In a population in which homozygotes (AA and aa) mate preferentially with individuals of the same genotype, which frequency will
uranmaximum [27]

Answer:

It will remain constant...

Explanation:

In accordance with the Mendel's law of segregation, independent assortment as well as Hardy-Weinberg Theorem., no matter what type of cross within the homozygotic characteristics takes place, the frequency of dominant and recessive will remain constant over the whole population even if selective breeding strategy is applied.

For example, the ratio for a single trait of allele will remain 3:1 for a whole population of large numbers

Of the following lists of electron transport compounds, which one lists them in order from the one containing electrons with the
notsponge [240]

Answer:

B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2

Explanation:

FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.

NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.

So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.
