Answer:
Option A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

Based on the data, what would you conclude about the drug, explain if it worked or not and give your reasoning.?
Answer:
I don't know the data but you can infer the drug/nondrugged mice had a bigger/smaller litter based on the numbers from the data
Explanation: you would have to include the data so we can give you the answer.

what is the out group of this cladogram
Answer:ur answer is protozoa
Explanation:
In cladistics or phylogenetics, an outgroup is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study, and is distinct from sociological outgroups.
The out group in this cladogram is protozoa that is distantly related to the other organism s in the given cladogram.
The out group is a creature that is only distantly connected to the other creatures on the cladogram. The out group, which is commonly assumed to represent the ancestral situation from which the organisms in the cladogram later evolved, contributes to the tree's roots.
The organisms in the in-group are connected to one another. The cladogram is founded on the introduction of a distantly related creature known as the out group. The out group is frequently represented by a single branch on the cladogram.
Out group is an evolutionary phrase that refers to a taxon or lineage that is not part of the taxon group being examined.
Thus, the out group in this cladogram is protozoa.

The esophagus, a tube that carries food to the stomach, is constantly being scraped as food travels through it. Why does the esophagus not deteriorate through a person’s lifetime? Cells can anabolize the food prior to entering the esophagus. Cells are constantly dividing and replacing old or damaged cells. Cells promote a fluid to build up along the esophagus to reduce friction. Cells build a type of protein called enzymes that act as an armor.
Cells are constantly dividing and replacing old or damaged cells.

Which of the following is true of red blood cells? A. They live for only 120 days. B. They have multiple Nuclei. C. They live for only about 20 days. D. Once created in bone marrow, they circulate for our lifetime.
A. They live for only 120 days is correct. They are created in the bone marrow and destroyed in the spleen "red blood cells graveyard"
B. They have multiple Nuclei. Red blood cells don't have a nucleus but some can present structures called Jolly's bodies that are small pieces of the nucleus that they lost in the differentiation process
C. They only live for only about 20 days. No, red blood cells live for about 120 days
D. Once created in bone marrow, they circulate for our lifetime. Again, they have a limited lifetime
*PLEASE ANSWER TY* Which gas makes up the majority of air pollutants? a.) sulfuric acid b.) sodium hydroxide c.) carbon monoxide
Answer:
carbon monoxide
Explanation:
sulfuric acid is litterally acid
sodium hydroxide..... common now
Carbon monoxide (c.) is the gas that makes up the majority of air pollutants.
What is carbon mono oxide?
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, coal, and wood. It is a highly toxic gas and can be harmful to both humans and animals.
When inhaled, carbon monoxide enters the bloodstream and binds to hemoglobin, the molecule responsible for carrying oxygen to body tissues. This binding affinity is much stronger than that of oxygen, resulting in reduced oxygen delivery to organs and tissues. As a result, exposure to high levels of carbon monoxide can lead to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, loss of consciousness and death.
Carbon monoxide is a significant air pollutant, often found in areas with heavy traffic, industrial emissions, and improper ventilation. It is important to have proper ventilation systems and to use carbon monoxide detectors to minimize the risk of exposure to this dangerous gas.
