Answer:
used to observe small objects, even cells
Explanation:
The image of an object is magnified through at least one lens in the microscope.
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
A stored form of carbohydrate in animals' muscle and liver is glycogen.
Glycogen is a polysaccharide (starch) made of repeating units of glucoses bonded together.
Answer:
1) As the body's chemical messengers, <u>hormones</u> transfer information and instructions from one set of cells to another.
2) A <u>gland</u> is a group of cells that produces and secretes, or gives off, chemicals.
3) Hormones are released into the bloodstream via small tubes called <u>duct.</u>
4) Hormones find their way through the blood to their <u>targeted/respective </u>cells.
5) Each hormone is a differently shaped key that will only fit into the correct <u>receptor</u> lock.
Answer:
Water will diffuse into the cell.
Explanation:
As the NaCl conentration in cell is greater then in water so water will diffuses into the cell and NaCl will move out of the cell
