Answer:
Survival of the fittest; nature "selects" the organisms best suited to their environment to survive and pass on traits. ... What role does the environment play in natural selection? Species adapt to fit their environment because a species environment is what selects for traits that are fit or less fit.
Answer:
<em>a) Alleles at one locus can hide or mask the effect of alleles at another locus </em>
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". Epistatic genes might be either recessive or dominant. When the epistatic gene is recessive, the interaction is known as "recessive epistasis". While when the epistatic gene is dominant, the interaction is known as "dominant epistasis"
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

Answer:
B) Krebs cycle (citric acid cycle)
Explanation:
Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.
Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
