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.

Follicle-stimulating hormones (FSH):

</span> <span><span>· </span><span>In females-</span> stimulates the growth recruitment of immature ovarian follicles in the ovary</span>
<span> Luteinizing hormones (LH):</span>
<span><span>· </span>In males- stimulate the Leydig cells to produce testosterone</span>
<span><span>· </span>In females- stimulates theca cells for estradiol production</span>
Those are only some of the functions of those hormones. <span>Adrenocorticotropic hormones are hormones produced by pituitary glands which also indirectly have an influence on the reproductive system (male and female).</span>
Answer:
This is what my teacher gave me to figure out the amino acid sequences. And it was confusing at first, but I eventually got it. So, hopefully it will help you too. Let me know if it helps. Or if it does not so that I can try to be more helpful.
Explanation:
This is a codon wheel/chart, whatever you want to call it. I attached the codon chart/wheel. So that you can see it. Let me know if you can not see it.

The correct answer is: B) As land plants became more complex, animal life did as well.
This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.
So, plants were one of the earliest organisms to leave the water and colonize land.
