The head will face the air because it is hydrophilic. The tails are hydrophobic
Answer:
Grana and stroma
Explanation:
Photosynthesis is the process by which plants make their organic food. This process occurs in the chloroplast of the cell. Grana and stroma are the two parts that are involved in photosynthesis.
Grana are stacks of thylakoid which increase the surface area for light absorption. It is the place where light-dependent reaction occurs. Stroma is the fluid that surrounds grana. It contains the enzyme which is required in photosynthesis. It is the place where light independent reaction occurs.
Stroma is the place where synthesis of organic material from carbon dioxide and water occurs. Therefore the correct answer is grana and stroma.
Answer:
1. Chlorophyll absorbs light
2. Water split to start electron transport chain
3. ATP produced
4. ATP used to build glucose form carbon dioxide
Explanation:
Photosynthesis is the process whereby green plants synthesize their food (glucose) in the presence of sunlight. This photosynthetic process occurs in two major stages viz: light dependent and light independent phases.
In the light dependent phase, the following occurs sequentially:
- Chlorophyll absorbs light energy from sun
- The energy is used to split water molecule in a process called PHOTOLYSIS OF WATER in order to start electron transport chain.
- The electron transport chain yields ATP and NADPH, which will be used in the next phase.
In the light independent phase, also called, CALVIN CYCLE, ATP is used to power the formation of glucose from carbon dioxide
Final velocity after 5 sec is 16 m/s
<u>Given that;</u>
Initial velocity = 4.5 m/s
Constant acceleration = 2.3 m/s²
Time taken = 5 second
<u>Find:</u>
Final velocity
<u>Computation:</u>
Using first equation of motion;
v = u + at
v = 4.5 + (2.3)(5)
v = 4.5 + 11.5
v = 16 m/s
Final velocity = 16 m/s
