The southern migration of which african people may have led to a significant increase in the incidence of malaria? a. bantu b. turkana c. masai d. efe

The answer is Bantu. They had already developed immunity to malaria due to exposure in their native environment. As they migrated southwards to conquer more land, they met the pygmies and the Khoisan. The Bantus had carried with them the malaria vectors. When the mosquitos infected the pygmies and the Khoisan populations, who had no immunity against malaria, the disease reduced their populations drastically hence enabling the Bantus to conquer their land.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
