Biology

In mosses, the dominant phase of the life cycle is the haploid gametophyte, which is the green, photosynthetic plant we commonly see. This contrasts with many other plants where the diploid sporophyte is dominant.

Secretin is a hormone, not an enzyme. Chemotrypsin (correctly spelled chymotrypsin) and pepsin are enzymes involved in digestion. Therefore, option B is the correct answer as it is not an enzyme.

Sulphur is classified as a secondary plant nutrient because plants require it in moderate amounts, unlike primary nutrients such as nitrogen and phosphorus which are needed in larger quantities. Therefore, among the options, sulphur is the correct secondary nutrient.

In domestic fowl (birds), females are heterogametic (ZW), meaning they have two different sex chromosomes, while males are homogametic (ZZ). Earthworms and rabbits do not have heterogametic females; rabbits have XY males and XX females, and earthworms are hermaphrodites. Therefore, the correct answer is Domestic fowl.

The abducens nerve (cranial nerve VI) controls the lateral rectus muscle, which abducts the eye. Damage to this nerve results in impaired eye movement, specifically difficulty moving the eye outward.

The protein coat that surrounds the genetic material of a virus is called the capsid. It protects the viral nucleic acid and aids in its delivery into host cells.

The tiger is the largest species in the cat family, known for its size and strength, surpassing lions, leopards, and other big cats.

An albatross is a large sea bird known for its long wingspan and ability to glide over the ocean for long distances. Therefore, option A is correct.

Hepatitis is an inflammation of the liver caused primarily by viral infections, such as hepatitis A, B, C, D, and E viruses. Therefore, the correct cause among the options is a virus.

HMPV stands for Human Metapneumovirus, which is a common respiratory virus. Option A correctly reflects this full form, while the other options are incorrect or fabricated terms.

The aorta is the largest artery in the human body, responsible for carrying oxygenated blood from the heart to the rest of the body. The other arteries listed are smaller and serve more localized regions.

Voluntary muscles are those that can be consciously controlled. The biceps is a skeletal muscle that is voluntary, whereas cardiac muscle, stomach muscle (smooth muscle), and vessels (also smooth muscle) are involuntary.

Serum is the component of blood plasma that remains after the blood has clotted and the clotting proteins have been removed. Therefore, serum is plasma minus its clotting proteins.

The spinal cord is divided into cervical, thoracic, lumbar, sacral, and coccygeal regions. 'Pelvic' is not a recognized region of the spinal cord, making option B the correct answer.

The scientific name Homo sapiens is composed of the genus name 'Homo' and the species name 'sapiens'. Therefore, the Latin name includes the genus and species.

Phosphorus is a key component of nucleic acids, such as DNA and RNA, where it forms part of the phosphate backbone. Amino acids and carbohydrates do not contain phosphorus as a fundamental element.

Vitamin D is primarily produced in the skin when it is exposed to sunlight, specifically ultraviolet B (UVB) rays. This process is essential for calcium absorption and bone health.

The Great White Shark is often considered the largest predatory shark, but the Whale Shark is actually the largest shark species overall. Since the Whale Shark is not listed among the options, the Great White Shark is the largest among the given choices.

Skin, eye, and nose are parts of the face or head, while the leg is a limb of the body. Therefore, the leg does not belong to the group.

Chameleon is a reptile but unlike crocodile, turtle, and alligator, it is not an aquatic or semi-aquatic reptile. Crocodile, turtle, and alligator are primarily associated with water habitats, making chameleon the odd one out.

Fingers do not belong to the group because lungs, eyes, and ears are organs primarily involved in vital bodily functions like breathing, seeing, and hearing, whereas fingers are parts of the body used for touch and manipulation, not sensory organs or internal organs.

An omnivore is an organism that eats both meat and vegetables, which matches Sana's eating habits. Carnivores eat only meat, vegetarians eat only plants, and 'hungry' is unrelated to diet type.

An ophthalmologist is a medical doctor specializing in eye and vision care, making option C the correct answer. Orthodontists specialize in teeth alignment, orthopedists in bones, and obstetricians in childbirth.

A rhinologist is a medical specialist who focuses on diseases and conditions of the nose. The other options refer to specialists in different fields: philologist studies language, endocrinologist deals with hormones, and gerontologist studies aging.

Animals that live in herds are described as 'gregarious,' meaning they tend to associate in groups. While 'sociable' and 'social' relate to interaction, 'gregarious' specifically refers to animals living in groups or herds.
