Answer:
Explanation:Which of the following equations are balanced correctly?
2Ag2O → 4Ag + O2
Zn + HCl → ZnCl2 + H2
Cu + H2O → CuO + H2
2C4H10 + 13O2 → 8CO2 + 10H2O
Answer:
Option-A
Explanation:
In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.
In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.
Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.
Thus, Option-A is the correct answer.
Answer:
Diffusion sees molecules in an area of high concentration move to areas with a lower concentration, while osmosis refers to the process by which water, or other solvents, moves through a semipermeable membrane, leaving other bits of matter in its wake.
Answer: The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg called ovules. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
