Researchers who have studied color blindness and color deficiency have found that a total color blindness is extremely rare in a
Schach [20]

Answer:

Option-B

Explanation:

Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.

1. Total color blindness is not a rare disease in animals.

2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.

3. The red-green color blindness is more common than the blue-yellow color blindness.

4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.

Since all options except Option-2 are incorrect therefore option-2 is the correct answer.

Corn seed has more non-metabolically active storage material in
Over [174]

Answer:

The effect of the non-metabolically active stored material is that the seed will struggle to germination. As a result, it has to remove this stored sugar or materials, it will undergo a cellular respiration at a slow rate before metabolism resumes.

 What is the difference between a scientific theory and a scientific law?
Harman [31]
Scientific theory is what the scientist thinks is correct, but still has room for correction, while a scientific law is proven by experiments over and over again to deem it's correct.

A drug that prevents assembly of the mitotic spindle would cause the cell cycle to stall just after
noname [10]

Answer:

The correct answer will be option-A

Explanation:

Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.

The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.

This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.

Thus, option-A is the correct answer.

Two petri dishes of radish seeds are prepared as follows: a disk of absorbent, but otherwise inert, filter paper is placed in th
valina [46]
A. The increased biomass in the sunlit dish came from the carbon and oxygen atoms present in the carbon dioxide it took up during photosynthesis that it used to synthesize organic molecules.

Plants use photosynthesis in order to convert light energy (from the sun) into chemical energy, stored in carbohydrate molecules (such as sugars). This chemical energy can be further transformed to fuel some of the organism's activities. This chemical reaction (photosynthesis) is light-dependent and includes the use of carbon dioxide and water to produce sugars and oxygen. The seeds that were put on a sunny windowsill had plenty of light energy needed for their photosynthetic activity. This resulted in the accumulation of sugar molecules in the plant tissues and an increase in the biomass. These sugar molecules were synthesized by the carbon and oxygen atoms comprising the carbon dioxide molecules absorbed during photosynthesis.   


B. The most likely explanation for the why the dark-grown seedling lost biomass is that cellular respiration in the cells of the seedlings consumed the starch and oils present in the seed as sources of energy.

Plants use cellular respiration in order to constantly supply energy to their cells. This chemical reaction uses the sugar molecules produced by the photosynthesis and stored in the plant tissues to get energy. Seeds put in a dark cupboard did not have access to any light energy, therefore, they could not perform photosynthesis. As a result, they had to perform respiration and consume starch and oils which were present in the seed to get the necessary energy. This resulted in a reduction in their biomass.
