The human activities directly or indirectly affect the nature. The deforestation and the removal of the vegetation for the purpose of development or timber, the land is exposed to the dangers of the landslide. The tress, plants and other vegetation keeps the soil in place with the help of their roots. The soil erosion is prevented by the trees, but the cutting down of them by the humans increases erosion and hence, the risk of landslide.
Recycle and renew are the two R's that uses and transforms the waste material. Recyclables do not equate to renewable as recyclable materials do not occur naturally.
<h3>What are recyclable and renewable?</h3>
Recyclable is the resources that are used finite times over and over and undergo a certain process for re-use purposes. They can be naturally or by humans, processed to be used again.
Renewable is resources that are natural and are replenished in nature when gets decreased by natural processes.
Some recyclables like aluminum and glass are not renewable as they are not formed naturally and do not get replenished by natural processes.
Therefore, recyclables are not renewables.

Answer:
A) species with short reproductive cycles
Answer:
The three types of symbiotic relationship are: mutualism, commensalism, and parasitism.
Example: 1.Mutualism: Pistol shrimps and gobies.
2. Commensalism: Sharks and Remora Fish.
3. Parasitism:. Tapeworms, fleas, and barnacles.
Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by 
x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>
= 10 generations
<u>New bacterial population</u>
Using formula<u> </u> x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
