Answer: 1, 2, 4 are accurate.

Explanation:

1. Joe is on a hill (on a trail) above the ocean. The beach and ocean are at similar altitudes. Therefore Joe is at a higher altitude than if he was at the beach.

2. Since Joe is on a hill, he has a higher altitude than at sea level. Air at a higher altitude has lower density because there is less air "ontop" of itself than at lower altitudes. As well, his hill is above the ocean, which means there is a lot of water, making the air more humid than where he is. Humidity also makes air denser.

4.The air pressure will decrease if Joe goes up to higher altitudes because there will be less air on top of itself.

Alborosie

Answer:

The correct answer is - B. lower environmental availability of CO2

Explanation:

In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4  to avoid photorespiration.

These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.

Fofino [41]

<u>Answer:</u>

<em>B. Many genetic diseases would be curable. </em>

<u>Explanation:</u>

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.
