In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa

Answers

Answer:

directional selection, stabilizing selection

Explanation:

Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.

Which of the following environmental parameters would be important to monitor in order to ensure sustainable logging?

A. The number of trees cut down versus number trees burned
B. The number of new trees planted to replace those removed
C. The number of trees needed to increase soil fertilization
D. The number of trees removed within a single species

Answers

Answer:

B. The number of new trees planted to replace those removed

Explanation:

Because to ensure that logging is sustainable, they have to sustain a certain ratio of trees cut down, to trees planted. D. The muber of trees removed within a single species could be right, but I think B is more right.

If you get this wrong you can blame it on me.

Answer:

If the sodium/potassium ion pump were to stop functioning, what would eventually happen to the concentration gradients of sodium and potassium ions across the membrane

Answers

Answer:

The correct answer would be - concentration gradient will reach to equilibrium.

Explanation:

If the Na+/K= ion pump stops working which is to pump the sodium and potassium ion across the cell membrane. The movement takes place in 3:2 ratio with the help of ATP.

Eventually, the concentration gradients of sodium and potassium would be equal and found equilibrium across the membrane. This equilibrium would be reached due to passive transport that occurs in either direction across the membrane.

What is the relationship between Distance and average number of species?

Answers

Answer: The relationship between species and distance is that more distance or space has more species and less space has less species.

It can easily be understood by taking the example of the island in such a way that the larger islands contains more species than smaller islands.

There are a diversity of species seen in a bigger islands, more in number and more in variety.

It is very important for the studying the various species and its conservation, protection and other factors.

What's the definition of absoulute dating

Answers

Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

Their chewy fruit worm has 18 segments.According to their ages, Crystal gets 12 segments and Alexa gets 6 segments. The ratio of thegirls' shares of the worm, 12 to 6, is equivalent to the ratio of their ages, 12 to 6. According to the rule, how would the girls share a 9-segment chewy fruit worm?Since Crystal's age is two times Alexa's age, Crystal gets twice as many segments as Alexa.The ratio of Crystal's segments to Alexa's segments is 12 to 6 or 2 to 1..
