Answer:
Aerobic to lactic acid fermentation pathway
Explanation:
ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.
Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.
Answer:
IgE
Explanation:
Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.
They are known to be produced by produced by plasma cells (white blood cells).
Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.
In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
Your answer is A: these two organisms have the same amino acid sequences, which suggests common ancestry
Answer:
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Explanation:
- Fossil fuels such as coal, petroleum and natural gas are produced and stored in the geosphere. i.e. the part of the Earth that includes the Earth's interior, landforms, rocks and minerals.
- Fossil fuels, extracted from the geosphere are burned to generate energy.
- Combustion of fossil fuels releases the stored carbon into the atmosphere in the form of carbon dioxide.
The only way invertebrates fight diseases is through excretion. Excretion is a process through which metabolic wastes and toxins are eliminated from a specific organism.
