Dialysis uses the process of simple diffusion.
Dialysis is a kind of treatment that performs some of the functions generally performed by healthy kidneys when the kidneys of the patient are not working properly. Dialysis helps to prevent the accumulation of salt and waste in the body by removing them. When the process of dialysis involves an artificial kidney it is termed hemodialysis while when the blood is cleaned inside the body it is termed peritoneal dialysis.
Simple diffusion is a process in which the solutes pass through a concentration gradient from an area of high concentration to an area of low concentration. Simple diffusion is used in dialysis as waste in the blood is in high concentration so it moves across the semi-permeable membrane to the dialysate.
All other options, such as facilitated diffusion is false as they are not used in the process of dialysis.

If a stimulus is presented repeatedly, followed by no other stimulus, the animal will gradually stop responding. this is known as ____.
The animal will eventually stop responding if the same stimulus is repeatedly provided without being followed by another stimulus. This is known as habituation.
Describe the habituation process:Habituation is a psychological learning process whereby a stimulus's ability to elicit a response decreases over time. According to this theory, a person or an animal might learn to disregard.
What is an example of a habituation?For example, a new sound could first attract your attention or perhaps distract you from what is going on around you. Your response will decrease as you grow accustomed to this sound and give it less attention. Due to repeated exposure, this decreased response is a stimulus that has become habit-forming.

Answer:
In the ferns, the reproductive cycle entails alternation of generations; a spore-producing generation alternates with one that produces eggs and sperm.
Explanation:
A fern is a specific type of vascular plant which reproduces through spores rather than seeds or flowers. Ferns are plants with roots, stalks, and leaves, much like blooming plants. Unlike blooming plants, unfortunately, ferns lack flowers and seeds and rather than reproduce sexually by secreting microscopic spores or occasionally by vegetative means, as is the case with the walking fern.
In previously, many vascular plants that yield spores were loosely classed with ferns and referred to as "fern allies." Surprises concerning the connections between ferns and their companions have been revealed by recent genomic investigations. First, ferns and horsetails seem to have a lot in common. Horsetails are really now included in the fern family. Second, the flora club moss as well as quillworts, which are sometimes referred to as "fern allies," are in no way related to ferns.

When the human body has had adequate rest and no food for 12 hours, it is said to be in the basal state.
What is the basal state?The phrase "basal metabolic rate" (BMR) refers to the overall level of activity of a person's body metabolism as measured by his oxygen consumption in the basal state, which is when the person is completely at rest but not asleep, 14 to 18 hours after eating. The body's oxidative process is more active and the rate of metabolism is higher the more oxygen is used in a certain period of time.
The general metabolic state during treatment has been measured using the BMR. Since thyroid hormones are the main regulators of tissue oxidation and metabolism, BMR measurements were once frequently used to evaluate thyroid function.

Inspiratory reserve volume is a supplementary volume which could be effectively inhaled after the inspiration of a standard tidal volume. It is about 2500- 3100 ml.
Expiratory reserve volume is the additional capacity of air which can be forcibly expelled exhaled after normal expiration. It is around 1200 ml.
