Individuals who are heterozygous for the sickle-cell allele suffer less from the attack of malaria because a small percentage of the red blood cells are sickle-shaped. They are more resistant to malaria than individuals who have two copies of the normal haemoglobin allele. Heterozygous individuals have a better chance of surviving and reproducing in regions where malaria is prevalent since they do not fully contract the disease.
Answer:
The answer is - Biomass decreases as energy is transferred from one level to another.
Explanation:
The options are;
A. Chipmunks and insects can occupy the same niche.
B. As the number of bears in this community increases, the number of chipmunks will increase.
C. Insects are classified as omnivores in alpine meadow communities.
D. Biomass decreases as energy is transferred from one level to another
The answer is D. Biomass decreases as energy is transferred from one level to another
The energy pyramid being referred to is in the attachment below.
Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
D. The octupus population would decrease.
This is because if more sharks were in the ecosystem than they would feed on more octopus, decreasing the population of them.
DNA probably. It might be one of the latter rungs too, thymine, and 2 others I forgot
Answer:
Phoebus Levene.
Explanation:
Two types of nucleic acids are DNA and RNA. The monomers of mucleic acid contains the pentose sugar, nitrogenous bases and the phosphate group attached with the bases.
Friedrich Miescher was the first scientists who discovered the nucleic acids. He identified the nucleic acids from the bandage that contains the nuclei of white blood cells. The new compounds discovered is known as nucleic acid. But the monomers of the nucleic acids was first explained by Phoebus Levene. Different forms of nucleic acid was also postulated by Phoebus Levene.
Thus, the answer is Phoebus Levene.
