Edward Jenner's smallpox inoculation experiment was based on his observation that some dairymaids who worked
with cows had suffered lesions on their hands, but that these dairymaids were immune to the more severe smallpox.
Which best explains why the dairymaids were immune to smallpox?
They did not interact with many people so they were not exposed to the pathogen.
They frequently washed their hands so they were able to wash away the pathogen.
They were exposed to cowpox, and the substance their body produced to fight cowpox also attacked smallpox.
O They breathed the air around the cows that carried an antipathogen in it that destroyed the pathogen.

Answers

Answer 1

From anecdotes he heard, Edward Jenner came up with the premise and conclusion that dairy maids could not get small pox because they had previously been exposed to the virus.

What was conclusion of Edward jenner in case of small pox?

He also came to the conclusion that small pox may be passed from one person to the next. Edward Jenner came to this conclusion based on stories he had heard about dairy maids being immune to smallpox.

In 1736, Edward Jenner met Sarah Nelms, a young dairy girl with small pox lesions. Edward Jenner then vaccinated an 8-year-old kid named James Phipps with material from Nelms' small pox lesion. James Phipps suffered a fever and became unwell, but he recovered completely after ten days.

Jenner infected the same boy with materials from a fresh small pox lesion a month later. There was no sickness in the boy.

When Edward Jenner was inoculated/vaccinated with matter from a small pox lesion, he came to the conclusion that he could acquire total protection from small pox.

Unicellular organism are one celled but multicellular organisms are made up of many cells.

Explain the difference between unicellular and multicellular organization of organisms?

As the name suggests, unicellular organisms are made up of only one cell and this single cell carries out all the essential functions that are needed for the survival of the organism like respiration, photosynthesis etc.

But in multicellular organization, the organisms are made of more than one cells and cells are grouped according to their functions. Each group is specialized for specific functions. Even in higher multicellular organisms the group of cells form specific types of tissues and further they form organs and organ systems which function more efficiently.

So ½(90m+50m) 45m

½ × 140 × 45

Which of the statements is true about heating up air in the lower atmosphere

Answers

Answer: Option (A)

Explanation:

The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.

This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.

This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.
