Answer:
Carbohydrates can be described as biological molecules which are made up of carbon, hydrogen and oxygen.
Simple carbohydrates are known as monosaccharides. Example of monosaccharide includes glucose and fructose. Two molecules of monosaccharides can join to form disaccharides. Example of disaccharide includes maltose. When three or more monosaccharides join they form polymers known as polysaccharides. In this way, simple carbohydrates form larger molecules or polysaccharides. Examples of polysaccharides include starch, glycogen, cellulose etc.
Answer:
F = 25000 N
Explanation:
It is given that,
Pressure exerted by the object, P = 1000 Pa
Area of cross section, A = 25 m²
We need to find the force exerted on an object. The pressure exerted by an object is equal to the force acting per unit area. So,
So, the force exerted on an object is 25000 N.
Note that Facilitated diffusion , Active transport and Osmosis are three different ways of transporting substances across the cell surface membrane.
Facilitated diffusion is the movement of a substance from high to low concentration , similar to simple diffusion , but due to the complexity of the cell surface membrane , polar molecules and ions cannot just pass like that , so they pass through specific carrier and channel proteins in the cell surface membrane and so we call it facilitated diffusion.
For Active transport , it's the movement from low to high concentraion using energy from ATP
For Osmosis , it's totally different . You only name osmosis when its all about water . Its the net movement of water from high water potential to low water potential through partially permeable membrane .
If you're doing AS , you'll be familiar with Endosmosis and Exosmosis.
<span>Triglyceride. Triglycerides are organic molecules found in fat cells like the subcutaneous tissues. They are the main constituents of body fat in humans and other animals; they are a type of lipids found in the blood which the body uses for energy in cases of starvation.</span>
