Question

(2) Distinguish the following.


1) Aerobic and Anaerobic Respiration


2) Convex lens and Concave lens​

Answer 1

Answer:

A concave lens is thinner in the middle and thicker at the edges. A convex lens is thicker in the middle and thinner at the edges. Used in the camera, focus sunlight, overhead projector, projector microscope, simple telescope, magnifying glasses, etc. It is also used for the correction of the problem in long sight

the pictures attached are the answer of 1

Answer 2

Explanation:

concave mirror

# reflecting surface is covered in words

# polishing is done on outer surface

# it produces both real and virtual image

convex mirror

# reflecting surface is covered outwards

# polishing is done on inner surface

# it produces only virtual images

AEROBIC RESPIRATION

# AEROBIC RESPIRATION TAKES PLACE IN THE PRESENCE OF OXYGEN

# complete breakdown of food occurs in it

# the end products of carbon dioxide and water

# it produces a considerable amount of energy due to complete oxidation of food molecules

ANAEROBIC RESPIRATION

# anaerobic respiration takes place in the absence of oxygen

# in complete oxidation of food occurs

# the end product may be ethanol alcohol and carbon dioxide or lactic acid

# much less energy is produced due to incomplete oxidation of food
