Newton's third law of motion states that for every action in nature there is an equal and opposite reaction. This law is also known as action-reaction law.
Newton's third law of motion states that for each and every action (force) in nature there is an equal and opposite reaction. This says that forces always act in pairs they do not act independently. Action and reaction forces are the forces of equal and opposite magnitude, but they are not balanced forces because they act on different objects hence they don't cancel out each other.
For example, if an object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, the forces result from interaction between the two.

For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Answer:
Anaphase of mitosis
Explanation:
Taxol: is a drug that prevents growth of cancer cells by interfering with the disassembling process of microtubules during the Anaphase of mitosis. The drug is able to bind to microtubules and freeze them.
Microtubules: are filamentous proteins and are made up of tubulin subunits. Microtubulesform part of the cell's cytokeleton which is vital for maintaining the shape of the cell and transportation of organelles and other molecules inside the cell.
Anaphaseof mitosis: microtubules from opposite poles of mitotic cells attached at the kinetochore of sister chromatids pull the each sister chromatid to opposite poles thus pulling them apart. The disassembling of the microtubules causes the sister chromatids to pull apart.
The mitotic phase specifically metaphase is of the most interest to a researcher studying Taxol because this drug halts the process of mitosis by preventing microtubules from depolymerizing.
If you were a researcher studying Taxol, you would be most interested in the cells found in the mitotic phase of the cell cycle. Taxol is a drug that disrupts mitosis by binding to the tubulin in microtubules and preventing their depolymerization, which effectively halts the process of mitosis in metaphase. This is because during metaphase, the chromosomes line up along the metaphase plate of the cell and the microtubules attach to the centromeres of the chromosomes, preparing to pull them apart during anaphase. Since Taxol prevents the microtubules from shortening, they cannot pull the chromosomes apart, thus cells treated with Taxol get stuck in metaphase.

Answer;
-Crossing over and random independent assortment.
The two events that increase the genetic diversity of the daughter cells produced are crossing over and random independent assortment.
Explanation;
-During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments, which resulting to recombination that creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
-Additionally, when cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other, this results in gametes having unique combinations of chromosomes.
amoeba
paramecium
euglena
Answer:
paramecium is the correct answer.
Explanation:
A common protozoan that moves by cilia is the paramecium.
paramecia are the single-celled organism, they live in the aquatic habitats.
The whole body of the protozoan is covered by cilia.
Cilia is hair-like organelles that help the paramecium to swim in the water as they have streamlined structure.
The function of cilia in the life cycle of a protozoan is it help in locomotion and in food ingestion.
