Answer:
1.
Nearly all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium.
In what is called radioactive emission of "alpha particles" the atom of, say uranium, spits out particles in the form of two protons and two neutrons--a helium nucleus.
2.Helium is obtained through natural gas as it is extracted from the ground. The helium is a result of the decay of thorium and uranium. As these elements decay, they release an alpha particle. That alpha particle is the nucleus of a helium atom.
3.Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.
Explanation:
The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
The effects can be encountered to other organisms when each organism is destroyed in a food chain that consists of green leaf, slug, shrew and fox.
<h3>What are the effects of destroying organism in the ecosystem?</h3>
Yes, effects likely to be encountered when each organism is destroyed in a food chain consists of green leaf, slug, shrew and fox because every organism in the ecosystem depends on the other organism for their survival.
So we can conclude that the effects can be encountered to other organisms when each organism is destroyed in a food chain that consists of green leaf, slug, shrew and fox.

Answer:
Allele frequency for brown fur color
Allele frequency for orange fur color
Explanation:
Given
"O" denotes dominant brown allele
and "o" denotes recessive orange allelehe
The trait "coat color" is linked with X gene
Brown homozygous females: 30
Brown heterozygous females: 75
Orange females: 10
Brown males: 50
Orange males: 65
Allele frequency for orange color
Thus
Allele frequency for orange fur color
Allele frequency for brown color
Allele frequency for brown fur color
