Ans: maintain homeostasis
Homeostasis is any
self-regulating process by which biological systems tend to maintain stability
while adjusting to conditions that are optimal for survival. It is the stable
state of an organism and of its internal environment. Maintenance of
homeostasis usually involves negative feedback loops. These loops act to oppose
the stimulus, or cue, that triggers them. The stable condition is the condition
of optimal functioning for the organism, and is dependent on many variables,
such as body temperature and fluid balance, being kept within certain pre-set
limits.
Answer:
148
Explanation:
According to Hardy-Weinberg equilibrium,
p + q = 1
p² + 2pq + q² = 1 where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of homozygous dominant genotype
2pq = frequency of heterozygous genotype
q² = frequency of homozygous recessive genotype
Here,
Total population = 592
Number of NN people = 148
Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25
q = √0.25 = 0.5
p = 1 - q
= 1 - 0.5 = 0.5
Hence, p = 0.5
Frequency of MM genotype = p² = 0.25
Number of people with MM genotype = 0.25*592 = 148
Hence, 148 people will have MM genotype or M blood group.
<span>If each of the pairs of
chromosomes was heterozygous (what gives you the highest potential
number of different gametes), then the number of possible gametes
increases from 4 to 8 for a diploid organism. To figure out how many
are possible, raise the number of homologous chromsomes (2 for a diploid
organism) to the power of the number of chromosomes. So if you have
two different chromosomes (A and B), raise 2 to the 2nd power (or
multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C,
then you have 2^3, or 2 x 2 x 2 = 8.
To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc
gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>
One result of a loss of ground water would be that the freshwater on earth is 98 percent stored in the ground, therefore we would lose 98 percent of the very little amounts of freshwater we have
