Answer:
C. ATP is required to move substance A into the cell.
Explanation:
As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".
This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.
<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>
Hence, the correct answer is "C. ATP is required to move substance A into the cell."

- <em>See attached image for the diagram of being referred to</em>
Answer/Explanation:
In the diagram showing a typical food chain in an ecosystem, <em>the arrow that connects the sun to plants represents the flow of radiant energy</em>. The sunlight produces radiant energy, of which producers, such as plants, converts into chemical energy through photosynthesis.
The <em>next arrow linking the plants to the rodent shows the flow of chemical energy</em> in plants to primary consumers, such as rodents, who feed on them.
Also, rodents, when preyed upon by secondary consumers, such as wolfs and owls, pass on the same chemical energy to them. So <em>the arrows connecting the rodent to owl, and to the wolf both show the transfer of chemical energy</em> from the rodent to the owl and wolf.
The next arrow shows the <em>transfer of thermal energy from the wolf to the environment</em>, as the wolf release heat from the body resulting from daily functions it performs, and also, <em>thermal energy is released to the surroundings as heat during the decomposition </em>of the body of an animal.
The <em>arrow linking the wolf to the decomposer which break down the body and waste of the wolf represents transfer of chemical energy to the decompose</em>r, as they break chemical bonds to obtain the energy they need to survive and grow.
Whale shark reproduction can be by laying eggs that is also called oviparity where the female deposits eggs in the algae or rocks. The embryos formed inside the eggs and feed on the yolk. They can also reproduce through viviparity which means by giving birth just like mammals wherein they are born fully formed. This reproduction process is through the placental link to the eggs wherein the yolk sac grows within a placenta that is connected to the wall of the uterus and gives the offspring the nutrients vital for their growth. Another reproduction process is through Ovoviviparity where eggs are formed inside the mother where the eggs hatch within the oviduct of the female and the young feed on the egg yolk of the yolk sac and the fluids that the walls of the oviduct secrete since the mother does not provide any food directly. Once the eggs are ready, eggs hatch inside the mother and it pups keep getting food from their surroundings until they are fully developed. The number of their offspring and the length of the gestation periods varies according to the species. Probably a female of some species may have only two offspring, but some other species may have between forty and eighty. The small sharks have shorter gestation period compared to large species that last from three to four months or up to more than two years. The large ones reproduce every two years, while the little ones have offspring each year. This is why the reproduction process of whale shark is not known in detail.
