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.

I believe it’s hemoglobin
Answer:
Explanation:
Synovial joints, often referred to as joints, are composed of two or more bones with a gap between the opposite bone surfaces, connected only by the fibrous connective tissue membrane around them. The synovial joint is the main form of bone joint and has great mobility.
<em>The preclinical trial of therapy against Alzheimer’s disease (AD) is an essential and complex step. It functions as a bridge between candidate discovery and clinical development since it constantly provides us with new information on pieces of the complex AD puzzle. Analysis of this information is likely to reveal patterns of pharmacological interactions instead of the single potential drug target. A group of well-trained, knowledgeable medicinal biochemists in Alzheimacy with decades of experience in preclinical research are willing to work with leaders and scientists from academia, pharmaceutical and biotechnology companies around the world to further develop more promising and stringent therapeutics for AD.</em>
