In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Hope this help
Answer:
DNA is a double helix and has base-pairing between nucleotides through the use of hydrogen bonds
Explanation:
The nucleotides are made up of a nitrogen base [base-pairing adenine (A) with thymine (T) and guanine (G) with cytosine (C)], a phosphate, and a deoxyribose (sugar); all of which are held together by hydrogen bonds. The binding allows the DNA to have a sugar-phosphate backbone connected with hydrogen bonds because they are firm but also easy to break (for DNA transcription)
Answer:
Part 1:
Correct option is A: "NaDP+/NaDPH"
Part 2:
Correct option is F: "glucose 6-phosphate dehydrogenase"
Explanation:
Various levels of control are put in place to keep a check on the pathway. This is an example of one such control. This dehydrogenase enzyme is responsible to control the rate of reaction and it is stimulated by NADP+ while it is inhibited by NaDPH. The oxidative reaction is under the influence of the NaDP+/NaDPH concentration, which is catalyzed by glucose 6-phosphate dehydrogenase.
Hope that answers the question, have a great day!
A Ribosome is not a membrane bound organelles
Most organisms can tolerate a very narrow pH range close to neutral, i.e., around pH 7. It is likely that there would not be much life in the lake at pH 3. Once the pH increases to above 5.5 to 6, it is more likely that life would begin to survive. Once the pH rises to above around 9, the solution is starting to become basic, and once again, few organisms will survive.
