Answer:
Locomotion and feeding
trapping dust
Explanation:
Paramecium is an organism that belongs to kingdom protoctista. They swim in water through beating of the cilia. They also feed on tiny organisms that are swept into the oral groove through beating of the cilia.
During gaseous exchange in mammals, along the nasal passage are cells with cilia that trap dust particles and beats to move mucus and dust trapped up to the larynx.
Answer:
A. pH
Explanation:
Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.
However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.
The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
<span>In one sample, the potatoes that have more sugar will also have more water that will diffuse into them. Potatoes are hypertonic in relation to pure water,simply put, they will gain extra water weight as well as displace more water than potatoes that are lower in sugar. In a separate sample, potatoes that have a higher concentration of sugar will also lose far less water due to their lack of hypotonic nature. Those with lower sugar will easily loose more water.</span>
