what does the model apply about the relationship between photosynthesis and cellular respiration
Photosynthesis makes the glucose that is used in cellular respiration in order to make energy molecules in the form of ATP.
What is the difference between photosynthesis and respiration?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.

Suggest why the quantity of water vapour in expired air is always high?
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.
Why does expired air contain more oxygen?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.

In some countries, human waste is used as a fertilizer. If produce is grown in this type of fertilizer, it is possible that it will be contaminated with the protozoan that causes amoebic dysentery. One method of removing the protist without ruining the food is to place the produce in a 5% salt solution. Explain how this would kill the protist. How could you return them to normal?
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.

explain between glucose and glycogen and the role of the liver maintaining the blood glucose
In response to the pancreatic hormones insulin and glucagon, the liver helps maintain blood glucose levels. Glucose enters the liver after a meal, and blood glucose levels rise. This excess glucose is handled by glycogenesis, which occurs when the liver converts glucose into glycogen for storage.
What is blood glucose?Glycemia is the concentration of glucose in the blood of humans or other animals. It is also known as blood sugar level, blood sugar concentration, or blood glucose level. A 70 kg person's blood contains approximately 4 grams of glucose, a simple sugar, at all times. A fasting blood sugar level of 99 mg/dL or less is considered normal, 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes. The main sugar found in your blood is blood sugar, also known as glucose. It is the primary source of energy in your body and is derived from the food you eat. Your blood transports glucose to all of your body's cells, where it is used for energy. Diabetes is a disorder in which your blood sugar stations stand too elevated.To learn more about glycogen, refer to:

The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.
What role does the liver have in maintaining blood glucose?By converting glycogen into glucose, a process understood as glycogenolysis, the liver produces sugar or glucose. By gathering amino acids, waste materials, and lipid byproducts, the liver can also produce the glucose or sugar that is required. Glucose 6-phosphatase catalyzes the buffering effect of liver glycogen to maintain blood glucose levels. Glycogenolysis in muscles converts glucose 6-phosphate into glycolysis without wasting any adenosine triphosphate (ATP), as this enzyme is exclusively found in the liver.By balancing the uptake and storage of glucose through glycogenesis with the release of glucose through glycogenolysis and gluconeogenesis, the liver plays a crucial part in this process. The numerous substrate cycles in the main metabolic pathways of the liver are crucial in controlling the generation of glucose.The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.

Answer: to ensures your baby's immune system gets the help it needs to protect your child long-term from preventable diseases. Not vaccinating your child on time can make someone else sick.
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.
What is vaccination?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
