Answer:
The correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Explanation:
As they added sweet grape juice mixture the amount of sugar increased in the content and it is seen that more than 6 % of sugar decreases the rate of fermentation and alcohol concentration also decreases and a moderate amount of glucose concentration in the anaerobic environment increases the fermentation results in more alcohol production.
High sugar concentration decreases fermentation but increases cellular respiration in the yeast, as a result, it uses more sugar for its growth and produce CO₂ and H₂O so alcohol is not the by-product of cellular respiration. Therefore the correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Answer:
The correct answer is option b. "The receptor potential is carried by neuroglia".
Explanation:
Neuroglia is a term used to describe a class of cells which main function is to support the neurons. The term neuroglia include astrocytes, ependymal cells and oligodendrocyte. It is false to affirm that the receptor potential is carried by neuroglia, the receptor potential is carried out by the neurons.
The correct descriptions of each of the organisms are as follows:
Archaea:
- cells do not have a nucleus
- cells contain genetic material
- most inhabit extreme environments.
Bacteria
- cells do not have a nucleus
- prokaryotes
Eukarya
- eukaryotes
- cells have a nucleus
- many are multicellular
- cells have membrane-bound organelles
- plants
Archaea and Bacteria
- cells do not have a nucleus
- cells contain genetic material
- prokaryotes
All three domains
- cells contain genetic material
<h3>What are living organisms?</h3>
Living organisms are those things that have life in them.
Living organisms are classified into the following domains:
- archaea,
- bacteria, and
- eukarya
A common feature of all three domains is that they all have genetic material.
In conclusion, living things are classified into three domains.
