Answer:
Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.
Explanation:
In a controlled experiment, impact of one independent variable is studied on the dependent variable.
Here in this study sunlight is the independent variable while the radish plant is dependent variable.
The researcher wants to study the effect of sunlight on radish plants when they are exposed to it and compare it to the effect created on radish plants that are kept in dark.
Hence option D is correct.
Answer: Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species. A limiting factor can be any biotic or abiotic factor: nutrient, space, and water availability are examples. The size of a population is tied to its limiting factor. The environment, what food is there and what predators live there. How much food they get and if they are decreasing from weather, predators etc.

Answer:
Veins.
Explanation:
Heart is the main organs of circulatory system that transport blood in the body.Human heart is four chambered and separates the oxygenated and deoxygenated blood in the body.
Arteries are responsible for the passage of blood from heart to the body parts. The deoxygenated blood from the body collect in the veins and transfer to heart. Arteries has high pressure than veins and veins are thinner than artery.
Thus, the answer is veins.
Answer:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
