Cell membranes are made up of a bilayer of phospholipids that are very selective about what substances can pass through.The table below shows the different types of molecules that can enter a cell. It compares the concentration on the outside to the inside of the cell, its relative size, and whether it is polar, nonpolar, or an ion. Determine how each molecule can pass into the cell. Is it by passive transport, active transport, or endocytosis? (3 points)
Answer:
Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis
Explanation:
js trynna get points lol
The molecules can pass into the cell by passive transport, active transport, or endocytosis.
Molecule | Concentration Outside | Concentration Inside | Size | Polarity | Transport | Mechanism
Glucose High Low Small Polar Diffusion
Oxygen High Low Small Nonpolar Diffusion
Sodium High Low Small Ion Active transport
Chloride Low High Small Ion Active transport
Amino acids Low High Medium Polar Carrier-mediated transport
Large protein Low High Large Polar Endocytosis
Glucose and oxygen can pass into the cell by diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Glucose and oxygen are both small molecules, and they are both polar. This means that they can dissolve in the phospholipid bilayer of the cell membrane.
Sodium and chloride can pass into the cell by active transport. Active transport is the movement of molecules from an area of low concentration to an area of high concentration. Sodium and chloride are both ions, which means that they are charged particles. This means that they cannot dissolve in the phospholipid bilayer of the cell membrane. Instead, they need to be transported across the membrane by special proteins called ion pumps.
Amino acids can pass into the cell by carrier-mediated transport. Carrier-mediated transport is a type of passive transport that uses carrier proteins to transport molecules across the cell membrane. Amino acids are polar molecules, but they are larger than glucose and oxygen. This means that they cannot simply diffuse across the cell membrane. Instead, they need to be transported across the membrane by carrier proteins.
Large protein can pass into the cell by endocytosis. Endocytosis is a process by which the cell engulfs large molecules or particles. The cell membrane forms a pocket around the molecule or particle, and then the pocket pinches off to form an endocytic vesicle. The endocytic vesicle then fuses with a lysosome, where the molecule or particle is broken down.

why are there earthquakes
Answer:
Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

Gel electrophoresis allows molecules to migrate along the gel at different rates by using:
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.
