Question

ANSWER THE FOLLOWING QUESTIONS IN LONG :-


1. The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336.0

km? Calculate the speed of the car in km/min during this time. Express the speed in km/h

also.


2. List the similarities and differences between aerobic and anaerobic respiration.


3. Describe the different methods of asexual reproduction. Give examples.

4. Explain the difference between sea breeze and Land breeze.

5. Explain in detail about the various process involved in nutrition in animals.​

Answer 1

Answer:

1) Distance =57336.0km−57321km=15km

Speed in km/min =15km/20min=

60min

=(15×3)km/hr=45km/hr.

2) Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. ... Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.

The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration

3) There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding. Binary fission occurs when a parent cell splits into two identical daughter cells of the same size. ... Budding in yeast .

4) Land breezes usually blow dry winds. While the sea breeze contains more amount of moisture due to the particles absorbed from the water bodies. Hence, both the land breeze and sea breeze occur near water bodies. But, the pace of the land breezes' is slower than compared to the sea breeze.

5) There are five steps in the process of Nutrition in animals. These are: Ingestion, Digestion, Absorption, Assimilation and Egestion. Ingestion: is the process of taking food in to the body or 'eating of food' by the animal.

Answer 2

$\textbf{Question -}$

• The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h.

$\textbf{Solution -}$

• Ordometer reading car at 8:30 am = 57321.0 km
• Ordometer reading car at 8:50 am = 57336.0 km

Or Distance travelled :- (57336.0 - 57321.0) km

• 15.0 km
• 8:50 am - 8:30 am
• 20 min

Speed = Distance/time :- 15 km/20 min

• 0.75 km/minmin

And Speed in km/h :- 0.75 km/1/60 h

• $1min \: = \frac{1}{60h}$
• $0.75 \times \frac{60km}{n} = \frac{45km}{n}$
