What effect does the increased temperature have on the ecology and distribution of plant species
Aliun [14]

Hello!

Higher temperature affects plants’ growth especially in temperate crops like wheat. It reduces the growth of shoots and roots in plants. This, in turn, results in a substantial reduction in the overall height of the plant. High air temperature can lead to dehydration and scorched leaves.

In general, the increase of temperature would cause a damage in ecology of a certain area as most plants would not be able to adapt to this change. This, in turn, will affect the distribution of such plant species as they would die off unless placed in an environment with more favorable conditions.

how does codominance at the molecular level help to explain why evolutionary processes haven't resulted in the elimination fo th
Yanka [14]

Answer:

here.

Explanation:

Due to the prevalence of malaria in Africa, the allele for sickle cell anemia (HbS) provides a selective advantage. That's why it remains in the population.

A normal African person (HbAHbA), with normal haemoglobin, will not die of anemia, but will die of malaria.

An African person with sickle cell anemia (HbSHbS), with abnormal haemoglobin, will die of anemia.

A heterozygous African person (HbAHbS), with half of his red blood cells (RBCs) being normal and the other half being sickle-shaped, will neither die from anemia, nor malaria since the plasmodium will be incapable of completing its life cycle in the abnormal RBCs.

Thus heterozygous African people will grow, reproduce and pass on the HbS allele to the next generations.
