Have cones as reproductive structures.
Have vascular tissue.
Answer:
The answer is:
B. Worms consuming the blood from mammals.
Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).
Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).
Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).
The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.
Hope this helps! :)

Answer:
B. Every point on the line is an equivalent ratio.
C. As the line goes up, the speed increases.
D. Simone can pick any ratio on the line and she will be swimming at a rate of 2 mph.
Explanation:
If the line on the graph has equivalent ratio, it shows that the Simone swim at the speed of 2 mph. If the line on the graph goes up , it means the speed of swimming increases while when the line on the graph goes down, the swimming speed decreases so maintaining the speed of 2 mph, the line have to go horizontally in straight line. If Simone can pick any ratio on the line present on the graph so she has to swimming at a rate of 2 mph.
Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
