Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
- Crude oil is made up of different fractions of hydrocarbons.
- As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases.
- Components with short carbon lengths rises out from the column first and are cooled and extracted.
- The categories are thereby, classified based on differences in their boiling points.
The accumulation of mineral salts in irrigated land is called soil salination. One of the undesired effects of irrigation is soil salination. Irrigation water often contains some salt at varying levels. Salt is nasty to plants and does not make themn grow, so farmers have to deal with salination by flushing the soil with extra water to leach salts out. Proper soil management and monitoring of water table is necessary to reduce impact of salination to soil quality.
From what we know, we can confirm that an invasive species will be the one that when introduced into an environment, reproduces at a rate that harms the biodiversity of the local ecosystem.
<h3 /><h3>What is the harm of these species to ecosystems?</h3>
Invasive species harm ecosystems greatly. Though invasive species are often rare, they cause great harm to ecosystems by affecting the biodiversity of the system and can lead to widespread extinctions of other organisms in that particular ecosystem.
Therefore, an invasive species will be the one that when introduced into an environment, reproduces at a rate that harms the biodiversity of the local ecosystem.

Answer:I’m not sure About natural selection but the relation of biology and evolution is the adaptation of other species through the years for example it has been a theory that the grizzly bear an black bear descended from the polar bear when a number of polar bears started living in warmer areas they had trouble living in there new environment because they were made for the cold but after many years of living there their offspring started to have different quality’s that made them more suitable to survive the environment like different colored fur and different claws this can be considered a form of evolution
