Answer:
1. replication
2. gene
3. strand polarity
4. translation
5. complementary base pairing
6. chromosome
7. antiparallel
8. transcription
9. allele
Explanation:
1. Replication is the process by which DNA is duplicated or the process of making another copy of DNA.
2. Gene is the physical unit of heredity i.e a segment of DNA transferred from parents to offsprings. A gene also encodes a useful products such as protein.
3. A DNA strand is a polar molecule, which is attributed to the phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA.
4. Translation is the process whereby the information in a mRNA molecule is used to synthesize a protein.
5. Complementary base pairing is a phenomenon whereby Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).
6. A chromosome contains of single long molecule of DNA coiled together around histone proteins. The chromosome is associated with different types of proteins.
7. In the double-stranded DNA molecule, one strand runs from 5' to 3' and the other runs from 3' to 5'. This is called ANTIPARALLEL nature of DNA.
8. Transcription is the process by which a DNA molecule is used to synthesize a mRNA single strand.
9. Allele is the alternative or contrasting form of a gene. Each allele is contributed by each parent
It depends on the particular ecosystem and why and how it was destroyed. It can take just 2 years or over 100 years depending on the different factors. Sometimes ecosystems never recover.
The answer is K-selected.
<span>The population size of K-selected species is fairly constant
in time, unlike the population size of r-selected species. r-selected species
are usually bellow carrying capacity and the population size is density
independent. On the contrary, K-selected species are usually near or at
carrying capacity and the population size is density dependent. It can be concluded that sperm whales have K-selected populations, since they </span><span>maintain their populations close to carrying capacity.</span>
Answer:
The closed circulatory system considerably enhances the speed, precision, and efficiency of the circulation. The blood flows far more rapidly and it takes less time to circulate through the closed system and return to the heart.
