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>
You did not post the scenario
Im not sure if this is right or not but i think it might be C.
Hope its right!!!!
Answer:
A. They do not use up any energy finding mates.
Explanation:
The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.
For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates
Therefore in the given case the correct option is A.
Meiosis differs from mitosis in the number of chromosomes in each ending cell. In addition, one of the purposes of meiosis is to reduce the chromosome number in each cell by half and meiosis contains two rounds of division which is meiosis I and meiosis II and ends with four gametes that are not the same genetically.
