Answer:
B.
Explanation:
The only way to make this comparison is by comparing their position to a fixed object outside the vehicle. Comparing to a fixed object inside the vehicle will show no movement, while a moving object inside the vehicle will seem as though the car is still while the object is in motion. Comparing to a moving object outside the vehicle will conflict with the vehicle, if the object is moving at the same speed and direction as the vehicle, it will seem as though neither is moving. The only way to make this comparison correctly is by comparing to an object outside the vehicle that is not moving so that the only variable that can be moving is the vehicle itself.
Answer:
The correct movement would be -
1. Water - into solution A.
2. NaCl - into solution A.
3. glucose - into Solution B.
4. Albumin - neither.
Explanation:
All the substances are separated by the semipermeable membrane and the semipermeable membrane allows the only small molecule to pass through it. So the movement of the given substance would be -
1. Water - into solution A.
Water molecules are small and can easily pass through the semipermeable membrane as it is given that the solution b has low solute concentration and solution A has high solute concentration. It is known that the movement of the solvent always takes place from low solute concentration to high so the movement of water will be into solution A.
2. NaCl - into solution A.
The movement of small ionic molecule NaCl is always from high to low concentration as it is given that solution B has high concentration than solution A so movement will take place into solution A.
3. glucose - into Solution B.
It is also a small molecule and moves from the high glucose region to the low glucose concentration region, in solution A the concentration of glucose is high than solution B so movement would be into solution B.
4. Albumin - neither.
Albumin is a protein which is macromolecule and large in size to pass through the semipermeable membrane so, albumin move neither solution A nor solution B.
Alkanes represent one family of organic compounds that is composed of carbon and hydrogen.
Alkanes are organic compounds that solely have hydrogen and carbon atoms in single bonds and do not have any additional functional groups. Alkanes can be divided into three groups: cycloalkanes, branched alkanes, and linear straight-chain alkanes.
The general formula for alkanes is CnH2n+2. Alkanes are also saturable hydrocarbons. Cyclic hydrocarbons like cycloalkanes have rings-shaped arrangements of their carbon atoms.
Therefore, Alkanes are an example of an organic chemical family made of carbon and hydrogen.

Answer:
A major function of the Endomembrane system is
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.
Explanation:
The endomembrane system (endo = “within”) is a group of membranes and organelles (Figure 4.4. 1) in eukaryotic cells that works together to modify, package, and transport lipids and proteins. The endomembrane system is a series of compartments that work together to package, label, and ship proteins and molecules. In your cells, the endomembrane system is made up of both the endoplasmic reticulum and the Golgi apparatus. These compartments are folds of membranes that form tubes and sacs in your cells.
Hoped this helped! :D
