Answer:
If the electron transport system did not work, electrons from PSII would not be transferred to PSI. Ferredoxin would then have no electrons to transfer to NADP+ so NADPH would not be produced. This would also affect the light-independent reaction of photosynthesis because NADPH is needed in this reaction.

Edgenuity's Answer.
Answer:
C.
Explanation:
Every DNA nucleotide pair will consist of one pyrimidine and one purine. Due to the chemical structures of the different bases, adenine (A) will always bind with thymine (T) and guanine (G) will bind with cytosine (C). The same is true for RNA except that A always pairs with a close relative of thymine, uracil (U).
Answer:Plants - cell wall forms.
Animals - cleavage furrow forms
Explanation:Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells.
In plants , this occurs when a cell wall forms in between the daughter cells.
In animals , this occurs when a cleavage furrow forms. This pinches the cell in half.

Option: (A), (C) and (D)
<u>Explanation:</u>
- The Great Acceleration refers to the humanity’s impact upon the Earth’s geology and its ecosystems caused by continual and surge in growth of human activity.
- It was first recorded in mid-20th century and is continuing to this day. The 'invention of agriculture', advancement in medical technology which reduced the death rate, rapid increase in use of 'fossil fuels', 'fertilizers' and other resources contributed to global changes.
- Agriculture allowed us to produce more food and population increased rapidly.
- Fossil fuels created a surge in production of Green House Gases and global temperature began to rise.
