People homozygous for the sickle-cell anemia allele develop a life threatening disease, while those homozygous for the normal allele are at the highest risk of dying from malaria. carriers have some resistance to malaria, but do not develop sickle cell anemia. this is an example of

Stabilizing selection.

Explanation:

Stabilizing selection may be defined as a type of  the natural selection the mean population is stabilizes on the particular non extreme trait of a population.

The people with heterozygous condition for sickle cell trait are selected against the malaria condition. These organisms survive whereas the homozygous dominant for the normal trait and homozygous recessive dies due to malaria. Here, the heterozygous genotype individual are selected and shows the type of stabilizing natural selection.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

b because they naturally adapt to their environment plz mark brainliest
