A
Weapons or for killing prey

B
Grinding and chewing food

C
Cutting and slicing food

D
All of these

Solution

Incisors are the front four teeth which are used for cutting/biting and slicing the food, canines are the pointed teeth which helps in tearing the food whereas molars are the teeth which are used for Grinding and chewing of food particles.
So, the correct option is 'Cutting and slicing food'
Question 2
1 / -0

Select the incorrect pair-

A
Secondary lysosome - Digestive vacuole

B
Residual bodies - Autolysis

C
Contractile vacuole - Helps in excretion in Amoeba

D
Golgi apparatus - Glycosidation of lipids
Solution
Solution:
Correct answer is option B.
Explanation for correct option:
Residual bodies are cytoplasmic vacuole containing the leftover products of digestion after fusion with the contents of a lysosome.
Residual bodies are either secreted by the cell via exocytosis (this generally only occurs in macrophages), or they become lipofuscin granules that remain in the cytosol indefinitely.
They are not involved in autolysis like that of lysosomes.

Explanation for incorrect option:
Rest all given options matches correctly with their function.
Question 3
1 / -0

The teeth which help us in chewing and grinding the food we eat are?

A
Canines

B
Incisors

C
Premolars

D
Molars
Solution
There are four types of teeth-
Incisors - There incisors are eight teeth in the front center of the mouth. Incisors are the teeth that use to bite into food.
Canines - The canines are the next teeth that develop in the mouth. These are the sharpest teeth, used for tearing apart food.
Premolars - Premolars are used for tearing and crushing food. Unlike the incisors and canines, premolars have a flat biting surface. There are eight premolars in total.
Molars - The molars are the largest teeth. Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.
So, the correct option is D.
Question 4
1 / -0

Which type of teeth is most prominent in carnivorous animals?

A
Incisors

B
Canine

C
Premolar

D
Molar

Solution

Canines are teeth used for tearing because of their pointed ends, they are prominent and well developed in carnivores for tearing flesh.
So, the correct answer is 'Canine.'
Question 5
1 / -0

Cud is the name given to the food of ruminants which is

A
Swallowed and undigested.

B
Swallowed and partially digested.

C
Properly chewed and partially digested.

D
Properly chewed and completely digested.

Solution

Cud is the partially digested food in the rumen of ruminants like cow.
So, the correct answer is option (b).
Question 6
1 / -0

The diagram below represents the digestive system from ____________ group of animals .

A
Ruminant herbivore

B
Non-ruminant herbivore

C
Bird

D
Carnivore animal
Question 7
1 / -0

Choose the correct order of terms that describes the process of nutrition in ruminants.

A
Swallowing $$\to$$ Partial digestion $$\to$$ Chewing of cud $$\to$$ Complete digestion

B
Chewing of cud $$\to$$ Swallowing $$\to$$ Partial digestion $$\to$$ Complete digestion

C
Chewing of cud $$\to$$ Swallowing $$\to$$ Mixing with digestive juices $$\to$$ Digestion

D
Swallowing $$\to$$ Chewing and mixing $$\to$$ Partial digestion $$\to$$ Complete digestion

Solution

The process of nutrition in ruminants is Swallowing of food $$\rightarrow$$ Partial digestion of the food in the ruminant's stomach (rumen) to form cud $$\rightarrow$$ Cud returns to the mouth in small lumps $$\rightarrow$$ Chewing of cud $$\rightarrow$$ Complete digestion takes place.
So, the correct answer is option A.
Question 8
1 / -0

How many molar teeth are present in each jaw?

A
One

B
Two

C
Four

D
Six

Solution

The number of molar teeth present in jaw is
2$$\times$$3 or 6
So, the correct answer is 'Six'
Question 9
