Facilitated diffusion is necessary when cell membranes prevents a substance from diffusing on its own.
Facilitated diffusion is a type of passive transport that involves movement of solute materials down the concentration gradient.
Further Explanation;Transport in living organismsPlants and animals use various processes to transport materials from one point to another.There are classified as either passive transport or active transport.Passive transportIt is a type of transport that does not involve the use of energy to aid movement of substances in living organisms.Passive transport involves free movement of substances and through special types of transporters or carriers.Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others.Active transport It is a type of transport in living organisms that involves movement of substances against a concentration gradient and involves use of energy in form of ATP to aid transport of substances.Types of passive transportFacilitated diffusionFacilitated diffusion is a type of passive transport which involves the diffusion of solutes by use of transport proteins in the plasma membrane.Facilitated diffusion uses transport proteins to transport solutes down their concentration gradient. Osmosis Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration.Diffusion Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration.Diffusion involves movement of molecules of substances other than water.Keywords: Passive transport, Diffusion, Osmosis, Passive transport

Which of the following statements about olfactory receptors is false?
They are bulb-like structures at the tip of the frontal lobe where the olfactory nerves begin.
They are cells.
They are located in a mucous membrane at the top of the nose. \
They have small, hair-like extensions.
The false statement about the olfactory receptors is they are bulb-like structures at the tip of the frontal lobe where the olfactory nerves begin.
Further Explanation:
Receptors are the protein molecules present on the cell surface which binds to the ligand and cause response in the immune system. Receptors have the primary role in controlling membrane channels, cell division, and cell growth.
Olfactory receptors are an odour or smell molecules which are mainly found in arthropods, animals and terrestrial vertebrates. These receptors are present in the nasal cavity forming nasal epithelium. It consists of cilia which are covered by the mucus of the nasal cavity. Cilia facilitate the response to olfactory receptors.
Olfactory receptors are not bulb-like structure. It has an olfactory bulb that lies on the ventral aspect of the frontal lobes. Olfactory receptors are the cells located in a mucous membrane at the top of the nose. They have small hair-like extensions which are particularly known as cilia. These cilia contain active sites for the process of olfactory transduction.

I just took the assignment and thats the answer I went with
When animals on other farms respond when they hear rumors about animal farm Rebellion.
What is rebellion?
Each day, Snowball and Napoleon dispatched flocks of pigeons with the instructions to interact with the livestock on nearby farms, share the Rebellion's narrative with them, and teach them the tune to Beasts of England.
This notion was utilized by Presidents Truman, Eisenhower, Kennedy, and Johnson to support their military operations in Vietnam, Greece, and Turkey, nations they wanted to "rescue" from the rise of communism. The owners of the nearby farms in Animal Farm worry about a similar outbreak, which we might refer to as the "Snowball Effect."
Mr. Pilkington and Mr. Frederick propagated false information about Animal Farm in a similar manner to how the West attempted to discredit Russian communism.

All foods contain chemical energy, but the amount of chemical energy is dependent of the type of food. The larger the compound, the more chemical bonds, and the greater amount of available chemical energy. We refer to the stored chemical energy in foods as calories. A calorie is the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius. When we refer to the calories in food, we are really talking about kilocalories or 1000 calories.
Biology students used calorimetry to determine the energy provided by various food samples. They picked food samples of the same mass, 2 grams, and then set the food on fire using kitchen matches. The heat energy of the flaming food was used to heat 100 mL of water. Student results can be seen in the chart above.
What is one condition that may have reduced the accuracy of the temperatures recorded by the student groups?
A) type of foods used in the experiment
B) placement of thermometers in the cans
C) mass of food items used in experiment
D) amount of water measured into the cans
Answer: Option B
Explanation:
The placement of thermometers in the cans be a condition in which the accuracy can be reduced.
Calorie can be defined as the the energy required to raise the temperature of one gram by one degree Celsius.
The weight of the different foods is kept same and the initial temperature is also kept same.
The placement of thermometer should be accurate in order to get the accurate result free of error.

If the sequence in the coding strand of dna for a particular amino acid is 5'agt3', then the anticodon on the corresponding trna would be ________.
The anticodon on the corresponding tRNA would be 5'uga3'.This anticodon binds to the codon on the mRNA during protein synthesis.
Explanation:The coding strand of DNA is the strand that is used as a template to make the mRNA molecule.
In the coding strand, the sequence 5'agt3' corresponds to the sequence 3'tca5' in the template strand.
The anticodon on the tRNA molecule that pairs with the codon 3'tca5' is 5'uga3'.
This anticodon binds to the codon on the mRNA during protein synthesis.

“lord randall” is an example of a ballad whose structure is
Final answer:
The structure of “Lord Randall” is a traditional ballad form, consisting of four-line stanzas or quatrains with an ABCB rhyme scheme and a rhythmic pattern of alternating iambic tetrameter and trimeter.
Explanation:
“Lord Randall” is an excellent example of a traditional Anglo-Scottish ballad. The ballad's structure typically employs four-line stanzas known as quatrains, with an ABCB rhyme scheme where the second and fourth lines rhyme.
The rhythmic composition often follows a pattern of alternating lines of eight and six syllables, which is characteristic of iambic tetrameter alternating with iambic trimeter.
This structure contributes to the musical quality of ballads, which were traditionally sung, often a cappella or with simple instrument accompaniment, and passed down orally from one generation to another to tell a story, usually containing a lesson or moral.
The repetitions and parallelisms in the dialogue of “Lord Randall” help to advance the narrative and are a hallmark feature of balladic storytelling.

Describe the major differences in acute versus passive range of motion (rom) when distinguishing between an articular and nonarticular joint issue.
The major difference between an acute and passive range of motion based on the articular and non-articular problem is that:
In articular problems, active and passive range of motion is restricted. In non-articular problem, only articular range of motion is restricted.
Further Explanation:
The joints are formed by the articulation of the two or more bones and muscles. These joints are the characteristics of the range of motion. The articulation of the bone type determines the type of movement. The articular structure is consisting of synovial fluid, synovium, intra-articular ligaments, articular cartilage, and joint capsule. Bone, muscle, nerve, tendons, ligaments are non-articular structure.
Articular problems are described by swelling, diffuse pain and a very limited range of motion on passive and active movement. Non-articular problems are more painful in the active range of motion, whereas no pain in passive motion.
To examine the active range of motion, a doctor asked a client to move their body. There is no external force or pressure is applied to the body, whereas in a passive range of motion, an external force is applied to move the body. In the case of a particular problem, there is a restriction in the movement of joints.
