A population of mammals leaves an ecosystem because of increased temperatures and decreased rainfall. what’s the reason for this

Serga [27]

The reason for the shift of mammals from the ecosystem due to increased temperatures and decreased rainfall is the change in the abiotic factors of that region.

Ecosystem is defined as how the living species of an area interact within themselves as well as the with the abiotic factors of the region.

Abiotic factors are the non-living things present in an area. These are the soil, mountains, temperature, sun, water, etc. The livelihood of a species in an area is influenced by both the living as well as the non-living factors. For example, if an organism can survive only in high rainfall then low amount of rainfall will be unfavorable condition for it to survive and grow efficiently.

Which of the following samples will have the greatest volume at STP?a. 22 g Neb. 22 g Hec. 22 g O2d. 22 g Cl2 e. All have the sa

sammy [17]

Answer:

22g of He

Explanation:

Volume of gas at STP is given as :

Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹

In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.

Number of moles = $\frac{mass }{Molar mass}$

Now, let us obtain the molar mass of the given atoms and elements:

For Ne; molar mass is the atomic mass = 20gmol⁻¹

He = 4gmol⁻¹

O₂ = (16 x2)gmol⁻¹ = 32gmol⁻¹

Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹

Number of moles of Ne = $\frac{22}{20}$ = 1.1mol

Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³

Number of moles of He = $\frac{22}{4}$ = 5.5mol

Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³

Number of moles of O₂ = $\frac{22}{32}$ = 0.688mol

Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol

Number of moles of Cl₂ = $\frac{22}{71}$ = 0.3099mol

Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³

What needed to happen before life could exist on Earth?

Dmitrij [34]

Answer:

The condition of the Earth had to become favourable before it could support any form of life.

The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.
