Answer 1 :-
(i) A seed dispersed by animals.
- Examples are Xanthium and Urena etc.
- They have hook like structure which attach with animals body and They get are carried to distant places.
(ii) A seed dispersed by birds.
- Blackberry, cherry, tomato and apple etc seeds are dispersed by birds.
- They are attracted towards by their color and taste so, they eat whole fruit with seed. During excretion the seeds come out and begain to start growing as new plant.
(iii) Organelles with double layered covering.
- Mitochondria and chloroplasts both have double double layered covering or membranes.
- These membrane are mostly formed of Lipids and Protien.
(iv) Protein digesting enzymes.
- Pepsin and Trypsin helps in breaking down of Protein.
- But they produced at different places such as Pepsin is produced in stomach and Trypsin formed in produced in Pancreas.
Answer 2 :-
Mul Nutrition :-
- Malnutrition is a condition in which a person does not get enough nutrients for proper function of its body.
- It generally happens due to not getting enough food.
- It affects the learning capability of children, making them unproductive in their later life. also mortality rate.
- For reducing malnutrition a person have to get and eat Fresh fruits , Vegetables, Meat, Milk.
Under-nutrition :-
- Unhealthy state of the body due to the intake of a lesser quantity of food is called undernutrition.
- Also, It happens due to not getting required enough food.
- It hamper the body growth and it leads to of physical, mental or metabolic disabilities in people of all age groups.
- Daily taking of enough and healthy food can also reduce Under - Nutrition.
