M. J. Schleiden:
In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)
<h3>
What is cell?</h3>
All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.
His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.
Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.
Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.
His experiment:
Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

The results show that fish are GMO when they fluoresce at night, GFP fish produce colored offspring when germinal cells are modified and conclusions indicate that transgenesis is viable.
<h3>What is the GFP protein?</h3>
The Green fluorescent protein (GFP) is a protein used in molecular biology to produce genetically modified organisms (GMOs).
The GFP gene can produce stable fluorescent offspring if the transgenesis technique modifed the germinal line.
In conclusion, we can conclude that fish were genetically modified because they express the GFP protein and produce fluorescent offspring only when the germinal line was modified.

The fallopian tube is the structure of the body where muscular tubes are ciliated lining which constantly moving. It leads from the ovaries of a female mammal up to the uterus via the uterotubal junction.
The work of fallopian tube is to enable the passage of egg cells to the uterus from ovaries. Fallopian tube has a cross-section which shows the four distinct layers which are lamina Provia innermost muscle, subserosa, and serosa.
Answer:
The excessive alcohol consumption of the mother.
Explanation:
Alcohol consumption during pregnancy harms the developing baby, the foetus. This is because alcohol passes from the mother's blood to the baby's blood and this affects the growth of the baby's cell.
This causes severe damage to the cells of the brain and the spinal cord.
FASD - Fetal Alcohol Spectrums Disorder is characterised by growth and developmental problems and it can range from mild to severe.
Example is the baby having small head, narrow eye and behavioural problems later in life.
