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.
2. Identify two functions of plastids in plant cells.
Plastids. Plant plastids are a group of closely related membrane-bound organelles that carry out many functions. They are responsible for photosynthesis, for storage of products such as starch, and for the synthesis of many types of molecules that are needed as cellular building blocks.
Write in the Functions of Each Organelle Describe the function of each organelle. Nucleus carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. Ribosome Endoplasmic reticulum Golgi apparatus
Answer:
Explanation:
Ribosome works with ribonucleic acid to produce a functional protein. Translation takes place at the ribosome.
The endoplasmic reticulum helps in transport of proteins that are made by the ribosomes and folds them into sacs that are called cisternae from where it is moved to the Golgi apparatus.
Golgi apparatus served as store house for molecules that moved from endoplasmic reticulum. They are then released from the Golgi apparatus in what are called secretory vesicles into the cytoplasm.
Answer:
See the answer below
Explanation:
The nucleus is a double membrane organelle that is responsible for controlling the activities of the cell. It contains the DNA which carries the gene and the hereditary information of the cell.
The nucleoli are small spherical structures that are located within the nucleus which function in the formation of the ribosome and hence, important for protein synthesis in the eukaryotic organisms.
The ribosomes are structures within the cell which represent the site of protein synthesis. During protein synthesis, the mRNA and the tRNA attach themselves to the ribosome to form the translation complex for the initiation of protein synthesis.
The Golgi apparatus is a system of membrane responsible for the packaging and secretion of proteins and lipids within the cell.

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.

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.

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.
What is the first velocity of the car with two washers at the 0.25 meter mark?
m/s
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
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s

Will the CO2 molecules that exist today still be the CO2 molecules in a million years
Answer:
Yes
Explanation:
cause nothing is created or lost it is just cycled.
Yes, the carbon dioxide molecules existing today will be the same carbon dioxide molecules in a million years because the matter is not created or destroyed.
What is carbon dioxide?
Carbon dioxide (CO2) is a colorless gas with a sour taste and a little harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
It is produced during the combustion of carbon-containing materials, fermentation, and animal respiration, as well as during the photosynthesis of carbohydrates by plants.
The so-called greenhouse effect is caused by the gas because its presence in the atmosphere prevents part of the radiant energy that Earth receives from being reflected back into space.
In the industrial setting, it is recovered for a wide range of uses from flue gases, by-products of the hydrogen-preparation process for ammonia synthesis, lime kilns, and other sources.
Therefore, the same carbon dioxide will exist in a million years as today.
