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)​

Answers

Answer 1

Answer:

Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis

Answer 2

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.

Answers

Answer:

The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.

Stem cells can be developed into a required tissue because of their ability of cellular DIFFERENTIATION. These cells can develop specialized cells.

Stem cells are cells that can develop into specialized types of cells in order to perform specific functions.

The process of cellular differentiation from stem cells involves differential gene expression patterns, a cellular process that leads to the development of distinct types of cells.

For example, hematopoietic stem cells express specific genes (e.g., the hemoglobin gene) in order to differentiate into mature red blood cells that function to trasnport oxygen to all body cells.

Answer:Plants use carbon dioxide to make food

Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.

Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.

CO₂ + H₂O →  O₂ + glucose (food)

This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.
