Answer:
Explanation: When you have a slow digestive system, a condition known as gastroparesis or delayed stomach emptying, these muscles don't work properly. They either contact too slowly or don't work at all and, as a result, your stomach doesn't empty properly.
Eating slowly also helps our digestion. Think of digestion as a chain reaction. As soon as we see, smell, or think about food (step 1), we start salivating to prepare for putting that food in our mouth (step 2). Saliva contains enzymes that break the food down, and moistens the mouth for easier swallowing.
Viruses aren’t normally considered organisms
Answer and Explanation:
1. Amino-acid sequence is the primary structure of a protein
2. Alpha helices, beta sheets and coiled coils refers to the protein folding and they represent the secondary structure of a protein
3. Protein ensemble formed by alpha helices, beta sheets and coiled coils represent the tertiary structure of a protein
4. Macromolecules with multiple polypeptides form globular or fibrous protein structures (quaternary structure)
Passive diffusion is a form of passive transport and a type of diffusion by which particles from a high concentration gradient passes through a biological membrane to a low concentration gradient. Diffusion, or simple diffusion on the other hand, is the passage of molecules without the need of a membrane.
Answer:
65 L
Explanation:
It is assumed that the temperature is constant at both the sea level and the altitude.
<em>According to the gas law, at constant temperature, the pressure of a gas is inversely proportional to its volume.</em> Mathematically:
P1V1 = P2V2 where P1 = pressure at initial volume, V1 = volume at initial pressure, P2 = pressure at final volume, and V2 = volume at final pressure.
In the illustration, V1 = 15 L, P1 = 100 kPa, V2 =?, P2 = 23 kPa
V2 = P1V1/P2 = 100 x 15/23 = 65.22 L
<u>The volume of the hot air balloon at the altitude would be 65 L</u>
