Answer:
100 to 140 heart beats per minute
Explanation:
Heart rate basically refers to the speed of the heartbeat which is most times measured by the number of times the heart of a human being contracts in a minute. It can always vary depending greatly on the physical needs of our body and the need to take in oxygen and exhale carbon(iv)oxide.
In the case of Rosa who's only 20 years old and intends exercising at moderate intensity, the advisable or normal heart rate of of young adults of her age who has probably not developed a medical condition of the heart should be anything from 100 to 140 heart beats per minute, that is since she intends to train or exercise at moderate intensity.
The most commons forms of colorblindness are genetic conditions, passed along the x-chromosome. People with an x-chromosome and a y-chromosome only need their one x to be defective to catch it. People with two x-chromosomes need both to be defective.
Most women have two x-chromosomes (XX), and most men have an x-chromosome and a y-chromosome (XY). That's why colorblindness is much more common in men than in women.
Explanation:
a wavelength is calculated by determining the distance between corresponding points on consecutive waves. Normally this is done by measuring from peak to peak or from trough to trough. When it comes to light, you can only see wavelengths of 400 to 700 billionths of a meter.
