Answer:
Carbon dioxide increases temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth. However, warmer temperatures also stress plants. With a longer, warmer growing season, plants need more water to survive.

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale
Answer: The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Molecules of oxygen and carbon dioxide have no charge and pass through by simple diffusion. Polar substances, with the exception of water, present problems for the membrane. While some polar molecules connect easily with the outside of a cell, they cannot readily pass through the lipid core of the plasma membrane.
Explanation:
Answer: all of them apply to Darwin's concepts.
The following concepts related to evolution are:
Letter A
Letter B
Letter C
Letter D
Letter E
Explanation:
<em>1. Darwin defined evolution as descent with modification meaning that species change over time, give rise to new species and share a common ancestor. (letter A)</em>
<em>2. Since the natural selection is mechanism proposed bay Darwin for evolution, based on the fact that resources are limited in nature, organism with heritable traits that favor survival and reproduction tend to leave more offspring than their peers, causing to increase in frequency over generations. (Letter C and E)</em>
<em>3. Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. It depends on the environment and requires existing heritable variation in a group. ( Letter D)</em>
<em>4. Natural selection can be considered a mechanism of change since the suviving group will determine the caracteristics of the next generation. Moreover after several generations of selection, the population might be made up entirely different, according to the environment, the inheritage and improvement of the specie. ( Letter B)</em>
