What likely happens to the heart rate as the cardiac muscle gets stronger? Explain your answer

1 answer:

8 0

The heart rate will likely decrease. As the cardiac muscle, or heart, gets stronger, it takes less effort to pump more blood. As a result, the heart will probably beat less, decreasing the heart rate. This is why athletes often have lower heart rates than the average person.

The function of a cell depends primarily on its ?

Schach [20]

Organelles which are very important in giving nutrients. During cellular respiration, the food molecules such as glucose, are oxidized to carbon dioxide (CO2) and water (H2O) and trapped in ATP (Adenosine triphosphate) form for further us of cell’s activities. ATP’s are formed at mitochondria – the cell’s powerhouse. This type of organelle takes and breaks nutrients absorbed by the cell and creates energy afterward. The energy from ATP is then used by the body in kinetic activities like running & walking or involuntary activities like breathing, blood circulation, stimulus-responding, etc.

The mathematical symbol for period is O A. A O B. v OC. T O D. f

Advocard [28]

Answer: C. T

Explanation:

Period is a unit of time; and in the context of waves or oscillations it is defined as "the time elapsed between two equivalent points on the wave or oscillation".

It is important to note Period (denoted by $T$ ) is one of the most important factors (along with the amplitude, frequency and velocity) to describe and characterize a wave.

In addition, Period has an inverse relation with the frequency $f$ , this means that if we are given the frequency of a wave, we can inmediatly know its Period.
