Answer:
The inflow of sodium ions.
Explanation:
The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.
The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.
Thus, the answer is inflow of sodium ions.
Answer:
Explanation:
Bacteria become 'factories' that produce a large number of copies of the recombinant DNA. There are several reasons for the use of bacteria as the host in the recombinant DNA technology. They are; Bacterial cells are easy to grow, maintain, and manipulate in a laboratory.
Answer:
C. Atoms can be used over and over in different molecules
Explanation:
When different compounds enter the stomach, they undergo a series of chemical reactions and are broken down. They are then used for new metabolic processes. For example, if glucose was broken down into pure Carbons, they could then react and form other molecules as needed by the body.
Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.

Answer:
B) Nucleotide
Explanation:
This is because Nucleotides are made up of three things: Phosphate, Sugar, and a Base. Nucleotides are what make up DNA and RNA, and are considered the basic building blocks of DNA and RNA. To get a little off topic, the 4 bases types of bases are adenine, thymine, cytosine, and guanine.
