The frequency of the sickle cell allele in areas where malaria is introduced will increase and it will be advantageous.
When a person is heterozygous for sickle cell anemia, it means it has one abnormal allele of the hemoglobin beta gene but doesn’t express the disease (like homozygous person).
On the other hand, a person heterozygotes for sickle-cell trait has a selective advantage in environments where malaria is present.

Answer:
A. Actin filaments and microtubules
B. intermediate filaments
Explanation:
Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.
Answer:
A protist
Explanation:
In the given question, the characteristic of an unidentified organism are given which are:
1. The organism is unicellular and autotrophic which means that it is a producer and belongs to a plant like organism.
2. The membrane bound nucleus means that the organism is an eukaryote.
The organism is thus an unicellular, autotrophic and an eukaryote could be a species of algae which is considered a protist. The protists are the organisms which shows characteristic of the ukaryotes but are not considered true plants and animals.
Thus, a protist is correct answer.
Answer:
You should probably use the third picture to support that your hypothesis was incorrect.
Explanation:
I do not know what your project was, but it seems as though you were able to gather that the state of matter is liquid throughout the experiemnt using the last picture. If your hypothesis was that the state of matter would change, then the third picture would show that this is wrong, as it remains in a liquid state.
