Physical activity may strengthen your bones and muscles, help you maintain a healthy weight, increase your ability to carry out daily tasks and improve your cognitive health.
Adults who spend less time sitting and engage in any level of moderate-to-vigorous exercise reap some health advantages. Physical activity has a greater influence on your health than very few other lifestyle decisions.
Physical activity has health advantages for everyone; age, ability, ethnicity, form, or size are irrelevant. Following a session of moderate-to-vigorous exercise, physical activity has some positive effects on brain health. Children aged 6 to 13 will experience better thinking or cognition and adults will have less transient anxiety.
As you age, staying physically active on a regular basis might help keep your thinking, learning, and judgment abilities sharp. Additionally, it can improve your quality of sleep and lower your risk of anxiety and sadness.

what are the three main polysaccharides? Provide a description of the structure and function for each.
The three main forms of polysaccharides, cellulose, starch, and glycogen, are also referred to as glycans and are all created by connecting glucose molecules in various ways.
What is meant by polysaccharides?The most prevalent kind of carbohydrates in food are polysaccharides, often understood as polycarbohydrates. They are long-chain polymeric carbohydrates made up of glycosidic connections that connect monosaccharide units. Using amylase enzymes as a catalyst, this carbohydrate can combine with water to create its constituent sugars. The three main forms of polysaccharides, cellulose, starch, and glycogen, are also referred to as glycans and are all created by connecting glucose molecules in various ways. One molecule, cellulose, is thought to contain 50% of the organic carbon in the planet.
The polysaccharide cellulose, an organic molecule with the formula n, is made up of a linear chain of several hundred to many thousands of D-glucose units that are covalently bonded. Green plants, numerous types of algae, and oomycetes all have basic cell walls that contain cellulose as an essential structural element.A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. Most green plants synthesize this polysaccharide as a form of energy storage.The stored form of glucose, known as glycogen, is composed of several linked glucose molecules. Your body's major source of energy is glucose (sugar). You get it from the macronutrient carbs found in some of the foods and beverages you consume.To learn more about polysaccharides refer to:

Through a published schedule and set of guidelines, the Centers for Disease Control and Prevention (CDC) and public health officials recommend that every child receive certain vaccinations by age 6. What are the benefits of this recommendation to public health officials, to the community and to other children?
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

Cell division: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.
What is the function of cell division?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.

Neuromuscular coordination is the ability of the central nervous system (CNS) to control the muscles to perform specific tasks unconsciously.
Neuromuscular coordination has two components: Intramuscular coordination and Inter muscular coordination. Both components are necessary for the efficient use of muscles. It is found between the terminal end of a motor nerve and a muscle.
Neuromuscular coordination is also referred to as "muscle memory".The number of muscle fibers varies between muscle groups. It is an important factor in long training.

lens that causes the light to
refract?
A. It is a medium that speeds up light.
B. It is a medium that does not change the light.
C. It is a medium that slows down light.
D. It is a medium that absorbs light.
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.

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.
