Utah has a large wetland connected to the Great Salt Lake. There are a wide variety of animals and plants that can survive in these wetlands. Looking at this energy pyramid, what would happen to the population of primary consumers if 90% of the the secondary
consumers died off due to a disease?
A)
the population would remain unchanged
B)
the population would grow due to being fewer predators
the population would decrease because of more predators
D)
the population would move to another habitat due to lack of food and
resources

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .

thats not a question

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.
