I think the 4 major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes. The most commonly used vectors are plasmids.

A jet stream forms high in the upper troposphere between two air masses<span> of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
</span>.
.
So "Differences in temperature between two air masses" is the answer
Answer:
the answer would be A
Explanation:
Animal cells are oval and egg shaped so we can cancel out c and d
A is the correct answer because we can see green dots within the structure. Chloroplasts contain a green pigment called chlorophyll. This green pigment makes the chloroplast and the structure green (as we can see in the picture). Photosynthesis occurs in the chloroplasts, and it is where the plant gets its glucose from

The answer is option B "temperature." Greenhouse effect is the process of trapping the suns heat in the lower atmosphere. A increase of greenhouse effect would cause surface temperatures to rise. Which then contributes to global warming because of melting the ice bergs in cooler areas on Earth and causing waters to rise and creating storms. It's not option A because the sun gives off heat or harmful radiant waves which doesn't increase carbon dioxide levels. Wouldn't be option D because it would contribute but it wouldn't happen without a increase of temperature. It also wouldn't be option C because oxygen isn't relevant in this case.
Hope this helps.
