It is expected to be lower in species with low mobility which is the movement from one place to another or low dispersal and vice versa. So a population with a shorter home range size can't effective aid gene flow as they interact only with individuals of the same population and vice versa.

Gene flow barrier could be by physical barriers which is the isolation of a geographical location preventing them from exchanging genetic materials with the same species of the sane population.

This type of physical barrier is usually but not always natural.

Barrier to gene flow could be reproductive preventing transfer of genectic materials due to differences in mating period, season of birth and so on.

Another barrier could be difrerneces in customs, ethnicity, religion and clans.

All these factors affect gene flow but the 3rd and 4th option are not totally true as barriers to gene flow are not totally physical geographical barriers and not totally anatomical differences but also soil preference and other factors.

Thanks.

Which of the following represents the number of premolars in deciduous dentition of teeth in humans?
hammer [34]

The correct answer is E. 0

Explanation:

The deciduous dentition or baby teeth refer to the first set of teeth human have before the permanent teeth, these teeth are prevalent during infancy and include 20 teeth: 4 central incisors, 4 lateral incisors, 4 canines and 8 molars divided into 4 primary molars and 4 secondary ones. In the case of premolars, these are part of permanent teeth but not of deciduous teeth as they only appear after deciduous teeth begin being replaced and these replace the molars in deciduous dentition. Thus, the number of premolars in deciduous dentition in humans is 0.

During , the cell's nucleus duplicates itself and the cell divides. During , a specialized form of cell division occurs to form
mr Goodwill [35]

a specialized form of cell division occurs to form egg and sperm cells : Mitosis, Meiosis, Fertilization

What is Fertilization?

During fertilization, the main nucleus of an embryo is formed by the combination of a paternal sperm nucleus and a maternal egg nucleus. In reality, the process of fertilization in all organisms involves the union of the genetic material from two gametes, or separate sex cells, each of which has half the number of chromosomes that are typical for the species. In microorganisms and protozoans, the earliest type of fertilization involves the transfer of genetic material between two cells.

The fusing of the two gametes' membranes, which results in the creation of a channel that allows material to go from one cell to the other, is the first critical event in fertilization.

(a) if the seawater carbonate ion concentration is 270 ?mol/kg, what is the approximate rate of calcification, and approximately
Travka [436]
Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.

Using this calcification rate,
30 = 20 * 1 * days

days = 1.5

The deposition will require 1.5 days.
