Answer:
Options B, C, and D
Explanation:
The following assertions are accurate about the continental crust:
Its thickness ranges from 25 to 70 km.
It comprises various kinds of rocks.
This layer contains silicate minerals rich in sodium, potassium, aluminum, and calcium.
Answer: Determining clear boundaries for a system is challenging because one must grasp specific concepts involved, such as boundaries and environments that can be either advantageous or detrimental. An illustrative example might be the OpenLearn course, which covers Computing & IT.
Explanation:
Yes, the statement is indeed true.
Answer:
The word that is missing is Depletion.
Explanation:
Depletion of coral reefs can happen as a result of excessive fishing. The demand for fish increases alongside the growing population rate.
One consequence of unsustainable and unmanaged fishing is that certain fish species may be overfished, potentially leading to extinction.
This creates an ecological disruption, which hastens the decline of the Coral Reef.

Answer:
The light-independent reactions initiate with carbon dioxide and culminate in glyceraldehyde-3-phosphate (G3P). Energy from ATP and NADPH generated in light-dependent reactions is utilized for this process.
Explanation:
Step 1: Carbon dioxide combines with ribulose biphosphate (RBP) to create a six-carbon sugar, which quickly breaks down into two molecules of 3-phosphoglycerate (3-PGA).
CO₂ + RBP ⟶ 2 3-PGA
Step 2. A phosphate group is added to 3-PGA, forming 1,3-bisphosphoglycerate (1,3-BPG).
3-PGA + ATP ⟶ 1,3-BPG + ADP
Step 3. NADPH facilitates the reduction of 1,3-BPG to G3P.
1,3-BPG + NADPH ⟶ G3P + NADP⁺
Most of the G3P is converted back into RBP, although some exits the cycle to form glucose.
