Answer: -70 mV
Explanation:
Assume a physiologist has inserted a microelectrode into a neuron when it is at rest. The voltage recorded at the arrow tip will be <u>-70 mV</u>.
Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).
Reference: Powell, K. Acid stops bacteria swimming. Nature (2003).
The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
Answer:
D) the incineration of all hazardous waste
Explanation:
The method of incineration is the most desirable way to reduce overall hazardous waste because which can detoxify and destroy certain organic wastes.
Some of the different types of incinerators are the multiple-hearth furnace, fluidized-bed incinerator, rotary kiln, and liquid-injection incinerator.
Hence, the correct answer is "D".
