How do people get sick?

Health
1 answer:
ziro4ka [17]3 years ago
8 0

Answer:

Viruses spread through tiny droplets in the air that are released when a sick person sneezes, coughs, or blows their nose. You can get sick if you touch your nose, eyes, or mouth after you have touched something contaminated by the virus, such as a toy, countertop, or doorknob.

Explanation:

A cold virus enters your body through your mouth, eyes or nose. The virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. It also spreads by hand-to-hand contact with someone who has a cold or by sharing contaminated objects, such as eating utensils, towels, toys or telephones.

You should be as general as possible when setting fitness goals, so as to allow improvement in all areas.
kirill [66]

The given statement is False.

You should not be as general as possible when setting fitness goals, so as to allow improvements in all areas.

Explanation:

Workout consists of two main aspects of exercises:

  1. Cardiovascular Exercises
  2. Strength Training

Cardiovascular exercises are done to increase the heart rate to the point where your muscles start to respond. After the cardiovascular part of the exercise, a person must focus on strength training. Strength Training allows a person to focus on specific areas of the body to reduce them or tone them.

For example, if there is a woman who gained fat on her legs but not on other parts of the body, should focus on strengthening and toning the legs. She should do 'Leg specific Exercises' in her workout after the cardiovascular session.

So while working out, doing general workout will not help you tone your body or give you fitness, rather you should focus primarily on the specific areas to get them fit.

Why do turtles breath out of their butts
luda_lava [24]

Answer: Limited room and no ribcage

Pls give me brainliest i had to research

Explanation: The possible answer to the question lies in the turtle's shell. The shell, which evolved from ribs and vertebrae that flattened out and fused together, does more than keep the turtle safe from bites. When a turtle hibernates, it buries itself in cold water for up to five months. To survive, it has to change a lot of things about the way its body works. Some processes, such as fat burning, go anaerobic - or without oxygen - in a hibernating turtle. Anaerobic processes result in the build up of lactic acid, and anyone who has seen Aliens knows that too much acid isn't good for a body. The turtle's shell can not only store some lactic acid, but release bicarbonates (baking soda to the acid's vinegar) into the turtle's body. It's not just armor plating, it's a chemistry set.

It is, however, a fairly restrictive chemistry set. Without ribs that expand and contract, the turtle has no use for the lung and muscle set-up that most mammals have. Instead it has muscles that pull the body outwards, towards the openings of the shell, to allow it to inhale, and more muscles to squish the turtle's guts against its lungs to make it exhale. The combination makes for a lot of work, which is especially costly if every time you use a muscle your body's acid levels go up and oxygen levels go down.

Compare this to the relatively cheap butt breathing. Sacs next to the cloaca, called bursa, easily expand. The walls of these sacs are lined with blood vessels. Oxygen diffuses through the blood vessels, and the sacs are squeezed out. The entire procedure uses little energy for a turtle that doesn't have a lot to spare. Dignity has to play second-fiddle to survival sometimes.
