what kind of graph is this? ?
a. bar graph
b. exponential graph
c. logistic growth graph
d. line graph
explain your answer

Line graph, or dot graph.

Explanation:

it has a line that shows the approximate system of equations.

It's D

Explanation:

a. is a bar grabh that goes into a lot of bars showing a time and a number of growth. it like putting some actual bars next to eachother. Therefore it isn't a

b. isn't it either as, and exponetial graph would go as a bow on the X and Y system. and only grow.

C it isn't either as youre not using f(x)=ax+b

so D it is.

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
