The animal cell and the plant cell have some organelles in common but there are some organelles that belong to only one of the cell. In the question given here, mitochondria, cillia and ribosomes are found in both plant and animal cells. The cell wall is found only in the plant cell. So, the correct option is B
Hope that help!
The addition or removal of heat changes the temperature of an object. The temperature can cool down or it can warm up.
Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
