Cuboidal epithelium is found in thyroid follicles.

Thyroid follicles are reasonable for the production and secretion of thyroid hormone. They are made up of Cuboidal epithelium. Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid.

Titchener was most closely associated with the structuralist school of psychology. Structuralism proposes that the structure of conscious experience could be understood by analyzing the basic elements of thoughts and sensations. Structuralism is considered the first school of thought in psychology, and was established in Germany by Wilhelm Wundt, and mainly associated with Titchener.

Gregor Mendel used pisum sativum plant for genetic experiments.

The apparent weight of a person:

(A) When the lift moves upward with acceleration a. Then the net upward force on the person is-

R – mg = ma

∴ Apparent weight, R = mg + ma = m(g + a)

So when a lift accelerates upwards, the apparent weight of the person inside it increases.

(B) When the lift moves downwards with acceleration a. Then the net downward force on the person is-

Mg - R = ma

∴ Apparent weight, R = mg - ma = m(g - a)

So when a lift accelerates downwards, the apparent weight of the person inside it decreases.

(C) When the lift is at rest or moving with uniform velocity v downward/upward. The acceleration a = 0, then the net force on the person is-

R – mg = m × 0 = 0

R = mg

∴ Apparent weight = Actual weight

(D) When the lift falls freely. If the supporting cable of the lift breaks, the lift falls freely under gravity. Then a = g. The net downward force on the person is:

R = m(g - g) = 0.

Thus the apparent weight of the man becomes zero. This is because both the man and the lift are moving downwards with the same acceleration ‘g’ and so there are no forces of action and reaction between the person and the lift. Therefore a person develops a feeling of weightlessness when he falls freely under gravity.

Loss of Cerebellum leads to decreased muscle coordination.

• The cerebellum does not controls movements, speech, sight, smell, taste, hearing, intelligence, etc.
• Activities like walking in a straight line, riding a bicycle, picking up a pencil are possible due to a part of the hindbrain called the cerebellum.
• It is responsible for the precision of voluntary actions and maintaining the posture and balance of the body.
• It is a part of the hindbrain.

The process of adjustment is dynamic. The adjustment, in psychology, is the behavioral process by which humans and other animals maintain an equilibrium among their various needs or between their needs and the obstacles of their environments. A sequence of adjustment begins when a need is felt and ends when it is satisfied. Hungry people, for example, are stimulated by their physiological state to seek food. When they eat, they reduce the stimulating condition that impelled them to activity, and they are thereby adjusted to this particular need.

Any relatively permanent change in behavious brought about by experience or practice is called learning.

• According to the psychologist, Learning is a relatively permanent alteration in behaviour as an outcome of the experience.
• It is typically based on an individual, how they face and respond to any situation in the surroundings and learn from the process.
• Psychologist believes that all behaviours are the outcome of learning in society.

Throughout time, an individual learns by involving in various activities which help them to acquire knowledge and skills from their experience that alter their behaviour or change their way of reaction.

Enhancer sequences are regulatory DNA sequences. This sequences are bound by specific proteins called transcription factors. The binding of these proteins will enhance the transcription of an associated gene. They are not the part of the operon structure.

Prior infection with group (A) streptococcus within the past 10–14 days most commonly causes acute glomerulonephritis. Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group (A) Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine, and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.

Sperm is nourished by a sugary fluid from the prostate gland.

Along the way sperm is nourished by a sugary fluid from the Prostate gland which is the most common site for cancer in men, and fluid from the Cowper's gland which are two small glands located near the bladder.

Vitamin C is a water-soluble vitamin.

Vitamin C is active in the body either as L-ascorbic acid or as dehydroascorbic acid. Its best-known function is as a cofactor for the enzyme required to hydroxylate prolyl and lysyl residues for the synthesis of connective tissue proteins.

The water-soluble vitamins include ascorbic acid (vitamin C), thiamin, riboflavin, niacin, vitamin B₆ (pyridoxine, pyridoxal, and pyridoxamine), folacin, vitamin B₁₂, biotin, and pantothenic acid.

Tay-Sachs disease in humans is an example of a recessive lethal allele.

The nurse ensures to take another bottle of solution.

Fat emulsions are used as dietary supplements for patients who are unable to get enough fat in their diet, usually because of certain illnesses or recent surgery. The nurse should examine the bottle of fat emulsion for separation of emulsion into layers or fat globules or the accumulation of froth. The nurse should not hang a fat emulsion if any of these are observed and should return the solution to the pharmacy.

Calcaneus bone is not found in the hand.

• Carpal bones, metacarpals and phalanges bones are found in the hand.
• The calcaneus is located in the hindfoot with the talus and is the largest bone of the foot.
• It is commonly referred to as the heel.

When a man is stressed in the office, he reaches home and beats his wife and children so that he can release his stress, he is using displacement defense mechanism. Displacement is a psychological defense mechanism in which a person redirects a negative emotion from its original source towards a less threatening recipient. A classic example of defense is displaced aggression.

A segment of DNA that codes for a protein or RNA molecule describes a gene.

Your description of who you are as a person is your self concept.

Self concept is used to refer to how someone thinks about, evaluates, perceives, or describes themselves. To be aware of oneself is to have a concept of oneself. The self-concept is the accumulation of knowledge about the self, such as beliefs regarding personality traits, physical characteristics, abilities, values, goals, and roles. In an individual, the self-concept becomes more abstract, complex, and hierarchically organized into cognitive mental representations or self-schemas, which direct the processing of self-relevant information.

The bulbs are connected in parallell. So, the same voltage is applied across them. In that case, the higher the power rating of the bulb, the higher will be its brightness since more current flows through it. Hence, bulb B (60W) will be brighter than bulb A (40W).

Polio is a viral disease.

• Bahutrisha, also often referred to as polio or 'poliomyelitis', is a viral infectious disease that is usually transmitted from person to person through infected feces or food.
• India launched the Pulse Polio Vaccination (PPI) program in 1995 as a result of the World Health Organization's global polio eradication effort.

In a uniform circular motion, the angular velocity is given as,

So, the time period of the motion is,

By decreasing the heart rate and contractility, beta-adrenergic blockers improve myocardial filling and cardiac output, which are primary goals in the treatment of cardiomyopathy. Cardiomyopathy is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy.

A persistent, craziness to eat non-nutritive non edible items is known as pica.

• Pica is a type of eating disorder.
• People with pica eat anything, especially those things that do not contain any kind of nutrients.
• In this disorder, people start eating ice, metal, soil, dry paint, or other dangerous objects.
• Due to which there is a risk of spreading poison or harm to the person's body.

The National Vector Borne Disease Control Programme (NVBDCP) in India primarily focuses on vector-borne diseases transmitted by vectors such as mosquitoes. The diseases typically covered under this program include:

1. Malaria
2. Dengue fever

H1N1 (Swine Flu) is not a vector-borne disease; it is a respiratory illness caused by a virus and is managed under a different program.

Therefore, the correct answer is:

3. H1N1 (Swine Flu)

A mastoidectomy can treat complications of Chronic otitis media. A mastoidectomy is a surgical procedure that removes diseased mastoid air cells. The mastoid is the part of your skull located behind your ear. It's filled with air cells made of bone and looks like a honeycomb. The diseased cells are often the result of an ear infection that has spread into your skull.

Antiembolic stockings can help to reduce thromboembolism. Antiembolic stockings, also known as TED hose, are designed specifically for non-mobile patients or those confined to a bed. They are low cost temporary solutions commonly used for patients in nursing homes and post-surgery to prevent deep vein thrombosis (DVT).
