C#
NITROGEN FIXING BACTERIAS ARE
prokaryotic microorganisms which are capable for transforming nitrogen gas to fixed nitrogen component
D#
THE COMPONENTS RENTER THE SOIL IN WHICH THEY R BROKEN INTO MICROORGANISMS THAT IS KNOWN AS DECOMPOSERS
Answer is: the part of an experiment that stays the same though out the experiment is constant.
<span>Constant is a quantity that does not change.
</span>Experimental variable<span>, which is the also part of an experiment, is affected by the experiment (have change).</span>
Answer: c)returned to the soil by rhizobium
Explanation:
The frequency of carriers of the albino allele in the
population is. If
To solve this problem, we need to consider the Hardy-Weinberg
equation which is the following:
p^2 + 2pq + q^2 = 1
where: p = frequency
of the "A" allele
q = frequency of the "a"
allele
In other words, p^2 refers to the frequency of the
homozygous(dominant) genotype AA, q^2 represents the frequency of the
homozygous(recessive) genotype aa, and 2pq represents the frequency of the
heterozygous genotype.
In the problem, if q = 0.01, and p = 0.99, then the
frequency of carriers is 2pq which then becomes 0.0099 x 2. Thus, the predicted
frequency of Caucasians in the U.S. who carry a single albino allele is 0.0198.
