<h2>Answer:</h2>
The correct answer is option C which is The light reactions harvest ___ <u>energy____</u>, while the carbon reactions produce<u> __carbohydrates_____.</u>
<h3>
Explanation:</h3>
- The light dependent reaction is the first part of photosynthesis.
- In the light energy energy is captured and used to break a water molecule into hydrogen ans oxygen ions with free electrons.
- These electrons move into a electron transport chain lean to dark reaction.
- Energy from these electrons is used in the dark reaction to produce carbohydrates from the CO2 and H2O and energy from the light reaction.
4m/s²
Explanation:
Given parameters:
Velocity of the ride = 6m/s
radius of the ride = 9m
Unknown:
Acceleration of ride = ?
Solution:
We are going to solve this problem using the formula for centripetal acceleration:
Centripetal acceleration = ![\frac{[tex]V^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5DV%5E%7B2%7D)
}{
}[/tex]
V is the velocity
r is the radius
Centripetal acceleration = 
= 4m/s²

Answer: Increased pressure gradient
Explanation:
The movement of gas takes place by the help of diffusion. The pressure is established in between the two different types of gases.
The movement of gas from higher concentration to lower concentration will take place when a pressure gradient is established in between them.
So, if there is an increased pressure gradient between oxygen and carbon dioxide then gaseous exchange will take place.
