Answer:
are scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. A biosphere is the term used to describe the combination of every ecosystem on the planet. Our biosphere is Earth. The biosphere includes all living beings and their relationships. Changing temperatures can alter which organisms can survive in an ecosystem. Plants create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage global warming .Biotic factors pertain to living organisms and their relationships. Abiotic factors are the non-living components of the ecosystem, including sunlight, water, temperature, wind, and nutrients. Ecologists use biotic and abiotic factors to predict population changes and ecological events. A biome is the term used to describe organisms that occupy a certain area. Biomes are determined by the primary vegetation type, the climate of the area, and the geographic location. The plants and animals in a biome share common traits that are specific to the individual biome those plants and animals inhabit.
Explanation: I
had a similar question on edg so I jut gave you the answer I put on their I'm sorry if it so wrong
Correct option - B
Two two organelles are :
- Organelle A - Chloroplast
- Organelle B - vacuoles
Because, Chloroplasts are the special organelles present in only plant cells. and vacuoles are smaller in size in animal cells as compared to the plant cells.

Explanation:
Answer:
24555 years
Explanation:
Data provided in the question:
Half life of carbon 14 = 5700 years
carbon present in the dead man = 5% of the original amount of carbon 14
Now,
let the initial Amount of carbon be 'A'
Therefore,
after half life
Amount of carbon =
Thus,
=
here,
k is the decay constant
t is the time = 5700 years
therefore,
1 =
or
0.5 =
taking natural log both the sides
-0.69314 = 5700k
or
k = - 0.000122
therefore,
for dead man Amount of carbon = 5% of A = 0.05A
thus,
0.05A =
or
0.05 =
taking natural log both the sides
we get
-2.995 = - 0.000122 × t
or
t = 24555.18 ≈ 24555 years
