1. What are some special structures within a cell?2. What is step three in the scientific method (explain the process)

3. Do cells make up all living things? (Use CER for this question)

Answers

Step 3: State your hypothesis

The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables. The hypothesis should relate back to your original question and must be testable.
1. What are some special structures within a cell?

Answer:
different types of cells have different structures but I’m going to assume this is on animal cells. The cell has tons of special structures, but some simpler ones are; nucleus, cell membrane, ribosome, cytoplasm, mitochondrion. I’ll attach a diagram!

2. What is step three in the scientific process

Answer:
The scientific process is as follows
1. Observation
2. Question
**3. Hypothesis**
4. Experiment
5. Conclusion
6. Result

3. Do cells make up all living things? (Use CER for this question)

Answer:
Yes they do!

From my understanding CER is cite, explain reasoning. I don’t know if your teacher provided you with material to cite but you should probably use your class textbook or any other recent class reading. Here’s a graphic organizer for your written answer

Cite: [quote from the text with page number]

Explain: explain why cells make up all living things, using the quote as evidence.

Reasoning: explain how the text connects to your claim.

ΝWhich compound is a metabolic intermediate of the light-independent reactions in photosynthesis?
ОАТР
PGA
RuBP
NADPH

Answers

3-PGA is the important metabolic intermediate in light independent reactions of photosynthesis.

PGA

Explanation:

Light-independent reaction in photosynthesis is called Calvin cycle and the reaction doesn’t directly require sunlight. But it still needs the products of light reaction. In light-independent reaction carbon dioxide is fixed from inorganic  form into an organic form.

In the fixation each molecule of carbon dioxide reacts with RuBP and forms two molecules of 3-PGA at a time. The reaction is catalyzed by the enzyme RuBisCO. Since 3 molecules of RuBP are involved a total of 6 molecules of 3-PGA will be formed in fixation.

Here the 3-PGA is the intermediate and in the next stage it will get reduced to G3P(Glyceraldehyde -3 phosphate).

Answer:

PGA
