A teacher writing to a confused student.
bacteria are microscopic (very tiny) organisms that are unicellular (made up of a single cell). One fundamental difference is that bacterial cells lack intracellular organelles, such as mitochondria, chloroplasts, and a nucleus, which are present in both animal cells and plant cells.
Answer:
chromosomes
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Interdependence. Animals in a food chain/web are dependent on eachother for survival or death
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.
