Why could earth not support life if it was a smaller planet?

Biology
1 answer:
lara31 [8.8K]3 years ago
6 0

<u>Answer</u>:

Smaller planets would dissipate heat more rapidly and this criteria doesn't satisfy the conditions of existence of life.

<u>Explanation</u>:

The existence of life on Earth was possible because it fulfilled the criteria needed for the conditions of generating life in a planet. Its distance from sun is appropriate, it is made up of rock, it is big enough to have a core which is molten and it has a magnetic field. If it was a smaller planet, then it would have a liquid hot core that dissipate heat at a rapid rate. This condition doesn't support the criteria of life's existence.

Suppose you had 4.0 moles of solute dissolved into 2.0 liters of solution. what is the molarity
Vitek1552 [10]

Answer:

M

2.0

m

o

l

L

−

1

Explanation:

The molarity,

M

of this solution can be calculated by a formula which is;

M

=

n

V

where;

M

= Molarity of solution

n

=Number of moles of solute

V

= Volume of solution in Litre

Given,

n

=

4.0

moles and

V

=

2.0

L, so we have enough information to calculate the molarity of the solution;

M

Why are populations, rather than individuals, the units of evolution?
dimulka [17.4K]

Explanation:

The unit of evolution is the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. This means that most mating takes place within the population.
