Explanation:
The student most likely observed both <u>(A) Vacuole</u> and <u>(C) Chloroplast</u> that led him to the conclusion, that the cell is a plan cell.
<u>Reason :</u>
In a plant cell, <u>Vacuole</u> occupies 70% to 90% of the total volume of the cell, making it easier to identify.
Chloroplast contains photosynthetic pigment called chlorophyll (green in colour), which is only found in plant cell.

Answer:
Natural science can be divided into two main branches
Explanation:
life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, astronomy and Earth science.
Answer:
50 mol CH₄
Explanation:
The question is incomplete so I looked it up online.
<em>How many moles CH₄, are needed to produce 50 moles of CO₂?</em>
Step 1: Write the balanced equation for the complete combustion of methane
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CH₄ to CO₂ is 1:1.
Step 3: Calculate the number of moles of CH₄ needed to produce 50 moles of CO₂
We will use the previously established molar ratio.
50 mol CO₂ × 1 mol CH₄/1 mol CO₂ = 50 mol CH₄
