Does meiosis produce most of the body cells?
The only body cell that can under go meiosis, is sex cells, or gametes. Meiosis is the process in which cell division occurs to produce only reproductive cells. Autosomes, or body cells that do not determine gender, under go a cell division called mitosis, but never through the process of meiosis, except for reproductive cells.
If you observe a drop of blood under a microscope which cells would you be observing?
Blood cells. The largest compartment of blood cells are the red blood cells (also called erythrocytes), but you would also see white blood cells (including lymphocytes and phagocytes) and some platelets.
What is a substance that carries electricity under certain circumstances but not under other circumstances called?
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
British scientist who first observed cells under a microscope?
Robert Hooke discovered cells under a microscope in 1665. He took a sliver of cork and called the small encasements he saw, cells. They were dead cells, though. The first person to see living cells, was a man named Anton van Leeuwenhoek. He took pond water and observed that under a microscope.
What type of cells go through mitosis?
All somatic or body cells can undergo mitosis. But only mature RBC and the cells that produce sex cells are not able to divide through mitosis.We had learned that nerve cells and other special cells can't under mitosis but new research says otherwise.
What makes your hair grow?
The keratin made by the hair follicle cells makes long fibers. The cells, growing just under the scalp, eventually die, leaving the keratin behind. This keratin, combined with the keratin left by many other cells, emerge from your scalp as hair.
What are the cells called under the sea?
Cells...
What layer of the skin contains dead cells?
Dead skin cells are called keratin and are usually packed on the palms of our hands and the soles of our feet. They usually stay there and sometimes flake off. There is keratin on skin in general, and they just fall and is rubbed away. Unless you scrub off the keratin, it remains on the surface of our skin (epidermis).
Where does the epidermis grow from?
The epidermis forms from key specialised stem cells found deeper under the outer layer. These stem cells are found in or on top of the dermis and grow into the epidermis. These cells in grow in layers and as the layers age, the cells undergo a process called 'keratinisation' almost completely changing into the protein keratin. The last part of the cell that is converted is the nucleus.
A hard protein material found in the epidermis?
skin's most apical layer is full of keratin the tight jxn's holding the stratified squamous epithelium together use claudin and occludin there are a few more cellular jxn's that use other proteins as well there is type IV collagen laminin and proteoglycans in the basal lamina under the epitheluim then there is LOTS more collagen in the loose and dense connective tissue underneath. hope that helps!
Do dead skin cells make up hair?
Yes its true that hair is dead skin cells but it grows wow just like your nails to what a paradox.
Column like cells that lie just under the epidermis?
Oddly worded question. Is the question supposed to read: What are the cells under the epidermis called? if so then the answer is that the cells under the epidermis are the dermis cells (connective tissue cells that connect the epithelium to the muscle)
Robert Hooke and the Hooke law?
Hooke discovered cells when he examined cork under his homemade microscope.
Do cells have a dark round spot in them?
Cells can be stained in laboratory setting for contrast and better visibility under a microscope. One type of staining is called a gram stain. The cells take up the dying agent(s) in varying degrees, and often times, the nucleus of the cell stains darker than other cellular components. When viewing the stained cells under a microscope, it is possible to identify the cells nucleus by the presence of an elliptical, oval, or elongated darkened spot.
Are your fingernails made out of the same material as your hair?
No. Nails are made of a protein, keratin, while teeth are composed of enamel, and tissues, dentin, pulp, and cemetum. The only live part of the nail is beneath the epidermis, where the growing occurs. Teeth are very much alive. Enamel, the outer portion of a tooth, is mainly hydroxyapatite. Dentin more porous, and is composed of a variety of organic materials and water; at the center of the tooth is the pulp, which is generally called the nerve of the tooth, housing blood vessels and nerve cells. Cementum is the composition covering the root of the tooth, created of a mix of hydroxyapatite, collagen, and water.
Why do cells come from other cells?
All cells come from other cells because we all started out as a single fertilized egg. As we under go miosis, the single cell divides and divides. The cells split and reproduces the DNA nad chromosomes and splits. The process goes on and on and never stops.
What is a substance that carries electricity under circumstances but not under other circumstances is called?
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
