Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.
Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.

<span>There are three major groups of mammals, categorized on the basis of their method of reproduction. Monotremes lay eggs to have children instead of having the mother bear them. The second type of mammal is the marsupial, which are non-placental animals who carry their young in their pouches. Eutherians are the third group who are placental mammals.</span>
Answer:
The rate of photosynthesis was more than the rate of respiration
Explanation:
Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.
<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>
