Answer:
Answer
Explanation:
The wind and water can break down the landscape and affect its physical formation. Water for example can break down rocks and make a ditch from 1 foot deep to 6 feet deep.
* 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.
Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, watches TV 2.0h, plays tennis 1.5 h, and runs 0.50h daily, If the metabolic rate for sleeping is 70 J/s, for sitting is 115 J/s, for engage in light activity is 230 J/s, for watching TV is 115 J/s, for playing tennis is 460J/s and for running is 1150 J/s.
Answer:
171.8 W
Explanation:
The Average metabolic rate can be deduced by multiplying each entity performed at a some particular hour of time with their corresponding energy, all divided by 24 hours.
Average metabolic rate = 
= 171.8 W

Answer:
As a cell prepares to divide, it must make a copy of each of its chromosomes. The two copies of a chromosome are called sister chromatids.
