Answer: Advantages: These locations are used to preserve different forms of plants and animals, both aquatic and non aquatic for a long time and to keep endangered species from going extinct.
Disadvantages: The proper facilities that would be needed for storing these animals could be very expensive. In other words, it requires alot of money. Secondly, animals and plants need to be properly tended to and this can be very time consuming.
Explanation:
Hello! Autotrophs make their own food (plants) and heterotrophs consume other organisms for energy (consumers.) Autotrophs use the process of photosynthesis to produce the oxygen as one of its products. Heterotrophs use the oxygen produced by the autotrophs to perform cellular respiration, which releases carbon dioxide that plants use; it's a balanced cycle. Hope this helps!
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Cells do need food. In a process known as cellular respiration, cells convert biochemical energy (oxygen as food) from nutrients into adenosine triphosphate (ATP), and then release waste products.
