You have a population in hardy-weinberg equilibrium for the m and n alleles. These alleles are codominant. The allele frequency
pishuonlain [190]

You have a population in hardy-Weinberg equilibrium for the m and n alleles. These alleles are codominant.  Allele frequency of m is 0. 4. 0.48 is the frequency of heterozygotes in the population.

An allele frequency has been computed by dividing the total quantity of copies of each of the alleles at that specific genetic location in the population by the number of points of time the allele of interest has been observed in a population.

The frequency of each genotype is typically calculated by dividing the population's total count of individuals by the number of people who have that genotype.

When NADH passes its electrons into the Electron Transport System, NADH is chemically:
erik [133]

Answer:

Option D, oxidized

Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron).

Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.

Hence, option D is correct

Read the Mungo Lady and Mungo Man Do others in the field of anthropology agree with Dr. Thorne's view? Explain.
sweet [91]
I've read the story back a couple months ago

Actually, there are many archeologists and anthropologists disagree with dr. Thorne's view. Basically, Thorne strongly believes that what many calls Homo erectus was, in fact, Homo sapiens, and that they migrated out of Africa almost 2 million years ago and dispersed throughout Europe and Asia. That would actually be very different from what scientists have always believed about the evolution of the species. That is why many of them are against him)

I hope I helped :)
