Answer:
Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
- So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change.
- We should not kill any animal.
- We should decrease the use of plastics.
Answer: how a virus differs from a cell...
It doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion.
It doesn’t have any sort of metabolic enzyme of its own. So, no nutrition system is seen.
It can’t reproduce itself, without any help of the host living cell.
It can be crystallized, centrifuged or diffused.
It doesn’t have any sort of somatic development.
Chemically, its just a fusion of protein and nucleic acid. So, this characters differ a Virus from a living cell.

Answer:
19.32L
Explanation:
Given parameters:
Volume of the gas at STP = 29.3liters;
Using this information first, let us find the number of moles of the gas.
Number of moles = 
With the number of moles, we can further solve this problem;
Number of moles =
= 1.31 moles
More parameters;
Pressure on gas = 1.39atm
temperature = -23°C = -23 + 273 = 250K
Unknown:
Volume of gas = ?
Solution:
The ideal gas equation is the perfect fix to solve this problem.
It is mathematically expressed as;
Pv = nRT
where P is the pressure
v is the volume
R is the gas constant
n is the number of moles
T is the temperature
Input the parameters;
1.39 x V = 1.31 x 0.082 x 250
V = 19.32L
Answer:
(A)
Explanation:
High pressure has nothing to do with expiration(breathing out).
