Answer:

A (bean)

Explanation:

Leguminous plants are plants that belong to the family FABACEAE and characterized by their possession of pods as fruits and ability to form nodules in their root for a symbiotic relationship to occur between nitrogen-fixing plants. An example of these leguminous plants that can be found in the option is BEAN.

Bean plant like all other legumious plants host certain bacteria called NITROGEN-FIXING bacteria in their roots in order to help them convert Nitrogen gas into usable compound forms.

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.

What would happen to a plant cell in a hypotonic solution
mash [69]
<h2>Answer:</h2>

<u>When a plant cell is placed in a hypo-tonic solution It becomes turgid and hard.</u>


<h2>Explanation:</h2>

A hypotonic solution refers to a solution that has less solute and more water than another solution. When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
