The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell.
Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.
When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.
The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.
The ribosome represents the actual site of protein synthesis.The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

1.) Which statement correctly describes the relationship between the volume of a gas and it’s temperature, in Kelvin, assuming pressure is held constant?
A.) The relationship is directly proportional; as temperature increases, volume decreases in the same way.
B.) The relationship is inversely proportional,
As temperature increases, volume decreases in the same way.
C.) The relationship is directly proportional, as temperature increases, volume increases in the same way.
D.) The relationship is inversely proportional, as temperature increases, volume increases in the same way.
2.) which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant
A.) an increase in pressure causes particles to move farther apart, decreasing the volume
B.) an increase in pressure causes particles to move farther apart, increasing the volume
C.) an increase in pressure causes particles move closer together, decreasing the volume.
D.) an increase in pressure causes particles to move closer together, increasing the volume.
3.) The ideal gas law is represented by PV = nRT. as volume is held constant and the temperature increases, how would the pressure be expected to change
A.) it will remain constant.
B.) it would decrease.
C.) it would increase
D.) it would become zero
4.) when the pressure of gas decreases, which quantity will increase, assuming all other variables are held constant?
A.) R
B.) n
C.) T
D.) V
5.) two balloons hold two different gases. The gases are held at the same pressure, volume, and temperature. Which quality can difference between the two gases?
A.) The molar volume of each gas
B.) The mass of each gas.
C.) The gas constant of each gas.
D.) The number of moles of each gas
Answer:
1. The relationship is directly proportional; as temperature increases, volume increases in the same way.
2. An increase in pressure causes particles to move closer together, decreasing the volume.
3. It would increase.
4. V
5. The mass of each gas.
Just took it
Remember that the equation for the ideal gas is:
P*V = n*R*T
Where:
P = pressure
V = volume
n = number of moles
R = constant of the ideal gases.
T = temperature.
1) If the pressure is held constant (we also assume n is constant, because usually, the number of moles does not change).
Then we can write
V = (n*R/P)*T
and (n*R/P) is a constant.
Then the above relation is a proportional relation.
So the correct option is C: The relationship is directly proportional, as temperature increases, volume increases in the same way.
2) If the pressure increases and the temperature is held constant, then the equation:
V = (n*R/P)*T
can be used.
Now the temperature is constant, so we can write this as
V = (n*R*T)/P
Where now (n*R*T) is a constant.
So now we have an inversely proportional relation, when P increases, the volume should decreases. And a decrease in volume happens because the molecules move closer together, so the correct option is C:
"an increase in pressure causes particles move closer together, decreasing the volume."
3) Now the volume is constant, then we can write:
P = (n*R/V)*T
Exact same thing as in the first case, this is a proportional relation, so if the temperature increases, also does the pressure.
The correct option is C again.
4) If the pressure decreases then temperature also decreases, as we saw above.
And as the temperature decreases, the volume increases, as we saw in point (2), then the correct option is D, i the pressure decreases, the volume increases.
5) We have two different gases with the same values of T, V, and P.
By the equation:
P*V = n*R*T
And knowing that R is a constant, we can see that n should also be the same value for both gases.
Then the molar volume of each gas, V/n, is also the same.
Finally, the only thing that can be different in the gases is the thing that does not appear in the equation, and that is density/mass. So we can conclude that the gasses have different masses (thus different density, as they have the same volume)
Then the correct option is B; the mass of each gas.

Recalling Interactions among Organisms
Identify the interaction described.
✔ commensalism
One species benefits and the other species is neither harmed nor helped.
✔ mutualism
Both species benefit.
✔ parasitism
One species benefits and the other species is harmed.
Humans release carbon dioxide that plants need; plants provide oxygen that humans need.
Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.
Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals.
The humans releasing carbon dioxide, tapeworms entering a human’s intestines or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.
What is mutualism?In mutualism, humans release carbon dioxide that plants need; plants provide oxygen that humans need as both species benefit from the interaction. In parasitism, tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human one species benefits at the expense of the other.
In commensalism, remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals as one species benefits from the interaction, while the other is neither helped nor harmed.
Therefore, humans releasing carbon dioxide, tapeworms entering a human’s intestines through contaminated water and stealing nutrients from the human or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.

Can you observe cells with the naked eye? Explain.
Answer:
No
Explanation:
According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.
As cell is a tiny microscopic structure, it can be visible under microscope only.
what are the types of cell ?Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.
The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
