Answer:
All natural soils are heterogeneous mixtures because no two nature soil samples will have the precise proportions of its inherent components.
Explanation:
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
b. Gravitational constant
Explanation:
G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.
- The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".
Mathematically, the law is expressed as:
F = G
Where F is the gravitational force
G is the gravitational constant
r is the distance
m is the mass 1 and 2 bodies

Allan already had a heart attack and can try to prevent another one by changing the diet, exercising, or even quit smoking, but there are non-modifiable risks such as age, sex and generic heritage, so If Allan is over 40 years old, male or comes from a family with heart diseases, Allan needs to be extra careful because those factors cannot be changed no matter how the way of life is changed.
Lions have many other sources of prey so they would most likely still be alive. If we are excluding the existence of other animals, then lions would decrease in population after fourteen days (longest they can go without food).
