the mouth is a part of the digestive system. cells in the digestive system are the most quick cells to be replaced. so taking a sample from it won't cause much problem, unlike you take it by cutting open your leg and taking a sample.
the lining of the cheek is the easiest to take rather than having to take it from somewhere else. and the cells in the mouth are alive, unlike skin cells that are dead.
conclusion : it is the safest, fastest way to get live animal cells
When animal cells are in fresh water for a long time cytolosis occurs and red blood cells explode.
When a student is studying fresh mounts of animal cells, they should first ensure that their workspace and tools are clean to avoid contamination. Using a sterile technique, they should carefully place a drop of the sample on a glass slide and cover it with a coverslip to prevent drying out. Students should then use a microscope to observe the cells, adjusting the focus and magnification as needed to examine cellular structures. It's also important to take notes and document any observations for future reference.
There are a few things students should do when studying fresh mounts of animals cells. Students should adjust the microscope.
The uterine lining builds-up in preparation for fertilization so that the zygote/embryo can implant itself into the uterine lining and then develop into a baby. Menstruation only takes place when fertilization doesn't take place, this occurs so the uterine lining is shed and can start a fresh next cycle so it can be ready for pregnancy again. If the uterine lining were to break down after fertilization a zygote/embryo wouldn't be able to implant itself or it would result in miscarriage.
The cells of the celery stalk are hypertonic to fresh water, causing water to move into the cells through osmosis, making them stiff. When placed in a salt solution, the cells become hypotonic, causing water to move out of the cells, resulting in a limp texture.
It sits in your mouth inbetween your teeth and cheek and soaks up the saliva. If there is THC in your cheek cells, it will be in your saliva. (Your cheek cells are replaced with fresh ones quickly. Don't consume THC for 3-4 days, and you will pass a mouth swab.)

It is the elimination of "old" inner lining of the uterus, so that a new "fresh" lining can be produced. Its importance is that an embryo can only implant on a new lining.
how many hydrogen fresh water animal has]
it can be
The thick lining is prepared by the nature,so that implantation of the zygote should be possible. If there is no fertilization, then this lining is shed away. You have fresh lining for the next month. After all generation next is very much important for the nature.

This could be the menstrual phase, when uterine lining sheds to start a fresh. Or it could be the fertile phase following menstruation.
I dont know what you are asking
Biologically, it is said that in menstruation the uterus 'weeps', as there is no pregnancy. The lining of the uterus is shed in the menstruation. Uterus is ready to have fresh lining of the uterine wall through next menstrual cycle.
its called the keehc please like comment and subscribe for more plus i love aqua fresh
because Fresh water enters easly in the plant cells by endo osmosis. Thus, it causes better growth to the plant.
