Habe einen dna Test gemacht und dort kam 35% zentral Asien raus. Obwohl meine Verwandtschaft von dort diese typischen Ost-asiatischen Gesichtszüge haben, sehe ich nicht so aus wie die. Wie kann das sein?
So this is very complicated: If 2 identical twin pairs (2 women and 2 men) marry each other (man woman). So then they are 2 married twin couples. let's say both couples have children, wouldn't they be genetic siblings and look the same? because the parents all have the same genes. by the way: are…
Welche steine gibt es die unter Uv licht leuchten und könntets mir eine websitevorschlagen wo man diese bekommt ? Danke
Interessiert mich voll, weil wir haben uns über das thema unterhalten, und wurde uns interessieren welchen Grad die mit mir sind, und ob da noch blutverwanschaft gibt. wir sehen uns als Geschwister an.
Weiß jemand wie alles beschriftet heißt ?nicht auf die Buchstaben achten eher auf die Pfeile ich hab mir Anatomie vom Herzen auf Google angeschaut dort sehen die aber anders aus also es würde mir wirklich helfen da es das letzte ist was ich brauche um in der Arbeit eine gute Note zu schreiben

Plasmolysis and deplasmolysis are processes in which the cell wall of a plant cell and the cell membrane are drawn together or unfolded under the influence of external factors. Plasmolysis occurs when the cell dehydrates and the cell wall and the cell membrane contract. Deplasmolysis, on the other hand, occurs when the cell is again hydrogenated and the cell wall and the cell membrane unfold again.
Diffusion and osmosis are processes in which substances (for example water, salts) move through a membrane. In the diffusion process, the substances move from a high concentration range to a low concentration range until the concentrations on both sides of the membrane are the same. In the osmosis process, the water moves from a solution with a low concentration (diluted solution) to a solution with a high concentration (concentrated solution) until the concentrations on both sides of the membrane are the same.
In connection with plasmolysis and deplasmolysis, diffusion and osmosis play an important role. During plasmolysis, the water moves out of the cell through the cell membrane to the outside, which leads to dehydrogenation of the cell and to the formation of the cell wall and the cell membrane. During the deplasmolysis process, the water is diffused back into the cell, which leads to a hydrogenation of the cell and to the development of the cell wall and the cell membrane. Osmosis also plays a role in both processes, since the water moves through the cell membrane and influences the concentrations of water and other substances on both sides of the membrane.
In short, the terms can be explained as follows:
Hope this helps in preparing for organic work!
Thank you for your help!!
and what is the semi-membrale dings for?
