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.
<h3>
What was conclusion of Edward jenner in case of small pox?</h3>
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.

Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

25% is the approximate production efficiency of this animal
Explanation:
Given ,
A ladybug eats 200 J of plant material
100 J is eliminated as feces
75 J are used in cellular respiration,
Now,
The approximate production efficiency of this animal :
200 - (100 +75) = 25 %
