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.

You are learning about mimicry in entomology. Which microscope would be best to look at the wings of two different butterflies to determine which is a Monarch Butterfly and which is a Viceroy Butterfly?

Answers

SEM scanning electron microscopy

The greatest tool to use to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly is a scanning electron microscope, hence option C is correct.

What is a scanning electron microscope?

A focused stream of electrons is used by an electron microscope known as a scanning electron microscope (SEM) to scan a sample's surface and produce images of the material.

Various signals that reveal information about the sample's surface topography and composition appear as the electrons make contact with the sample's atoms.

The electron beam is scanned using a raster scan pattern, and an image is produced by fusing the position of the beam with the intensity of the signal that is detected.

Therefore, to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly with a scanning electron microscope,  hence option C is correct.

Photosynthesis

Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.

Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.

During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

Answers

Answer:

Enzyme inhibitor

Explanation:

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.

define the following terms:dispersion and refraction ​

Answers

Explanation:

Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Refraction is responsible for dispersion in rainbows and many other situations. The angle of refraction depends on the index of refraction, as we saw in The Law of Refraction.
