Clear-cutting a rainforest will result to deforestation. It will result in the suffering of the animals in the rainforest and eventually death of the animals. It will destroy the ecosystem in the forest. Some animals will also be extinct because their natural habitat is destroyed. The deforestation rate in Brazil was once the highest in the world. Destroying large areas of rainforest per year. About 600,000 km^2 of the Amazon rainforest was deforested.
Answer:
B) Heterozygotes are less susceptible to the malaria parasite, so there is an advantage to being heterozygous.
Explanation:
Sickle cell anemia is a recessive condition in which the red blood cells (RBCs) become sickle shaped. Due to the abnormal shape they are not able to transport oxygen efficiently which proves lethal for the person. Both, homozygous dominants and heterozygotes survive.
However in African countries with high rate of malaria, heterozygotes are selected over the dominant homozygotes. Dominant homozygotes have all normal RBCs which make them susceptible to malarial parasite since RBC is the host cell for it.
Heterozygotes produce some normal RBCs and some sickle shaped. Malarial parasite is not able to attack sickle shaped RBCs because of its unusual shape. So heterozygotes are less susceptible to malaria. Since they also have some normal RBCs, they are not affected much by sickle cell anemia too. Hence, heterozygotes evade both sickle cell anemia and malaria and heterozygous is the most advantageous genotype in this case.
