Answers

Answer:

Argon

Explanation:

Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.

is asthma is cased by virus

Answers

Answer:

Explanation:

Asthma is characterized by spasmotic contraction of the smooth muscle of the airways, by increased production of an abnormally viscous mucus by bronchial mucous glands, and, in severe attacks, by airway obstruction from mucus that has accumulated in the bronchial tree. This results in a greater or lesser degree of difficulty in breathing. One approach to classifying asthma differentiates cases that occur with an identifiable antigen, in which antigens affect tissue cells sensitized by a specific antibody, and cases that occur without an identifiable antigen or specific antibody. The former condition is known as extrinsic asthma and the latter as intrinsic asthma. Extrinsic asthma commonly manifests first in childhood because the subject inherits an atopic characteristic: the serum contains specific antigens to pollens, mold spores, animal proteins of different kinds, and substances from a variety of insects, particularly cockroaches and mites that occur in house dust. Exacerbation of extrinsic asthma is precipitated by contact with any of the substances to which sensitization has occurred; airway obstruction is often worse in the early hours of the morning. The other form of asthma, intrinsic, may develop at any age, and there may be no evidence of specific antigens. Persons with intrinsic asthma experience attacks of airway obstruction unrelated to seasonal changes, although it seems likely that the airway obstruction may be triggered by infections, which are assumed to be viral in many cases. Asthma attacks may be precipitated by food. For example, in small children, sensitivity to milk may stimulate an attack, and, in some adults, sensitivity to sulfite compounds found in some foods and wine may stimulate an attack. A subgroup of asthmatics are so sensitive to aspirin (acetylsalicylic acid) that ingestion of this chemical may lead to a life-threatening attack.

Answer:

No, not necessarily

Explanation:

Asthma isn't necessarily caused by a virus or a pathogen. It can be genetic or environmental, meaning that it can be passed down through family members, or it can result from an environmental factor, such as allergies or poor air quality.

Life need water. Its special features support many biological functions. First, water is a universal solvent, permitting chemical reactions and nutrient delivery in living organisms. Second, it facilitates metabolic reactions, ensuring biological activities. All organic compounds—carbohydrates, lipids, proteins, and nucleic acids—need water to function. It helps DNA and RNA transmit genetic information by forming their backbones.

Photosynthesis, which turns light into chemical energy, requires water. This process splits water, releasing oxygen into the atmosphere and combining hydrogen with carbon dioxide to make glucose, the main energy source for living things.

b. Na+ will exit the cell, and the cell will depolarize
c. Na+ will enter the cell, and the cell will hyperpolarize
d. Na+ will exit the cell, and the cell will hyperpolarize

Answers

A neuron depolarizes when the Na+ channels open, and the ion flows into the cell. If you open an Na+ channel in a typical neuron, Na+ will enter the cell, and the cell will depolarize. Option A.

When does a neuron depolarize?

When the electrical stimulus is applied to the neuron or when a neurotransmitter joins its receptor, ion channels activate.

Ion channel openning produces depolarization by letting sodium get into the cell.

Depolarization, due to the increase of possitive charges, propagates to inactivated regions adjacent to the membrane opening more sodium channels.

Ions traffic will consist of the pass of sodium to the interior of the cell and potassium to the exterior.

K+ follows a concentration gradient,Na+ follows an electrochemical gradient.

The interchange results in an increase of positive charges in the interior of the cell. This depolarization activates an action potential that extends to the rest of the membrane.

So, when openning a Na+ channel in a typical neuron, Na+ will enter the cell, and the cell will depolarize. Option A is correct.
