Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.
Answer:
b. hibernation to lower metabolism in the winter
Explanation:
Tundra, besides the one I live in apparently, are very, very dry because of the cold. This means that it may be helpful to hibernate for the part of the year where it is even too cold for plants and other animals.
C
The definition of geologists is someone who studies the EARTH and its structure, how it's made etc.
The moon is not part of the earth so it is c.
The given question is incorrect. The correct question is:
Which of the following is true about a plant with the genotype AABbcc?
a. It is heterozygous at two loci.
b. It is homozygous at two loci.
c. It is triploid.
d. It will not express the recessive c allele.
e. It has recessive alleles at three loci.
Answer:
b. It is homozygous at two loci.
Explanation:
When an organism has two identical alleles of a particular gene, it is said to be homozygous for that gene. The given genotype "AABbcc" has a dominant allele for "A" and the recessive allele for "c". It is homozygous for these two genes but is heterozygous with respect to "B". The presence of three complete sets of chromosomes makes the organisms triploid. The given genotype carries two alleles for each gene and therefore, it is diploid.
Explanation:
As lineages invade different niches and become isolated from one another, they split, regenerating some of the diversity that was wiped out by the mass extinction. The upshot of all these processes is that mass extinctions tend to be followed by periods of rapid diversification and adaptive radiation.
