<h3><u>Answer;</u></h3>
Distillation
<h3><u>Explanation</u>;</h3>
- Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation.
- Distillation is the process of separating components of a mixture based on different boiling points.
- To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected.
- It is applied in processes such as purification of alcohol, desalination, crude oil refining, and making liquefied gases from air.
D i believe i’m sorry if this is not correct if not try c
I HOPE that 1, 2, or 3 helps you!! :)
Answer:
1. The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... If large predators are present, they represent still higher trophic level and they feed on carnivores to get energy. Thus, the different plants and animal species are linked to one another through food chains.
Explanation:
2. When organisms use organic matter for cellular respiration, ALL the matter goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat (which is ultimately radiated out into space). So matter cycles, energy flows through ecosystems.
3. The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Answer:
The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.
