During Hadean time, the solar system was forming within a cloud of dust and gas known as the solar nebula, which eventually spawned asteroids, comets, moons and planets. Astrogeophysicists theorize that about 4.52 billion years ago the proto-Earth collided with a Mars-size planetoid named Theia.

pav-90 [236]

Answer:

The true statement is option D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.

Explanation:

The distance between the sun and the Earth is one of the factors that determines the temperature of the planet. The energy from the sun travels to the Earth, increasing the temperature.

The other fact that has a role in the Earth's temperature is the concentration of oxygen in the atmosphere. It can increase or decrease the temperature according to the amount of this. Oxigen contributes to the greenhouse effect, which helps to keep the temperature in a range that allows life to happen.

It takes 88 years for a popuaiton to grow from 1,200 individuals to 4,800 individuals what is the instristic rate of growth?

Katen [24]

Answer:

3.43

Explanation:

Data provided in the question:

Time taken for the given growth in population = 88 years

Initial population, n = 1,200

Total population, N = 4,800

Now,

we know

Total population is given as:

N = n + [ rn( (k - n) ÷ k ) ]

here,

r is the intrinsic growth rate

k is the Carrying capacity = 2N = 2 × 4,800 = 9,600

on substituting the respective values, we get

4,800 = 1,200 + [ r × 1,200( (9,600 - 1,200) ÷ 9,600 ) ]

3,600 = r × 1,050

r = 3.43
