<h2>Answer:</h2>

Air is homogeneous mixture

<h2>Explanation:</h2>

Pure air is a homogeneous mixture which is made up of nitrogen and oxygen. Its elements are not actually separated from one another. But the composition of air is not uniform and may be effected by environmental factors, such as industrial pollution, heavy forestation or volcanic activity. In that case it can become heterogeneous mixture too

I don't remember this all that well but if I am thinking properly, it should be option C because Air is 2 oxygen molecules. That is what a homogeneous mixture is correct?

How is the phloem in a leaf related to the roots of the plant?

Answer:

The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.

Which of the following scenarios is an example of temporal isolation?
DedPeter [7]

Answer:

B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.

Explanation:

Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.
