Multiple choice biology soldiers of defense human lymphatic system lymph and its function lymph and tissue fluid

Cords of billroth are found in

  1. Liver

  2. Kidneys

  3. Spleen

  4. Tonsils
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Cords of Billroth (also known as splenic cords or red pulp cords) are found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages. These cords contain half of the human body's monocytes as a reserve so that after tissue injury these monocytes can move in and aid locally sourced monocytes in wound healing.

Splenic artery arises from 

  1. Anterior mesenteric artery

  2. Coeliac artery

  3. Posterior mesenteric artery

  4. Intestinal artery
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The splenic artery supplying the organ spleen is the branch of the coeliac artery which itself is a branch of the abdominal aorta. The abdominal aorta is a branch of dorsal aorta/systemic aorta.

Dorsal aorta > Abdominal segmental aorta > Coeliac artery > Splenic artery.
So, the correct answer to the question is 'Coeliac artery'.

Which of the following characteristics of tiger helps to reduce the poaching of the tiger? 

  1. Whiskers of tiger help to sense the prey.

  2. The ears are flexible which carries the sound from large distances.

  3. Tigers can smell the urine of another tiger.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The question is poorly phrased, but in the context of wildlife education, these biological traits are often cited as reasons why tigers are elusive and successful predators, which ironically makes them targets for poachers who value these unique biological features.

Annual migration does not occur in case of

  1. Arctic tern

  2. Salamander

  3. Salmon

  4. Siberian Crane
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Migration is used by a number of species, including birds, fish, invertebrates, and mammals, as one strategy for dealing with a seasonally variable environment. In many cases, migration is obligated, but in some species, within a migratory population, only some individuals migrate in a given season (migrants), while the rest remain in the same location (residents), a phenomenon called as partial migration. 

Partial migration can also occur when residents and migrants share a common ground but breed in separate locations. Another form of partial migration occurs when non-migrating individuals actually forgo reproduction this is essentially a special form of low-frequency reproduction. This type of partial migration is well documented in salamanders, newts, sea turtles, and many species of fish.

House sparrow can fly for short distances only because of the absence of 

  1. White muscles

  2. Proper wing span

  3. Pneumatic bones

  4. Red muscles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Red muscles stores ATP in large amount as they ahave abundant of mitochondria in them since house sparrow lacks red muscles it does not have sufficient energy for long flights.

So, the correct option is 'Red muscles'.

Phosphorylation of glucose is increased by

  1. Auxins

  2. Insulin

  3. Ethylene

  4. Traumatic acid
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Phosphorylation of glucose is increased by insulin. Glucokinase is an enzyme which is responsible for phosphorylation of glucose to glucose-6-phosphate with the help of insulin, secreated by beta cells. Beta cells release insulin in response to rising levels of glucose. Insulin enables many types of cells to import and use glucose, and signals the liver to synthesize glycogen. While alpha cells produes more of glucagon. Glucagon serves as a signal to the liver to break down glycogen and release glucose into the blood. Glucokinase in beta cells serves as a glucose sensor, amplifying insulin secretion as blood glucose rises.

Which of the following is not an example of phytohormone?

  1. cytokinins

  2. ethylene

  3. auxins

  4. insulin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Insulin is not a phytohormones, while cytokinins, ethylene and auxins are examples of phytohormones. Phytohormones are produced within a plant and are essential for the plant growth. Insulin is a peptide hormone, produced within human beings, by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats.

Splenic artery arises from?

  1. Anterior mesenteric artery

  2. Coeliac artery

  3. Posterior mesenteric artery

  4. Intestinal artery
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The splenic artery  is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It supplies oxygenated blood to the arteries.
So, the correct option is 'Coeliac artery'.

Squamous epithelium forms inner lining of which of the following?
I. Blood vessels
II. Lung alveoli
III. Salivary duct

  1. I and II only

  2. II and III only

  3. I, II and III only

  4. II and IV only
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Squamous epithelium is a thin, flat layer of cells ideal for diffusion. It forms the inner lining of blood vessels (endothelium) and the alveoli of the lungs, where gas exchange occurs.

Larynx open into pharynx by

  1. Gullet

  2. Glottis

  3. Epiglottis

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The lowest part of pharynx is the laryngopharynx. It has two apertures, the anterior slit is 'glottis', through which it opens into the larynx and the posterior slit is 'gullet', which leads to the oesophagus.
  • Thus, larynx opens into the pharynx by glottis. The glottis bear a leaf-like a cartilaginous flap, called the 'epiglottis'. Epiglottis cover the glottis during swallowing, to prevent the entry of food into it.
    Hence, the correct answer is B.

Nasal and oral cavities in human is separated by

  1. Diaphragm

  2. Palate

  3. Trachea

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The palate is the roof the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate. The palate is divided into two parts, the anterior bony hard palate, and the posterior fleshy soft palate (or velum). The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continuously, and most of the time, involuntarily. The trachea, colloquially called windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air. Thus, option B is correct.

Nasal chambers and buccal cavity are separated by

  1. By uvula

  2. By palate

  3. By palatine

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The oral and nasal cavities lie near the body midline, inferior and medial to the orbital cavities, anterior to the pharynx and medial to the infratemporal fossa.
  • They are separated from one another by the palate. 
  • Each cavity has an entrance and an exit. Hence, Nasal chambers and buccal cavity are separated by the palate.
So, the correct answer is 'By palate'.
