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.

Answers

Answer 1

Answer:

c

Explanation:

Answer 2

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.

Glucose is the simplest monosaccharide which cannot be broken down further. Thus, option C is correct.

What is Glucose?

Glucose is the primary component of carbohydrates. Glucose is a monomer made up of carbon, hydrogen and oxygen. Molecular formula of glucose is C6H12O6.

The functional group in glucose is an aldehyde present at the first carbon atom.

Glucose is called monosaccharides because it cannot be hydrolysed further. It is the simplest carbohydrate also referred as simple sugars.

Glucose molecules are chiefly linked together forming a glycosidic bond by removal of water molecule and form a disaccharide.  

Glucose is chiefly produced by plants during the process called photosynthesis.

Glucose is the key component in metabolism. It provides energy to the body cells to carry out physiological activities. Glucose is found in blood.

Excess of glucose in the blood results in a medical condition called diabetes. It can be life threatening if not managed on time.

What would happen to a plant cell if it placed in water?

Answers

Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.

What term best describes region “B” of the phospholipid model above?

Answers

Answer:

Hydrophobic

Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.

The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.

What is phospholipid model ?

Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.

The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.

Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.

Hence the region marked as B is saturated and unsaturated fatty acids.
