B. Egg is the female reproductive cell. Hope this helped, Enjoy the rest of your day!!!!!!!!!!! :)
<span> The quantity of stomata compared between plants in tropical environments and plants in hot, arid climates is
</span> Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
because in tropical it has more stomata
so correct option i conclude is B
hope it helps
Answer: The correct answer is option C
FACILITATED DIFFUSION.
Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).
Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.
Answer:
In the ocean, carbon dioxide reacts with seawater to form carbonic acid, and this results in the ocean pH to drop (becoming acid). When carbon dioxide increases there will be an increase in carbonic acid, thus a huge drop in the pH level causing the water to be more acidic, resulting in the phenomenon called ocean acidification. Ocean acidification result in the oceans' animals inability to form shells and skeletons .
Explanation:
Ocean acidification causes a disruption the oceans' ecosystem,for corals and shelled-marine animals, acidifaction of their shells and skeletons ,make them vulnerable to harsh weathers (storms), and they make not fully recover. This phenomenon may also affect the reproduction and development of other marine animals.
Ocean acidification also have an effect on humans. We get our food from the ocean, and ocean acidification means a decrease in food supply. Due to the death of corals, the tourism sector will also be affected.
