First, let's distinguish active from passive immunity:
- Active immunity occurs in a direct exposure of individuals to live pathogens. The result is a development of a disease. After that, individuals acquire immunity to the disease.
- Passive immunity is induced by vaccines with antibodies for a disease, so the disease does not develop.

<span>a. ACTIVE IMMUNITY - Bill had a disease, so it must be active immunity.
</span>b. PASSIVE IMMUNITY - Bill got a vaccine and a disease did not develop, so it must be passive immunity.
c. <span>PASSIVE IMMUNITY - Although, 3-month-old daughter did not get a vaccine, she has mother's antibodies from the milk so she will not develop a disease.</span>

<u>Explanation:</u>

Background Knowledge:

DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.

Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.

The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.

Structural region is the region present between the promoter and terminator.

  • Using the analysis of RNA developed by Carl Woese, scientists are now able to classify  the human evolution
  • living things based on genetic information instead of expressed characteristics.
  • Genetic  information is more specific and can give clues as to the evolutionary ancestry of  organisms.
  • That is the reason adding of various domains in previous system of classification is allowed for a comparison of species genetic code

How to zoos affect the nitrogen cycle
SpyIntel [72]
<span>As humans change the way we live on the planet, the way that nitrogen moves around the Earth also changes. Nitrogen atoms may seem small enough to be easily overlooked. We look right through the ones in the air, do we not? Yet recent changes in the nitrogen cycle are causing a very noticeable effect on natural environments and human health. Lakes are clogged with aquatic weeds. Dead zones have formed in areas of the oceans where animals can not survive. Air pollutants that contain nitrogen are decreasing air quality and greenhouse gases that contain nitrogen are becoming more common.</span>
