A student decided to investigate the relation of height to resting heart rate. The student determined the resting heart rate of

frez [133]

Air temperature: When temperatures (and the humidity) soar, the heart pumps a little more blood, so your pulse rate may increase, but usually no more than five to 10 beats a minute.Body position: Resting, sitting or standing, your pulse is usually the same. Sometimes as you stand for the first 15 to 20 seconds, your pulse may go up a little bit, but after a couple of minutes it should settle down. Emotions: If you’re stressed, anxious or “extraordinarily happy or sad” your emotions can raise your pulse. Body size: Body size usually doesn’t change pulse. If you’re very obese, you might see a higher resting pulse than normal, but usually not more than 100. Medication use: Meds that block your adrenaline (beta blockers) tend to slow your pulse, while too much thyroid medication or too high of a dosage will raise it.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

hope it helps

Is Gause’s Principle accurate? Explain why or why not.

Novosadov [1.4K]

Gause's Competitive Exclusion Principle

The 'competitive exclusion principle' (CEP) states that two species with identical niches cannot coexist indefinitely. ... Gause helped propel ecology by his approach of experimentally testing mathematical models, and his unifying the concept of the niche with resource competition.

Megan observes four cells under a microscope and makes sketches of them as shown. Identify whether the cells are prokaryotic or

posledela

I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.

The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.

The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.

The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).
