Answer:
The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that (Primer Section Key Terms O)
A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.
Explanation:
Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle´s contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase , increasing muscle´s force as well.
No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.
Answer:
Assimilation is the movement of digested food molecules into the cells of the body where they are used. For example: glucose is used in respiration to provide energy. amino acids are used to build new proteins.
Explanation:
Answer:
5732 years
Explanation:
Radioactive decay can be determined by using the equation:
where;
= number of decayed atoms at time (t)
= initial number of decayed atoms
= decay constant
So, if we equate the natural log of the above; we have:
where;
= 
= 
= 
t = 5732.01 years
t = 5732 years.
Hence, the fossil is 5732 years old.
