B. Replication enzymes proofread new DNA strand before replication is complete
(C is 100% in accurate. You have millions of DNA in your body)
<span>The biosphere is simply "life on Earth"—the sum total, that is, of all living things on Earth. Yet the whole is more than the sum of the parts: not only is the biosphere an integrated system whose many components fit together in complex ways, but it also works, in turn, in concert with the other major earth systems. These and many other interactions make it easy to see why scientists speak of Earth as a system—and why some go even further and call it a living thing.
1.) </span><span>plants (biosphere) grow in the ground (geosphere)
2.) </span><span>The geosphere alone accounts for almost 82% of the combined mass of the four subsystems.</span>
The animal Darwin is describing is a tortoise. In the reading, there are quotes that imply that it is a tortoise such as:
“it was quietly pacing along”
“it would draw in its head and legs”
“I frequently got on their backs, and then giving a few raps on the hinder part of their shells...”
what might be this meaning of dis question?
Answer:
The "short tail" dominant allele is easier to eliminate by selective breeding.
Explanation:
The only way for a recessive allele to be expressed (be visible) is when it appears as recessive homozygotic. These means the organisms need to have 2 copies of the gene. Selective breeding is based on the characteristics that one can see, so if the organism shows the "dilute" phenotype you can keep reproducing this individuals and get rid of the dominant allele.
On the other hand if you have a population with the dominant phenotype, you discard all the ones that have a recessive trait and you breed the dominant phenotype you could still get individuals with the recessive phenotype and individuals that express the dominant phenotype but are heterozygous.
