Ans. (C). stabilizing selection.

Stabilizing selection is defined as a variant of natural selection that stabilizes a particular trait in a population on an average trait value (non-extreme trait value). It favors individuals with intermediate variants, instead of individuals having extreme traits.

The females, which lay 4-5 eggs in each clutch, are showing an average or intermediate trait, while the females, which produce fewer or more eggs than this are showing extreme traits. Hence, individuals with extreme traits will show reduced fitness due to stabilizing selection.  

Thus, the correct answer is option (C).

Which process in eukaryotic cells will proceed normally whether oxygen (o2) is present or absent?
VLD [36.1K]
The correct answer is glycolysis. 

Glycolysis is an anaerobic process of splitting a molecule of glucose (6 carbons) to 2 molecules of pyruvate (3 carbons each). Glycolysis does not require the presence of oxygen and will still produce energy, albeit lower than aerobic metabolism. In the absence of oxygen, fermentation can occur wherein pyruvate is further converted into lactate.

sladkih [1.3K]

Answer:

A. maintenance of axons is not a cellular activity associated with microtubules.

Explanation:

Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
