True
Phloem is used for the transport of minerals
Xylem is used for the transport of water
Answer:
As carbon dioxide concentrations increase, so too does the rate of photosynthesis until a certain point where the graph levels off. At lower carbon dioxide concentrations carbon dioxide is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis.

Answer:
A trait that is altered easily by small changes in diet.
Explanation:
The phylogenetic tree explains the evolutionary relationship between the organisms. The phylogeny of the organisms will depend on the difference and similarities in their genetic or physical characters.
The traits that are used in phylogeny must be constant and present in the ancestors or in atleast a group. The trait that can be easily modified or changed cannot be used for the study of the evolutionary relationship. Hence, trait which is altered by diet cannot be used in phylogenetic analysis.
Thus, the correct answer is option (C).
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
