During the process of vaccination, an attenuated pathogen is inserted into the body the organisms. The attenuated pathogen is able to provoke the primary immune response in the body of the organism without causing any harm.
Once the primary immune response is generated, the body creates a memory in form of antibody to the pathogen. After vaccination, if the pathogen infects, the body recalls the memory and generates a secondary immune response. The intensity of the secondary immune response is much higher than the primary one, so, as soon as the pathogen enter in the body, the antibodies against it are activated and result in defeating the infection.
For a better understanding purpose, the intensity of the primary and the secondary immune response is given in the figure:
Answer:
d. a vaccine causes the secretion of antibodies which remain in blood and fight the pathogen at the time of an infection.
B. are produced from two identical embryos
C. result from two eggs fertilized by two different sperms.
D. is wrong
B) sequence.
C) map.
D) contig.
Acontiguous stretch of DNA formed from overlapping DNA fragments is known as a contig. Contigs are a crucial component in DNA sequencing and genome assembly.
A set of overlapping DNA fragments that form a contiguous stretch of DNA is referred to as a contig. In molecular biology and genetics, contigs are used in the process of DNA sequencing to assemble larger sequences of DNA from smaller sequences or fragments. Creating a contig is a crucial step in genome assembly, and it is typically accomplished using computer algorithms that match overlapping ends of different DNA fragments.

The right option is D 6CO2 + 6H2O --> C6H12O6 + 6O2
This equation shows that carbon dioxide and water are used with light energy to produce glucose sugar and oxygen gas.
Photosynthesis is a process by which plants and other autotrophs use energy from sunlight to produce nutrients from carbon dioxide and water. Plants absorb water through the roots, carbon dioxide from the air, and light energy from the Sun, to produce glucose and oxygen.
The correct equation for photosynthesis is 6CO2 + 6H2O --> C6H12O6 + 6O2. In this complex process, carbon dioxide and water are transformed into glucose and oxygen with the help of sunlight.
The correct equation that represents the reactants and products of photosynthesis is option D: 6CO2 + 6H2O --> C6H12O6 + 6O2. In this process, carbon dioxide (CO2) and water (H2O) are the reactants which, when exposed to sunlight, get transformed into glucose (C6H12O6) and oxygen (O2), which are the products. While the equation seems simple, it represents a complex multi-step process that plants use to convert light energy into chemical energy.
