Use of fossil fuels has increased the total amount of carbon in the carbon cycle.
nika2105 [10]

The correct answer is option a. true.

The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.

The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.

Ratling [72]

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

  • Lytic cycle
  • Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

basis of limited evidence as a starting point for further  
 investigation. 
 And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general 
 theory
 .The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.
