Question

members of a species have common characteristics and capable to reproduce fertile offspring (true and false)​

Answer 1

Answer:

Ans: The following first aid should be provided to victims of disasters:

 Airway: If the victim has difficulty in breathing, the head should be held in a

backward sloping position or the chin should be raised so that the respiratory

passage remains open.

 Breathing: If breathing has stopped, the victim should be given artificial

ventilation by mouth to mouth resuscitation.

 Circulation: If the victim is unconscious, then after giving mouth to mouth

respiration twice, the heart should by pressed down hard by pressing the chest

with both the palms. These two actions should be repeated alternately about

15 times. This is called cardio-pulmonary resuscitation (CPR). It helps to

bring the circulation back to normal.

For specific injuries like bleeding, fracture and burns, the following first-aid

is to be given:

 Bleeding: If the victim is injured and bleeding through the wound, then the

wound should be covered with an antiseptic pad and pressure applied on it for

5 minutes with either thumb or palm.

 Fracture and impact on vertebrae: If any bone is fractured, it is essential

that the fractured part be immobilized. It can be done with the help of any

available wooden rods/batons/rulers. If there is an impact on the back or

vertebral column, the patient should be kept immobile on a firm stretcher.

 Burns: If victims have burn injuries, it is beneficial to hold the injured part

under clean and cold flowing water for at least 10 minutes.

For injuries like sprains, twisting and contusion, the 'RICE' remedy should be

applied :

 Rest: Allow the victim to sit in a relaxed position.

 Ice: Apply an ice-pack to the injured part.

 Compression: After the ice-pack treatment, the injured part should be

massaged gently.

 Elevate: The injured part should be kept in a raised / elevated position.

b) State the scientific and eco-friendly methods of waste management.

Ans: The scientific and eco-friendly methods of waste management are as

follows:

 Separation and categorization of waste

 Composting

 Vermicomposting

 Safe landfill sites

 Land-fill method (for industrial solid waste management)

Answer 2

Answer:

True

Explanation:

A species is a group of individual organisms that interbreed and produce fertile, viable offspring. Organisms of the same species have the highest level of DNA alignment and, therefore, share characteristics and behaviors that lead to successful reproduction.
