Answer:

D) Non-specific immunity

Explanation:

The mucosa, also known as the tunic or mucous membrane, consists of a lining epithelium associated with a connective tissue called lamina propria. It is responsible for the internal lining of moist body cavities that maintain contact with the external environment such as the mouth, intestine, bladder, respiratory tract and urogenital tract. Because they are subject to microbial invasions, the mucous membranes in these regions present as non-specific immunity and have lymphocyte accumulations in the form of lymph nodes associated with diffuse lymphatic tissue. In some regions, such as the ileum, the lymphatic tissue is organized into well-structured organs called Meyer's tonsils and plaques.

Label the following activities as either aerobic fitness, anaerobic fitness, muscular strength, muscular endurance, or flexibili
vlada-n [284]

Answer:

           

Explanation:

Soccer -- aerobic

Wall sits -- anaerobic

Max lift bench press -- strength

Jogging -- aerobic

Sprinting -- anaerobic

Stretching -- flexibility

Planks -- both strength and endurance

Basketball -- aerobic

Squats -- anaerobic

Speed walking -- aerobic

Sit-ups -- anaerobic

Yoga -- flexibility

Swimming -- aerobic

Aerobic fitness -- it is an ability for our bodies to transport and use the oxygen, in order to produce the energy we need for our muscles. During aerobic fitness, our heart rate and breathing increase for some period of time.

Anaerobic fitness -- oxygen is not used. Compared to the aerobic fitness, it is more quick, more energy is used, and the maximum effort is performed, and it lasts shorter than aerobic fitness.

Flexibility  -- it includes stretching, yoga, Tai-Chi. It is good because it lengthens our muscles. It increases physical and mental relaxation, it prevents our bodies from injuries, reduces soreness.

Muscular strength -- it's occurring in a short period of time and the maximum of our strength is used. By definition, it is the amount of force a single muscle can produce with a single MAXIMAL effort.

Muscular endurance --  the word says it itself -- how much we can endure.

Compared to the strength, which is manifested in a short amount of time, but used to its maximum, in this type of exercise we are more focused on the enduring. It is muscle's ability to endure repeated action against a resistance for a certain amount of time.

Answer;

The BEST weight to use for weight training in order to increase strength is one that is challenging but still allows for proper form.

Explanation;

Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles.

Strength training uses resistance, like free weights, weight machines, resistance bands, or a person's own weight, to build muscles and strength.

Besides building stronger muscles, strength training can:

  • improve overall fitness
  • increase lean body mass (more muscle, less fat)
  • burn more calories
  • make bones stronger
  • improve mental health
