The cardiovascular system delivers oxygen and glucose to the working muscles. It also takes carbon dioxide and other wastes away is the main function of the cardiovascular system during physical activity. Correct option is A.

The main function of the cardiovascular system during physical activity is to deliver oxygen and nutrients, such as glucose, to the working muscles to support their increased energy demands. As muscles work harder during exercise, they require more oxygen and glucose for energy production. The cardiovascular system, consisting of the heart, blood vessels, and blood, works to transport oxygen and glucose from the lungs and digestive system, respectively, to the muscles.

Simultaneously, the cardiovascular system is responsible for removing waste products, such as carbon dioxide and lactic acid, from the muscles. These waste products are generated as a result of increased energy production during exercise. The cardiovascular system carries these waste products away from the muscles and delivers them to the lungs (for carbon dioxide) and other elimination organs for excretion.

In summary, the cardiovascular system plays a crucial role in providing the necessary nutrients and oxygen to the working muscles during physical activity while removing waste products to maintain proper muscle function and overall performance.

Messenger RNA (mRNA) vaccinations include mRNA, a single-stranded RNA molecule which complements DNA. It is produced in the nucleus when RNA polymerase transcribes DNA to produce pre-mRNA. Prior to a COVID-19 pandemic, mRNA vaccines target infectious illnesses such as HIV-1, rabies, Zika, and influenza, as well as mRNA vaccines targeting several hematologic and solid organ cancers, were in clinical trials. Pfizer and BioNTech began developing an mRNA vaccine for SARS-CoV-2 shortly after the COVID-19 pandemic, as did Moderna, the latter in collaboration with the National Institute for Allergy and Infectious Diseases.
