Answer:
Seth is 18 years old, weighs 250 pounds, and is 72 inches tall. Use the formula and chart below to evaluate his weight, and then answer the question.
BMI = Weight (in pounds) ÷ [Height (in inches)]² x 703
BMI categories, general:
Underweight: less than 18.5
Normal weight: 18.5-24.9
Overweight: 25-29.9
Obese: 30 or greater
What does his BMI indicate about Seth's health?
A. He has a slight risk of weight-related diseases.
B. He is at risk of malnutrition.
C. He has a high risk of diabetes and kidney disease.
Answer:
B. Ashchronous recruitment
Explanation:
Asynchronous muscles are muscles that Don't have one-to-one relationship between electrical stimulation and mechanical contraction. Such muscles can be found in About 75% of flying insects and they have convergently evolved 7-10 times.
The synchronous muscles which is their counterparts contracts once per neural signal, but mechanical oscillations trigger force production in asynchronous muscles.
Hence the rate of mechanical contraction is an order of magnitude greater than electrical signals.
Although they achieve greater force output and higher efficiency at high frequencies, they have limited applications because of their dependence on mechanical strength.
The nervous system recruits the Ashchronous muscle to avoid muscle fatigue during submaximal contraction.
Answer:
Homeostasis, in a definitive way, is the maintaining of an animals internal and external enviorments in order to maintain proper and normal functioning.
Homeostasis is important to animals because it keeps their body in a steady state where they can continue to thrive and live.
When an animal can't maintain Homeostasis, it's bodily functions will begin to fail due to it's inability to maintain it's normal functioning in the present enviorment. Without Homeostasis, the body will become unstable and weak, leading shortly to death..
