Explanation

The first fossils of prokaryotic (bacterial) cells are known from 3.5 and 3.4 billion years ago. 

while 

The eukaryotes developed at least 2.7 billion years ago, following some 1 to 1.5 billion years of prokaryotic evolution.

Explanation

• Maltose is used to make Alcohol
• **
• Maltose is the main sugar used in the brewing process.
• It is broken down during the malting process and it is this maltose that provides the energy for yeast to turn into alcohol.
• Malted barley is also a key ingredient in most beers as it helps to provide body, head retention, and flavor
  

Explanation

• In insectivore plants, the insect is digested by: bacteria
• **
• The insectivorous plants digest the prey chemically using enzymes and bacteria.
  

Explanation

 The amount of heat required to vaporize one mole of a liquid at its boiling point is called Molar heat of vaporization. 

"Molar" refers to one mole of a substance, and "vaporization" means the process of turning a liquid into a gas. 

Explanation

The presence of a dielectric material between the plates of a capacitor reduces the electric field by a factor called the dielectric constant 𝐾

The electric field E in a capacitor with a dielectric is related to the field E0 without the dielectric by:

E= E0/K

​When the dielectric material is removed, the dielectric constant K becomes 1 (for vacuum or air), and the electric field reverts to its original strength, increasing by a factor of 𝐾

Thus, when the dielectric is removed, the electric field increases.

Explanation

 Pyramidal molecular structure is typically found in molecules like ammonia (NH₃), where there is a central atom with lone pairs and three bonded atoms.

Explanation

Sickle cell anemia is caused by a mutation in the gene that codes for the beta-globin chain of hemoglobin,

where valine is substituted for glutamic acid at the sixth position, causing the red blood cells to assume a sickle shape.

Explanation

The temperature within 10 km of the Earth's core is approximately 4000 Kelvin (K).

At such depths, the temperature is incredibly high due to the immense pressure and heat generated by the Earth's core.

Explanation

The hydrolysis of fats is brought about by lipase enzymes.

Lipases are a class of enzymes that catalyze the hydrolysis of fats into fatty acids and glycerol.

Explanation

Science is the systematic study of the nature and behavior of the material and physical universe, based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.
