One example of how applied science has had a direct effect on daily life is the presence of vaccines. Vaccines to prevent diseas
Mashutka [201]

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.

All the following are true of the movement of Earth's atmosphere except :
zheka24 [161]

Answer:

All  are true of the movement of Earth's atmosphere except :

d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.

Explanation:

  • When gases heat up, their volume increases and  density decrease.
  • A decrease in density causes a substance to become lighter.
  • Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
  • So, it will move up.
  • The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
  • Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
