Answer:
In case of plants surface tension help to support the transpiration pull.
Explanation:
Surface tension is a force that hold the molecules in the surface to minimize the surface area.
During evaporation of excess amount of water from the stomata of leaves of plants by transpiration a surface tension is generated.
The generated surface tension helps to maintain the water column within the xylem tissue by the absorption of water from the soil by the roots.

Answer:
D. Waste management issues
Explanation:
Answer A: The five major types of pollution - water pollution, air pollution, land pollution, light pollution, noise pollution - have negative effects on the environment, on human health, and our planet as a whole.
Answer B: Urban Heat Island (UHI) is an urban area that is significantly warmer than its surrounding rural areas due to human activities. UHI decreases air quality.
Answer C: The increased use of surrounding land is the main cause of biodiversity loss.
Answer D: Any field of environmental management help people to solve pollution problems. So, D is the correct answer.

Copper has a higher activity than hydrogen and cannot replace it.
Copper has a lower activity than hydrogen and cannot replace it.
The reaction cannot occur because water is a reactant.
answer is Copper has a lower activity than hydrogen and cannot replace it.
Answers
Answer: Option (c) is the correct answer.
Explanation:
It is known that a stronger element is able to displace a less stronger element in a chemical reaction.
And, according to the reactivity chart hydrogen is more reactive in nature than copper.
Therefore, when Cu is added to then there will be no reaction because copper is less reactive than hydrogen.
Thus, we can conclude that the reaction not proceed to a product because copper has a lower activity than hydrogen and cannot replace it.

The equivalency of the frequency of the radio wave in Hz is .
The frequency of a wave is number of cycles of the wave at a given period of time. The frequency of the wave is directly proportional to the speed of the wave and inversely proportional to the wavelength.
where;
v is the speed of the wave
f is the frequency of the wave
λ is the wavelength
The given frequency of the wave = 650 kHz
The equivalency of the frequency of the radio wave in Hz is calculated as follows;

650 KHz means 650 thousand hertz = 650,000 Hertz. If it were an FM station, say at 92.3 MHz, that would be 92.3 Million Hertz or 92,300,000 Hertz. MHz means mega hertz. Mega = Million.
