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.
Oceanography bc they study on the ocean and whats going on
An enzyme is a biological molecule that acts as a catalyst in many reactions. They speed up chemical reactions especially the reactions inside living organisms. An enzyme is made up of amino acids. They are known to be very efficient catalysts. Hope this answers the question!
<h2>Competitive exclusion principle.</h2>
Explanation:
The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.
All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.
Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.
<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
Thirty-five percent of the trees cut down are used to make paper. That means sixty-five percent of the trees cut down are used for something other than paper. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
