Scientific knowledge may be open to change because our human knowledge is limited. Discoveries are made all the time opening up explanations to things that contradict what we previously thought to be true. Because of this, we have come to be open to change scientific knowledge in case new information is discovered that can shed light on the unknown.
Take our solar system for example. We know our solar system to be heliocentric, meaning that our sun is the center of it. Used to, the geocentric model of our solar system was widely accepted that the Earth was the center of the solar system.
Even the theory that Earth used to be flat. Once we had technology to take pictures from space and prove for sure that the earth is round, some people believed that it was flat.

The correct answer is D.
The decrease in white blood cell count in the human blood is known as leukopenia. This disease affects the body's ability to counter diseases and infections. A low blood count can result in the affected person becoming very susceptible to infections.
The primary function of white blood cells in the body is to fight and neutralize infections. Once the white blood cell count significantly dips below the normal level, the body's defense is compromised and so becomes susceptible to infections.
Answer: Activation Energy
Explanation:Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

The correct answer is option B
The energy efficiency can be defined as the output of energy to the input of energy.
As the efficiency of energy is increasing then the consumption of electricity will be less because previously the energy was used more due to loss of energy.
But now the energy will not be lost in the form of heat or friction and the cost of energy will be less.
