A reference to the Sun! The chemical reaction that results from the energy of light leads the molecules of water and carbon dioxide to disintegrate and then reassemble into molecules of glucose and oxygen gas. After the sugar is created, the mitochondria convert it into energy that can be used for growth and repair. Thus, option B is correct.
Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun. Glucose is used by plants as a fuel source and to make substances like cellulose and starch.
Cellulose is used to build cell walls. Starch is preserved in seeds and other plant parts for use as a food source.
Therefore, The sun provides the plants with the energy they need to develop and prosper. The plants would not be able to survive if it were always dark outside.

Activators
Centrioles
Vacuoles
Answer: Activators
Explanation:
Inhibitor is a substance that slows down or prevents a particular chemical reaction.
Activator is a substance that stimulates or initiates a chemical process.
Centriole is an organelle that helps in cell division, or make copies of themselves. Centrioles are only found in animal cells.
Vacuoles are strong central storage compartment in organisms.
Answer: Hydrotropism
Explanation: Hydro means water and tropism means moving in a positive orientation by the organism.The movement of plant in the response to the higher humidity is known as hydrotropism.
The process starts with the root cap movement that sense water and sends signals to the roots for elongation.
Example: plants moving towards higher humidity.
b. The theory states that pressure is inversely proportional to volume.
c. The theory assumes that particles are in random and continuous motion.
d. The theory states that pressure increases with temperature.
Answer:
A
Explanation:
Answer:
Insulin is secreted by the pancreas which regulates the blood glucose level in the blood. Insulin generally reduces the blood glucose level by depositing the glucose in the liver and muscles as glycogen.
In diabetic people, enough insulin is not produced by the pancreas as a result glucose level increases in the blood which is called hyperglycemia. So in this condition, insulin injection is given from outside to increase the level of insulin in the blood.
Then this increased level of insulin helps in reducing the extra amount of insulin from the blood by accumulation it on the liver. Therefore insulin play a role in reducing the extra amount of free glucose from the blood.
B.) chloroplasts
C.) cytoplasm
D.) genes
Ans. (D). genes.
Gene represents a sequence of DNA, which codes for a functional molecule (such as RNA or protein). Information about inherited traits is stored and transferred through the genes.
Heredity occurs due to genetic material, which gets passed from parents to their progeny in the form of DNA. During reproduction, all the information for survival, growth, and reproduction, found in the DNA gets transferred to the next generation.
Thus, the correct answer is option (D).
