Nucleic acids carry this information because they help make DNA
Answer:
Larger islands that are large and close to the mainland are shos lower rate of extinction due to the fact that the species present have more space so there will be more resources available in comparison to smaller islands where limited space and limited resources available.
Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.
Answer:
50%
Explanation:
According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.
The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.
Selective logging—the practice of removing one or two trees and leaving the rest intact—is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape.
