Which of the following is required of a new drug?
A. It must bind to a virus.
B. It must be in liquid form.
C. It must be easy to swallow.
D. It must help cure a disease.
Answers
Answer:
D. It must help cure a disease
Hope that helps!
Explanation:
It must help cure a disease. For a new drug to be approved by regulatory agencies such as the FDA (Food and Drug Administration), it must undergo rigorous testing to demonstrate its safety and efficacy in treating a specific disease or condition. Hence option D is correct.
What is a drug?A drug is a substance that has a physiological effect when ingested or otherwise introduced into the body. Drugs can be used for a variety of purposes, including treating or preventing disease, managing symptoms, altering mood or consciousness, or enhancing physical or cognitive performance.
The drug must also be shown to have a favorable benefit-to-risk profile, meaning that its potential benefits outweigh any potential risks or side effects. The drug's mechanism of action, or how it works in the body, is also an important consideration in the approval process.
While a drug may bind to a virus, be in liquid form, or be easy to swallow, these characteristics alone do not make a drug effective in treating a disease.
The ultimate goal of drug development is to find treatments that can help cure, prevent, or manage illnesses, so efficacy and safety are the most important factors in determining whether a new drug will be approved for use.
Hence option D is correct.

Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.
Answers
Answer:
Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.
Explanation:
The table and data was not attached to the question.
When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)
Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
That is mass of reactant = mass of product = 100g + 10g = 110g
Sarah got 105g as product because a gas of mass 5g was released during the reaction.
Sarah found the mass of the resulting
mixture without including the mass of the released gas.
A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.
When this is done, the law of conservation of mass would be proven.

How would permeability change if types of channels in a neuron change?
Answers
Answer:
Explanation:
How the resting membrane potential is established in a neuron. ... Ions move down their gradients via channels, leading to a separation of charge that ... through brief, controlled changes in the permeability of their cell membrane to particular ... If you did this, you would measure an electrical potential difference, or voltage, ...
Membrane permeability is affected by temperature, the type of solute present, and the degree of cell hydration. Increasing the temperature makes the membrane more unstable and very fluid. Lowering the temperature slows the speed of the membrane.
Does the permeability change during the action potential?Action potentials, the main electrical signal produced by nerve cells, reflect changes in membrane permeability to specific ions.
The important point is that increasing Na + permeability causes more depolarization, resulting in the opening of more Na + channels and further depolarization of the membrane potential.
Membrane permeability to water and solute has been shown to depend on temperature, the osmotic pressure of the medium, the type of solute present, the degree of cell hydration, and the presence or absence of ice.

A. (birth rate + immigration) - (death rate + emigration) best defines the population growth.
What is population growth?Population expansion is the term used to describe the increase in human population. Most of human history was marked by a rather stable population. However, innovation and industrialization made energy, food, water, and medical care more reliable and accessible.
The human population has grown dramatically over the last century. It has mostly accomplished this by producing copious amounts of food and figuring out how to deal with sickness. There may have been only a million people on the planet when mankind first developed agriculture ten thousand years ago.
Despite the fact that every demographic pyramid is different, most fall into one of three categories: expansive (young and rising), constrictive (elderly and shrinking), or stagnant (little or no population growth).

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.
Answers
Answer:
The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.
The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.
The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.
Explanation:
The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.
In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

10. Define immunity, and distinguish between active and passive immunity. this should be 150 words. I will mark as BRIANILIST. thank you.
Answers
Answer:
Immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or another unwanted biological invasion, while having adequate tolerance to avoid allergy and autoimmune diseases. Each part of the immune system has a unique function. Also, the immune system is responsible for down-regulating immune responses against external harmless triggers such as food, or against the bodies' tissue. Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. And passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through the placenta. Passive immunity refers to the transfer of antibodies from one individual to another.

Answers
Answer: By looking at all the age population pyramids, this would be my best guess. Every territory is different with various populations, however, to the best of my knowledge, it would be the expansive pyramid.
Explanation: Expansive population pyramids are used to describe populations that are young and growing. They are often characterized by their typical ‘pyramid’ shape, which has a broad base and narrow top. Expansive population pyramids show a larger percentage of the population in the younger age cohorts, usually with each age cohort smaller in size than the one below it. These types of populations are typically representative of developing nations, whose populations often have high fertility rates and lower than average life expectancies.
