Hello. Giraffes with longer necks survive compared to those with shorter necks because of natural selection. Over time, natural selection favors the traits that would make a species thrive better in the environment. Giraffes with short necks won't have access to that much food compared to those with long necks thus they eventually died out.
ANSWER: natural selection.
I think it is C as plants take in Co2 and release oxygen which humans use to breathe.

Quantitative measurements are those that deal with a quantity, for example:
Mass of as sample
Length of a piece of wire
Molecules in a mole
Volume of a gas
Temperature of a sample
These types of measurements are called Extensive.
Qualitative measurements are those that deal with the quality, for example:
Color of a sample
Texture of a surface
Coarseness of a powder
Aroma of a reaction
Malleability of a metal
These types of measurements are called Intensive.
<h3><u>Answer;</u></h3>
<u>Latitude</u>
The principal characteristic that differentiates temperate and tropical rain-forests is <u>latitude.</u>
<h3><u>Explanation;</u></h3>
- There are two types of rain-forests, namely, the tropical rain-forests and the temperate rain-forests. These two types share some similarities such as being rich in plant and animals species with a greater diversity in tropical rain forest.
- However they differ in a number of ways; tropical rain-forests are warm and moist; while temperate rain-forests are cool.
- <u><em>Tropical rain-forest, forested areas must: Lie between the Tropic of Cancer and the Tropic of Capricorn, receive rainfall regularly throughout the year, remain frost and free through out the year with little fluctuations.</em></u>
