Answer:
Explanation:
A skeletal muscle cell is surrounded by a plasma membrane called the sarcolemma with a cytoplasm called the sarcoplasm. A muscle fiber is composed of many fibrils, packaged into orderly units.

Hypotheis:
<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>
- <u>A- Pepsin</u>
- <u>B- Amylase </u>
- <u> C- thermophilic enzyme</u>
Explanation:
Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.
Each enzyme provided has its own optimal temperature and pH values.
- Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
- Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4 glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
- Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH is typically low i.e. acidic due to the hydrochloric acid in digestive juices.
Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
Answer:
There are three castes in honey bees:
- drones
- workers
- queens.
Explanation:
There are three castes in honey bees:
- Drones-Male honey bees are drones. The head and thorax of the drone are bigger than the females.
- Queens-Honey bee queens are the species' reproductive women.
- Workers-Workers' sweet bees are generally non-reproductive women.
Answer:
CO 2 can be captured from the exhaust of a combustion process by absorbing it in a suitable solvent. This is called post-combustion capture. The absorbed CO 2 is liberated from the solvent and is compressed for transportation and storage. Other methods for separating CO 2 include high pressure membrane filtration,...
