Malaria is spread by mosquitoes because females pick up a parasite and when they bite someone to nurture their eggs it spreads
Answer:
True
Explanation:
In a capitalist society, the poor make up the working class that is exploited through their work, generating income and profits for businessmen and tycoons, who continue to get rich and have their needs and desires completed and complemented by the work that the poor perform.
With this, we can confirm that within the capitalist society, wants are often supplemented for the poor, but only the wants of the rich and powerful, the wants of the poor end up being suppressed and often left aside.
Answer:
interaction between two different organisms living in close physical association, typically to the advantage of both.Compare with antibiosis.
a mutually beneficial relationship between different people or groups.
Explanation:
Answer:
a. The directionality of the complementary strand is antiparallel. The double-stranded DNA is antiparallel comprising two strands, which run alongside each other, however, point in reverse directions. In a double-stranded molecule of DNA, the 5 prime ends of one strand align with the 3 prime ends of the other strand, and vice versa.
b. The mediation of base pairing is done by non-covalent hydrogen bonds. It is reversible, that is, the strands can separate and can come combined again without any chemical modification.
The specificity of base pairing is illustrated by hydrogen bonds that is, the first strand produces hydrogen bonds only with a particular base in the second strand, and these two bases produce a base-pair.
c. The interaction or association of non-covalent type, that is, hydrophobic interaction and hydrogen bonding. Collectively, they both are strong. In the process, one base associate with the other base on the complementary strand.
d. The phosphate backbone possesses the tendency to associate with water on the outside of the molecule, and this is favorable chemically as both the strands are held together by hydrogen bond and hydrophobic interaction.
The polar molecules of sugar can produce hydrogen bonds with the surrounding molecules of water. The negatively charged phosphate group associate with the positively charged ions. The nonpolar nitrogen bases are found within the molecule and associate favorably through stacking interactions.
