Before there was any life on earth, which gas was absent from earth’s ancient atmosphere?A. nitrogen

B. ammonia

C. oxygen

D. methane

Answers

The answer is C. Oxygen.
Oxygen is the most important gas that living things need to be able to survive especially human. Thus absence of oxygen is absence of life as well.
Plants and animals also needs oxygen to be able to live.

Answer:

It is C. oxygen

The energy transformations in a car’s engine are an example of multiple transformations. True or False?

Answers

Answer;

The above statement is true.

The energy transformations in a car’s engine are an example of multiple transformations.

Explanation;

  • From the law of conservation of energy, energy can neither be destroyed nor created but can be transformed from one form to another.
  • Energy transformation occurs when a transducer or a machine converts energy from one form to another. Examples of traducers includes, bulb, generator, etc.
  • Examples of multiple energy transformations include those in a car engine, where; internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy then transformed mechanical energy which accelerates the vehicle.
A.TRUE...........................

Energy frequently changes form as it moves through biogeochemical cycles. Energy transfers in lightning fixation differ from those in photosynthesis because in lightning fixationradiant energy transforms into chemical energy; in photosynthesis, electrical energy transforms into chemical energy.

electrical energy transforms into chemical energy; in photosynthesis, chemical energy transforms into electromagnetic energy.

electrical energy transforms into chemical energy; in photosynthesis, radiant energy transforms into chemical energy.

radiant energy transforms into chemical energy; in photosynthesis, chemical energy transforms into radiant energy.

Answers

Energy transfers in lightning fixation differ from those in photosynthesis because in lightning fixation electrical energy transforms into chemical energy; in photosynthesis, radiant energy transforms into chemical energy. Thus, the correct option is C.

What is Photosynthesis?

Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.

During lightening, the form of electrical energy is transferred into heat or thermal energy with an intermediate of chemical energy, while during photosynthesis, plants capture sunlight in which radiant energy of sunlight gets transferred into chemical energy.

Therefore, the correct option for this question is C.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection

Answers

The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.

The correct answer is:

Option B. Disruptive selection.

This can be explained by:

  • Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.

  • This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.

  • For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.

Therefore, disruptive selection will lead to increased phenotypic and genetic variation.
