Answer:
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration
Answer: goblet cells
Explanation:
The goblet cells are typically found scattered inside the epithelial lining of the organs for example the respiratory and intestinal tracts. They can be seen inside the bronchi, trachea, small and large intestine, also in the conjunctiva of the eyelid.
The goblet cells are responsible for the secretion of the mucus in order to protect the mucous membrane. This is accomplished when the goblet cells secrete the mucins, the mucins are the large glycoproteins that are formed by the carbohydrates.
Answer:
B) Thin platelets with chain folds at the faces
Explanation:
Crystalline polymer is folding together of molecular chain in an ordered way to form lamella. Polymer crystallize after cooling from evaporation of solvent. It affects the properties of the polymer such as thermal property.
Polymer on freezing becomes disorder forming an amorphous solid.
Biologists use plasmids to join two DNA molecules together.
1. Trenches
2. Mountain/Volcano formations as well as earthquakes
3. Earthquakes and tsunamis
4. It has made formations like the Marianas Trench, The Ring of Fire, and the Haiti earthquake
