Explanation: hope this helps

The benefits of the recommended vaccination schedule include improved public health, reduced disease transmission, protection for vulnerable populations, and prevention of outbreaks.

Vaccination, also known as immunization, is a medical process that involves the administration of a vaccine to stimulate the immune system and provide protection against specific infectious diseases. Vaccines are composed of weakened or killed pathogens, parts of pathogens, or harmless components that resemble pathogens. When a vaccine is introduced into the body, it triggers an immune response, stimulating the production of antibodies and the activation of immune cells.

The primary goal of vaccination is to prevent diseases and their complications. By receiving vaccines, individuals develop immunity to specific pathogens, making them less susceptible to infection. Vaccination not only protects the vaccinated individual but also contributes to public health by reducing the spread of infectious diseases within communities. This concept, known as herd immunity, occurs when a significant portion of the population is immune, preventing the sustained transmission of a pathogen and safeguarding those who cannot receive vaccines due to medical reasons or being too young.

Overall, vaccination has been one of the most successful and cost-effective public health interventions, saving countless lives and significantly reducing the burden of infectious diseases worldwide

The plant produce contaminated with the protozoan that causes amoebic dysentery when placed in 5% salt solution will kill the contaminants due to osmotic difference. The produce then can be brought back to normal by placing in pure water.

Amoebic dysentery is the disease caused by the microorganism called Entamoeba histolytica. The source of infection is human fecal matter. The symptoms of the disease includes abdominal cramps and diarrhea.

Osmotic difference is the difference of solute particles between two substances. When the protozoan cells are placed in salt solution, the salt solution has more solute particles that causes the secretion of water to the outside of protozoan cell, therefore causing its death by dehydration.

Two questions may include how pollutants may affect global warming or why chlorofluorocarbons hamper the ozone layer, which can be investigated by raising the hypotheses 'pollutants can drastically affect global temperature' or 'chlorofluorocarbons effectively alter the ozone layer', respectively.

An investigational hypothesis can be defined as a plausible explanation about the observation of phenomena that occur in the real world which must be tested by experimentational procedures in order to confirm or reject them.

During the scientific method, we raise questions that may be answered by confirming hypotheses, a process that leads to collecting empirical evidence in favor of such ideas.

Therefore, we can conclude that hypotheses such as for example if pollutants may affect global warming by acting as greenhouse gases can be solved by using the scientific method, which involves making experiments to confirm or reject the hypothesis.

Answer:   The correct answer is B. It is a medium that does not change the light.

Explanation:  The concave lense affects the phase velocity, but not the speed of light. A lens's shape determines the images it forms. When parallel rays of light enter a concave lens, the light waves refract outward or spread out. The light rays refract twice: first when entering the lens and second when leaving the lens. Only the light rays passing through the center of the lens remain straight.

A cell expands, makes additional organelles, and copies its DNA during the interphase.

Cell division is the splitting of a mother cell into two or more daughter cells. Cell division typically takes place as part of a lengthier cell cycle.

The two separate cell division processes are meiosis and mitosis. The process of making new cells for the body, known as mitosis, is usually meant when the term "cell division" is used. Meiosis, a cell division process, is what creates egg and sperm cells. Mitosis is an essential biological mechanism.

The process of cell division is how new cells are created for the body's needs of growth, repair, and replacement. Both the nuclear material and the cytoplasm are divided during this process. All somatic (or "somatic") cells in the body—aside from the gametes, which generate eggs and sperm—reproduce through a process called mitosis.

Photosynthesis makes the glucose that is used in cellular respiration in order to make energy molecules in the form of ATP.

We know that photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as a food product which is used by plants and oxygen as a by-product. The process of cellular respiration converts oxygen along with glucose into the water and into carbon dioxide.  Actually, water and glucose are the by-products, and ATP (adenosine triphosphate)  is the energy that is transformed from the process.

The energy released by photosynthesis is stored during the process of cellular respiration. During photosynthesis, the food is broken down during the process of cellular respiration.

So we can conclude that photosynthesis removes carbon dioxide from the atmosphere while cellular respiration again brings carbon dioxide.

According to the principle of equilibrium, when a constraint is applied in a reaction system in equilibrium, the equilibrium position shifts to annul the change.

Answer:

The answer is TRUE

Not all of the oxygen in the air is taken up by the lungs, and that the gases released when someone breathes out are heated to body temperature and saturated with water vapour. This results in the expired air having a larger water vapour content.

All of the oxygen in the air we breathe does not enter our lungs during the breathing process. The amount that is absorbed is little. Therefore, some oxygen is present in expired or exhaled air.

Since we don't consume nitrogen, the percentage of nitrogen remains close to 78%, but the significant difference is the rise in carbon dioxide. More or less 4% of the carbon dioxide and a larger percentage of water vapour than breathed air are found in exhaled air.

Water vapour makes up 0.02 to 0.04% of the air we breathe. Water vapour makes about 5.0 to 6.3% of exhaled air.
