Question

The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection?
Directional selection
Stabilizing selection
Disruptive selection

Answer 1

i think its stabilizing selection

Answer 2

G6PD deficiency is an inherited condition in which the body doesn't have enough of the enzyme glucose-6-phosphate dehydrogenase, or G6PD, which helps red blood cells (RBCs) function normally. G6PD deficiency is most common in African-American males. Many females are carriers. It is known that Africa and the Mediterranean basin are high-risk areas for the infectious disease malaria. Researchers have found evidence that the parasite that causes malaria does not survive well in G6PD-deficient cells. How can you explain this?
Natural selection favors G6PD deficiency as compared to malaria.
Genetic drift is responsible for greater occurrence of G6PD deficiency in these regions.
Somatic mutations lead to G6PD deficiency in malaria-inflicted regions.
