Multiple choice biology animal world oviparous and viviparous number and shape of cells unicellular and multicellular organisms diversity and classification in animals adaptations in animals

Birds are considered oviparous

  1. They are able to fly

  2. The forelimbs are modified into wings

  3. They lay eggs

  4. None of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ovipary is the phenomenon in which an adult organisms reproduces and lays eggs which later hatch and give rise to young ones.

Since birds lay eggs they are known as oviparous.
Flight or wing modifications are not related to this phenomenon.
So the correct answer is 'They lay eggs'.

Birds and snakes are oviparous animals.

  1. True

  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Oviparous are the animals which lay eggs. Snakes belong to class Reptilia and birds belongs to class Aves. They lay eggs. The eggs hatch by the warmth of the body. The yolk of the egg provides nutrition to the developing embryo.
So, the correct answer is option A.
Multiple choice biology reproduction in animals story of dolly, the clone sheep story of dolly, the clone process of cloning

Cloning is the production of an exact copy of a cell, any other living part of a complete organism. A sheep named Dolly was the first mammal to be cloned by Ian Wilmut and his colleagues at the Roslin Institute in Edinburgh. Find out the incorrect statements about the cloning of Dolly.

(i) Dolly was born on 5th July 1996.
(ii) Dolly was given birth by the Finn Dorset sheep.
(iii) Dolly was found to be absolutely identical to the Scottish blackface ewe.
(iv) The nucleus of the mammary gland cell from the Finn Dorsett sheep was inserted into the egg of the Scottish blackface ewe whose nucleus had been removed.

  1. (i) only

  2. (i) and (iii) only

  3. (i), (ii) and (iii) only

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dolly was born on July 5, 1996, at Roslin Institute, the first mammal known to be cloned. A cell taken from the mammary gland of a 6-year-old Finn Dorset ewe was cloned through a technique known as nuclear transfer. The reproductive egg cells were removed from another female sheep, a ewe of a Scottish Blackface. Scottish Blackface egg cells were then fertilized with the genetic material from the Finn Dorset mammary cells and they fertilized cell was transferred to the uterus of the surrogate mother. On July 5, 1996, Dolly was born from one of the surrogate Blackface ewes which were identical to the Finn Dorset sheep.

Multiple choice bio-chemistry nervous system of man introduction to brain body fluid central nervous system

The space between the layers of the brain is filled with fluid is called ...........

  1. Cerebrospinal fluid

  2. Pleural fluid

  3. Synovial fluid

  4. Aqueous humour

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A. Cerebrospinal fluid is a clear liquid produced within spaces in the brain called ventricles. Like saliva, it is filtrate of blood. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and spinal cord.
B. Pleural fluid is a thin translucent fluid that fills the cavity between the parietal(outer) and visceral(inner) pleural layers surrounding the lungs.
C. Synovial fluid also called synovia is a vicious, non- Newtonian fluid found in the cavities of synovial joints.
D. Aqueous is a thin, watery fluid located in the anterior and posterior chambers of the eye.
So, the correct answer is "Cerebrospinal fluid".

Stratum germinativum is an example of which kind of epithelium?

  1. Columnar

  2. Squamous

  3. Cuboidal

  4. Ciliated

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The stratum germinativum is the deepest layer of the five layers of the epidermis. The stratum basale is a single layer of columnar or cuboidal cells.
So, the correct option is 'cuboidal'.

The epithelium which forms the inner wall of blood vessels is_____________

  1. Cuboidal epithelium

  2. Ciliated epithelium

  3. Squamous epithelium

  4. Compound epithelium

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The simple squamous epithelium that lines the blood vessels is called the endothelium. The endothelium is the thin layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary. These cells reduce turbulence of the flow of blood allowing the fluid to be pumped farther. 
Endothelial tissue is a specialized type of epithelium tissue (one of the four types of biological tissue in animals). More specifically, it is a simple squamous epithelium.

The covering tissue of external and internal surfaces of animal body is

  1. Connective

  2. Epithelial

  3. Muscular

  4. Areolar

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The external surfaces and internal linings of the animal body are made up of various kinds of epithelial tissues. Epithelial tissues have various functions all across our bodies like secretion, absorption, protection, sensing and, to some extent, thermoregulation. So, the correct answer is 'Epithelial'.

Multiple choice biology what do animals eat? introduction to animal nutrition food for life types of nutrition

Birds take nectar by ________

  1. Chewing

  2. Swallowing

  3. Sucking

  4. Biting

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Birds take nectar by sucking it from the flowers. Birds that suck have slender, curved bills whose tongue are long and slender. When bird pokes its bills into the flower and extends its tongue, the straw-like tip will automatically take up some of the nectar through capillary action.
So, the correct answer is 'Sucking'.
Multiple choice zoology excretory system of human other excretory organ role of other organs in excretion accessory excretory organs

Which of the following passage way is part of cloaca of vertebrates?

  1. Rectum

  2. The reproductive tract

  3. The urinary tract

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cloaca is the posterior opening that serves as the only opening for the intestinal, reproductive and urinary tracts of all amphibians, birds, reptiles, and monotremes. They possess this orifice, from which they excrete both urine and feces, unlike most placental mammals, which possess two or three separate orifices for evacuation.

Multiple choice biology habitat and adaptation terrestrial adaptations in plants desert ecosystem adaptation in terrestrial plants

Which of the following is an important adaptation of animals too the cold climate?

  1. Thin layer of body fat

  2. Aestivation

  3. Increased tendency to shivering

  4. Reduced surface area to volume ratio

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Temperature affects the the absolute size of an animal and the relative proportions of various body parts, Birds and mammals attain grater body size in cold regions than in warm areas. But poikilotherms are smaller in cold region. This is Bargeman's rue. This is true because small animals have larger surface area relative to their volume, so if they are in cold, they lose their body heat very fast. In cold climate, reduced surface area to volume ratio is ideal. So, the correct answer is 'Reduced surface area to volume ratio'.

Multiple choice biology habitat and adaptation terrestrial adaptations in plants desert ecosystem adaptation in terrestrial plants

Which of the following is not an important adaptation of animals to cold climate?

  1. Thin layer of body fat

  2. Aestivation

  3. Increased tendency to shiver

  4. Reduced surface area to volume ratio

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The animals living in cold climate have various physiological adaptations like:

1) A thick layer of body fat called as Blubber to avoid loss of heat from body tissue.

2) Hibernation is a property of suspended metabolism in these organisms to surpass cold conditions.similar mechanism called aestivation exists in desert animals to survive in arid and hot conditions.

3) Increased tendency to shiver causes an increase in body temperature because of exercise thus help to withstand low temperatures.

4) The reduced surface area to volume ratio to prevent heat loss from the body surface. So, the correct answer is 'Aestivation'.
