What best describes the relationship between the two sets of reactions of photosynthesis, which are the light-dependent reactions and the light-independent reactions?
Answer:
The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions.
Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.
What are Light-dependent and independent reactions?Light-dependent reactions which convert light energy into chemical energy, so the goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to form ATP and NADPH, while these two energy storage molecules occur which is used in light-independent reactions.
Light-dependent reactions occur in the thylakoid membrane that use light energy to make ATP and NADPH while in light-independent reactions or the Calvin cycle where electrons activated from light-dependent reactions provide energy to make carbohydrates from carbon dioxide molecules.
Thus, Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.

How do scientists explain the slow rotation of the sun with respect to the rest of the solar system?
Answer:
The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun's equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential rotation" is an area of current research in solar astronomy.

A plant is an example of a heterotroph. True
False
Answer:
False
Explanation:
Heterotroph means energy is made through consuming another organism.
Autotroph means energy that is made through producing by itself.
A plant makes energy by itself
So a plant is an autotroph, so this statement is false.

Three red square pieces of wood, four yellow square pieces, and five blue square pieces are put into a cloth bag. Four red round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
The question is incomplete. Here is the complete question.
Three red square pieces of wood, four yellow square pieces, and five boue square pieces are put into a cloth bag. four re round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
What are the chances that the piece is red round or blue round piece?
a. Cannot be determined
b. 1 chance out of 3
c. 1 chance out of 21
d. 15 chances out of 21
e. 1 chance out of 2
Because:
a. 1 of the 2 shapes is round
b. 15 of the 21 pieces are red or blue
c. There is no way to tell which piece will be picked
d. Only 1 of the 21 pieces is picked out of the bag
e. 1 of every 3 pieces is a red or blue round pieces
Answer: b. 1 chance out of 3
e. 1 of every 3 pieces is a red or a blue round pieces
Explanation: Inside the bag, there will be:
Total of squares: 3 + 4 + 5 = 12Total of round: 4 + 2 + 3 = 9Total of pieces inside the bag: 12 + 9 = 21The question is asking for a round red piece. The probability of that happening is
P(r) = [tex]\frac{4}{21}[/tex]
And a blue round piece:
P(b) = [tex]\frac{3}{21}[/tex]
It is a "OR" probability, so:
P(r or b) = [tex]\frac{4}{21} +\frac{3}{21}[/tex]
P(r or b) = [tex]\frac{7}{21}[/tex] or [tex]\frac{1}{3}[/tex]
Which means 1 out 3 pieces taken out of the bag will be red or blue.

What is the second velocity of the car with two washers at the 0.50 meter mark?
m/s
(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
