What about transport you might ask well
in plants, how does a Redwood, one of the tallest trees in the world, move water from the soil to the needles on its tallest branches over 300 ft in the air? (That’s over 30 stories high!) Or how does a carrot transport the sugars made in its green, leafy tops below the surface of the soil to grow a sweet, orange taproot? Well, certain types of plants (vascular plants) have a system for transporting water, minerals, and nutrients (food!) throughout their bodies; it’s called the vascular system. Think of it as the plant’s plumbing, which is made up of cells that are stacked on top of one another to form long tubes from the tip of the root to the top of the plant. To learn more about it, let’s study the stem.
The answer is <span>They both suggest that snakes evolved from an ancestor with legs.
The second choice is not correct since we have no information about pythons and other snakes. We only have the relationship between geckos, snakes and legless eels. So, it is said that </span><span>snakes in general have more DNA sequences in common with four-legged geckos than they do with legless eels. This means that snakes are closer to geckos than the legless eels. We cannot conclude from this information which evolved from which, but we can say that </span><span>snakes evolved from an ancestor with legs.
In different case, if the snakes had more DNA sequence in common with legless eels, we would conclude that the snakes evolved from an ancestor without legs.</span>
Answer:
Deforestation leads to the loss of biodiversity and of indigenous tribes’ homes. Deforestation also affects billions more people around the world indirectly, through its impact on climate change, water and nutrient cycling and food availability. The world’s benefit from conservation far outweighs the costs to the owner, such as the profit they lose by not logging. It would thus make sense for the wealthier North to simply pay the tropical countries in the South to conserve and protect their forests.

Answer:
As Jane exercises her heart rate and breathing rate increase because he muscles are asking for more oxygen and get rid of more carbon dioxide. More blood is diverted towards the muscles as they need more oxygen for respiration. She needs to burn glucose with oxygen and water to produce energy so she can run. The way she can get this oxygen into her body is through her lungs. Where oxygen from the air diffuses into the blood and carbon dioxide diffuses out.
