Answer:
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
Answer:
A. 2 speciation events and 5 extinctions
B. 5 speciation events and 1 extinction
Explanation:
As we can see from the diagram, there were only 2 ,aim speciation events for lineage A. The extinction events were 5 for the A lineage. Hence, as the extinction event was more rapid than the speciation event so lineage A contains only one species.
On the other hand, the diagram shows that for lineage B there were 5 speciation events and just 1 extinction event. Hence, the number of species in lineage B were more at the time zero as just one extinction had occurred.
Answer:
B
Explanation:
<em>Respiration </em><em>can </em><em>happen</em><em> </em><em>without</em><em> </em><em>sunlight</em><em>,</em><em>but </em><em>photosynthesis</em><em> </em><em>cannot</em><em>.</em><em>a</em><em>n</em><em>d</em><em> </em><em>photosynthesis</em><em> </em><em>doesn't</em><em> </em><em>take</em><em> </em><em>place </em><em>at </em><em>night</em><em>,</em><em>so </em><em>less </em><em>carbon dioxide</em><em> </em><em>is </em><em>used </em><em>up </em><em>than </em><em>it </em><em>is </em><em>produced</em><em>.</em>
