Answer:

Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.

Explanation:

The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!

lilavasa [31]

The given blank can be filled with liver.  

The huge surface area of the small intestine helps in absorption of nutrients. The water-soluble nutrients and small fats enter the bloodstream directly. The inner surface of the small intestine comprises hundreds of folds of compositions known as villi. Within the villi, there are numerous microscopic projections known as microvilli.  

The microvilli substantially enhance the surface area of the small intestine that upsurges the rate of absorption of nutrients. Upon entering the bloodstream the water-soluble nutrients are directed towards the liver prior to being transported to the cells.

Murrr4er [49]

a. When sensory information is detected by a sensory receptor, sensation has occurred. TRUE

For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials, to the central nervous system.

b. All sensory systems have absolute and difference thresholds. FALSE

Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.

c. Sensory receptors are specialized neurons that respond to specific stimuli. TRUE

d. Sensation refers to the way sensory information is organized, interpreted, and consciously experienced. TRUE

Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations.

The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.

<h3>What is osteichthyans?</h3>

A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.

<h3>What is lobe-fins?</h3>

The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.

<h3>What is tetrapods?</h3>

Four-legged vertebrates that make up the superclass Tetrapoda are known as tetrapods, which derives from the Ancient Greek (tetra-) "four" and "foot." It consists of synapsids, dinosaurs, and extinct as well as living amphibians, reptiles, and dinosaur-related birds (including mammals).
