Answer:
Only Photosystem I - 1, 5, 6
Only photosystem II - 3, 2
Both Photosystem I and II - 4
Explanation:
Only Photosystem I
a) Reduction of NADP+ - uses light energy to convert NADP+ to NADPH2
b) Reduction of electron transport chain between the two photosystems
c) Oxidation of electron transport chain between the two photosystems.
Only photosystem II
a) Oxidation of water - here the absorbed light energy is used to dissociate of water molecules to produces protons (H+) and O2 along with free ions
b)Reduction of primary electron acceptor - An electron is taken by pheophytin which is a primary electron acceptor molecule that is located within photosystem II and hence it get reduced.
Both Photosystem I and II
a) Light is absorbed in both photosystem I and II. While in photosystem I, light waves of large wavelength i.e 700 nm are absorbed, in photosystem II light waves of short wavelength of i.e 680 nm are absorbed.
Your answer is C. The pancreas produces enzymes that break down carbohydrates, proteins, and fats
Parallel circuits are circuits when placed in a parallel
position. Meaning that for each device, they have their own branch. The voltage
that is received in the circuit is equal to the individual devices. The total
current is equal to the current of each device. The resistance is the reciprocal
of the resistances of each device combined.
Given:
Device 1 = 12 ohms
Device 2 = 4 ohms
Voltage total = 40V
Required:
Current at 12 ohms
Solution:
40V = V1 =V2
Since V =IR
I1 = V1/R1
I1 = (40V)/(12 ohms)
<span><u>I1 = 3.334 A(Amperes)</u></span>
C.
The blood fluid contains less water, which will cause the water to go into the cells and make them swell up.
