Animal Tissue and Anatomy Questions

Multiple choice biology animal tissue types of neuron nervous tissue neural tissues

Which of the following is not a connecting tissue?

  1. Blood

  2. Bone

  3. Lymph

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

Bone, Blood and Lymph are all types of specialized connective tissue. But, nerve cells belong to a different set of tissues named nervous tissue. Nervous Tissues are the primary tissue of the nervous system that allows communication between various organs and tissues. It is composed of glial cells and neurons.

So, the correct answer is 'Nerve'.

Multiple choice biology butterfly and honey bee life cycle of a butterfly metamorphosis in frogs the life of a butterfly types of reproduction in animals oviparous and viviparous

Which of the following hormones controls metamorphosis in a frog?

  1. Adrenaline

  2. Insulin

  3. Oxytocin

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

Metamorphosis includes the developmental changes during the life span of an organism. The thyroxine hormone released from the thyroid gland brings the developmental changes during the metamorphosis. Thyroxine regulates the metabolism of an organism.

So, the correct answer is option D.

Structure which remains unchanged, during metamorphosis of frog's tadpole is

  1. Lung

  2. Heart

  3. Brain

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

The nervous system undergoes least changes during metamorphosis of frog's tadpole. Frog's nervous system once differentiated remains as such throughout life. However, the brain acquires its normal shape and size. 

Therefore, the correct answer is option C.

Tadpoles of frog can be made to grow as giant sized tadpoles, if they are

  1. Administered anti-thyroid substance like thiourea.

  2. Administered large amounts of thyroxine.

  3. Reared on a diet rich in egg yolk.

  4. Reared on a diet rich in both egg yolk and glucose.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Xenopus laevis tadpoles that arrest development and remain as larvae for several years sometimes occur spontaneously in laboratory populations. These tadpoles cease development at an early hindlimb stage, but continue to grow and develop into grossly deformed giants. Giant tadpoles lack thyroid glands, and differ in morphology and behaviour from normal larvae. Tadpoles of frog can be made to grow as giant sized tadpoles, if they are administered large amounts of thryoxine.

What is the main food of young tadpoles?

  1. Other tadpoles

  2. Algae and other plant material

  3. mall aquatic invertebrates

  4. Leftovers thrown by man
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A tadpole (also called a pollywog) is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial. When first hatched from the egg they have a more or less globular body, a laterally compressed tail and internal or external gills. As they grow they undergo metamorphosis, during which process they grow limbs, develop lungs and reabsorb the tail. Most tadpoles are herbivorous. 

So the correct option is 'algae and other plant material'.

Multiple choice botany modes of reproduction fertilization in organisms sexual reproduction in organisms reproduction in organisms

The phenomenon of endogamy is reported in

  1. Fasciola

  2. Earthworm

  3. Marchantia

  4. Rabbit
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fasciola is a genus of trematodes. It is commonly known as liver fluke. It shows the phenomena of endogamy where the two fusing gametes are derived from the same parent which means the gametes are uniparental. These are hermaphrodite and has both male and female reproductive organs. The male and female reproductive organs open up into the same chamber within the body, which is called the genital atrium where the two gametes fuses.

So, the correct answer is option A.

Multiple choice zoology locomotion and reproduction flagella other cell components single membrane bound organelles

In eukaryotic flagella, membrane bound central part is termed as?

  1. Shaft

  2. Central sheath

  3. Axonema

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

Inside cilia and flagella is a microtubule-based cytoskeleton called the axoneme. The axoneme of primary cilia typically has a ring of nine outer microtubule doublets (called a 9+0 axoneme), and the axoneme of a motile cilium has two central microtubules in addition to the nine outer doublets (called a 9+2 axoneme). The axonemal cytoskeleton acts as a scaffolding for various protein complexes and provides binding sites for molecular motor proteins such as kinesin II, that help carry proteins up and down the microtubules.


So the correct option is 'Axoneme'.

Multiple choice zoology locomotion and reproduction flagella other cell components single membrane bound organelles

Movement of cilia and flagella is due to presence of

  1. Central sheath

  2. Dynein

  3. Radial spokes

  4. Singlet tubules.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dynein is a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechnical work, and hence are involved in movement of cilia and flagella.

So, the correct option is 'Dyenin'.

Multiple choice zoology earthworm structure of earthworm earthworm - morphology, integumentary system , respiration and nervous system adaptations

The clitellum of Pheretima is present in segments 

  1. 12,13 and 14

  2. 13, 14 and 15

  3. 14, 15 and 16

  4. 15, 16 and 17
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The clitellum is a thickened glandular and non-segmented section of the body wall located in 14, 15 and 16 segment of the earthworm that secretes a viscid sac in which the eggs are deposited.
  • The clitellum is part of the reproductive system of earthworm. It also secretes a viscous fluid to form a cocoon for it's eggs. In earthworms the clitellum can only be seen when the worm is sexually mature.
So, the correct option is '14, 15 and 16'.
Multiple choice zoology earthworm structure of earthworm earthworm - morphology, integumentary system , respiration and nervous system adaptations

Gustatoreceptors of Pheretima are present

  1. In the buccal cavity

  2. In the prostomium

  3. In the peristomium

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

Gustoreceptors are found in the epithelial of the buccal cavity,these cells have sensory hair like processes and their nuclei lie below the middle part of the cells. These receptors severs to smell (olfactory receptors) for taste (gustoreceptors). Earthworms can smell different types of decaying food. Hence gustoreceptors are present in the buccal cavity. 

So the correct answer is 'In the buccal cavity'.

What are the chemicals secreted by damaged mast cell of connective tissue?

  1. Pepsin and renin

  2. Lysozyme and somatostatin

  3. Melanin and coherin

  4. Histamine and heparin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A mast cell is a resident cell of connective tissue that contains many granules rich in histamine and heparin.
  • Mast cells are allergy cells responsible for immediate allergic reactions. They cause allergic symptoms by releasing Histamine and heparin.
  • Hence the chemicals secreted by damaged mast cell of connective tissue are Histamine and heparin.
  • So, the correct answer is 'Histamine and heparin'.
