Prokaryotic cells- Lack a membrane bound nucleus
Eukaryotic cells- Have a membrane bound nucleus
TIP: remember PROkaryotic= for NO membrane bound nucleus
The Anser would be [<u>Group 3]</u>.
Why Biotic: Is a Living thing so Fish, Consumer, Producer
The guidelines for making good and accurate observations are:
1. Standardise the experimental setup: Know the precision and the accuracy of the instrument used to make observations. Example, thermometer with a least count of 1°C cannot measure in fractional values.
2.Take careful measurements: Holding the instrument properly without causing any disturbance is the key.

Answer: C. Miller and Urey showed that inorganic compounds could combine to form the building blocks of living cells.
Explanation:
The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.
The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.
