Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
Weak acids do not and cannot dissolve in water. They become even more diluted, or watered-down, and become even weaker acids.
Answer: True
Explanation: When they burn they release a lot or big amounts of carbon dioxide it releases carbon dioxide into the air
Answer:
Option-D
Explanation:
Captive breeding or breeding in the captivity is the conservation technique employed by the government to conserve nature.
Captivity breeding is also known as the captive propagation of animals in which animals are kept either in their natural habitat (ex-situ conservation) or in artificial conditions like in zoos where condition similar to the habitat of animal are created.
The breeding programme aims at conserving the natural habitat of the animals to prevent the endangered species from extinction. The endangered species are at risk of extinction due to loss of fragmentation, pollution, predation and others.
Thus, Option-d is the correct answer.
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period.[1][2]
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[3]
