If pharmaceutical researchers want to learn how to keep cancer cells from dividing uncontrollably, which
approach are they most likely to try?
Interrupt some stage of the cell cycle, such as the formation of the spindle that separates chromatids.
Develop strong dyes that will be able to color the chromosomes for good visualization.
Provide dangerous levels of radiation to irradiate the
cancer cells in a human being.
Starve the cancer cells by starving the patients, thereby reducing chances of cell division.
Answer:
c
Explanation:
Chemotherapy i.e. use of drugs to destroy the cancer cells by inhibiting their growth and division. Therefore, option (A) of interrupting stages in cell cycle is correct.
What do you understand by chemotherapy?
Chemotherapy is a medication that employs strong chemicals to destroy rapidly developing cells in your body. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. There are several chemotherapy medicines available.
Taxol (Paclitaxel) and other drugs that poison microtubules and impede the mitotic spindle have been used extremely efficiently in chemotherapy. This prevents cancer cells from proliferating and kills them.
Therefore, pharmaceutical researchers uses drugs to learn cancer treatment. Option (A) is correct.

The largest known protein with the greatest number of amino acids is titin.
What is titin ?Titin or connectin is a largest protein in humans which is encoded by the TTN gene, having greater than 1 µm in length and it functions as a molecular spring responsible for the passive elasticity of muscle.
It consist of 244 folded protein domains connected by unstructured peptide sequences, when the protein is stretched, the domains will unfold.
Titin protein involve in the contraction of striated muscle and connected the Z line to the M line in the sarcomere, contributes to force transmission at the Z line.
It limits the motion range of the sarcomere during tension, so it involve in the contribution of passive stiffness of muscle, it is the third most abundant protein in muscle after myosin and actin.

Which of these is a scientific hypothesis about the growth of a plant? A Plants make a pretty decoration in the house. B It's fun to watch this plant grow. C Plants grow best when they are happy. D This plant will grow best in sunlight.
Answer:
D. Plants grow best in sunlight.
Explanation:
The other answers can't be scientifically proven, therefore they would not make a good hypothesis. A hypothesis is a statement that can be tested and verified.
Plant will grow best in sunlight. So, the correct option is (D).
What is the scientific hypothesis about the growth of a plant?According to the evolution-immunity hypothesis in ecology, fast-growing plant species should suffer more from herbivores and pathogens than slow-growing species. Tests of this hypothesis have focused on above ground plant tissues, herbivores and pathogens. This should also apply to route defense.
When the amount of fertilizer applied to the plants is increased, the growth which is the height of the plant increases. As the amount of fertilizer increases, plant growth increases.
Plant growth shall be considered as an increase in plant volume and/or mass with or without the formation of new structures such as organs, tissues, cells or cell organelles that grow in the presence of sunlight.
Thus, plant will grow best in sunlight. So, the correct option is (D).
