How does the atmosphere protect the earth

Biology
1 answer:
jek_recluse [69]3 years ago
5 0

Answer:

The atmosphere protects earth from the suns strong rays and keeps our oxygen on earth for us to breathe. Not to mention the moon would start taking all our water. If we somehow DID survive, we would not last very long, for the earth would over heat and with no plants, animals, or water, we would either die from starvation or from dehydration. If it weren't for the atmosphere our world would be burned to a crisp like Venus!

How is heart rate collected during the ymca 3-minute step test to evaluate the cardiorespiratory fitness level of an individual?
vredina [299]

It is measured over a 60-second count immediately following the test.

After completing the test, the individual sits while the fitness professional palpates the radial pulse (within 5 seconds of test completion) and measures the number of heartbeats over the ensuing 60 seconds.

<h3>What is cardiorespiratory fitness?</h3>

Cardiorespiratory fitness (CRF) refers to the ability of the cardiovascular and respiratory systems to oxygenate the mitochondria of skeletal muscle  for the energy production required during physical activity. CKD is an important indicator of adolescents' physical and mental health and academic performance.

Forms of exercise that rely on cardiorespiratory endurance include strenuous distance running, swimming, and cycling. This aspect of fitness  also affects your ability to perform low-intensity, sustained, full-body exercises, such as  walking, without feeling undue fatigue.

Walking briskly, climbing stairs, doing household chores. High levels of physical activity and cardiorespiratory fitness (referred to simply as “fitness” in this article) are associated with reduced all-cause and cardiovascular mortality. In addition, physical activity can reduce the incidence of chronic diseases such as hypertension, diabetes, stroke and cancer.

Edwin Hubble was an American astronomer who played a crucial role in collecting evidence to support the theory that the universe
Masja [62]

Answer:

C

Explanation:

These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.

Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.

We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.

I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
