Explain the events of the sliding filament theory of skeletal muscle contraction beginning with immediately after the release of Ca++ from the sarcoplasmic reticulum and ending at the end of one cross bridge cycle.
Answer:
According to the sliding filament theory, the myosin (thick) filaments of muscle fibers slide past the actin (thin) filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.
Explanation:
The sarcoplasmic reticulum stimulated to release calcium ions.
Calcium ions bind to troponin. ...
Cross bridges (on myosin) pull on actin (power stroke) ...
Cross bridge detaches from binding sites on actin.
Muscle fiber lengthens & relaxes.
Calcium ions actively pumped back into sarcoplasmic reticul

Do you believe that most of the resources we have on Earth are
limited or unlimited?
There are limits to everything; at this rate, we'll run out of all our
resources.
Resources may not all be limited, but shortages will severely
disrupt our lives in the future.
Resources such as fossil fuels may be limited, but we'll
eventually switch to renewable ones.
Resources are essentially unlimited; we'll use technology to
overcome any shortages.

8 The luteal phase spans from
days 1-5
days 6-14
days 15-28
none of the above
Answer:
The correct answer is - None of the above.
Explanation:
The luteal phase is the stage of the menstrual cycle in which the lining of the uterus or uterine walls normally gets thicker for pregnancy. this phase begins after ovulation and ends just before the periods start. If pregnancy does not take place wall starts to shed.
A normal luteal phase spans from 12 to 14 days, however, it can last anywhere between 11 to 17 days. Less than 10 consider as a shorter luteal phase and more than 17 is a longer luteal phase.
What methods allow scientists to tell the age of rocks and what does this tell us about the Earth’s history
Answer:
One method that allows scientists to tell the age of the rocks are radiometric dating; this method is done by finding the natural radioactive decay of elements like carbon; for EX. rocks found deeper in the core of the earth will have less carbon than rocks found shallower in the earths core.
What this method can tell us about the history of earth is that through the collection of the levels of carbon and other properties that were in the air from older rocks, we can tell if an event occured during the earths history that configured those properties in the rock.
Explanation:
are all experiments designed the same way?
Answer:
Design of Experiments (DOE) is also referred to as Designed Experiments or Experimental Design - all of the terms have the same meaning. Experimental design can be used at the point of greatest leverage to reduce design costs by speeding up the design process, reducing late engineering design changes, and reducing product material and labor complexity.

Answer:
3 purple fur : 1 white fur
Explanation:
since purple fur (H) is dominant, it will show up if it's there. 3 on the boxes have H in them so 3/4 of the offspring will have purple fur and 1/4 will have white fur. hope this helps

Potential Energy on the way up the rollercoaster
Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

Explanation:
Amylase is an enzyme that digests starch.
A student investigated the effect of pH on the activity of amylase.
This is the method used.
1.
Mix amylase solution and starch suspension in a boiling tube.
2.
Put the boiling tube into a water bath at 25°C.
Remove a drop of the mixture every 30 seconds and test it for the presence of
starch.
3.
4.
Repeat the investigation at different pH values.
