Answer:
Water is least dense at 0°C (freezing point)
Explanation:
A hypothesis mustn't be too detailed since you are about to take the experiment and not sure of the outcome so we have to stick with Light intensity has an impact on the rate of photosynthesis.
Hope it helps.
Answer:
The first one is the type of energy used
The second one Is the thermal energy transferred
Explanation:
<em>I</em><em> </em><em>hope</em><em> </em><em>this</em><em> </em><em>helps</em><em> </em>
If you were to compute this, Angle C should be equal to 100°.
In a triangle, all angles sum up to 180°.
In triangle ABC, where the m∠A =30° and m∠50°:
m∠A + m∠B + m∠C = 180°
30° + 50 + m∠C = 180°
80° + m∠C = 180°
m∠C = 180° - 80°
m∠C = 100°
The triangle should look like the picture attached.
The answer is respiration.
The burning of fossil fuels is known as combustion. It is often compared with cellular respiration.
The general equation of cellular respiration is:
glucose + oxygen → <span>water + carbon dioxide
</span>
The general equation of combustion is:
fuel + oxygen → <span>water + carbon dioxide
Both reactions involve breaking down of large molecules (glucose and fuel) using oxygen into water and carbon dioxide. In both reactions, chemical energy is transformed into more useful form.</span>
