Which process must occur for a muscle to be able to relax?
A. A nerve must initiate an action potential in the muscle fiber.
B. The amount of ATP in the neuromuscular junction must increase.
C. The concentration of calcium in the myofibril must decrease.
D. Myosin and actin must attach to each other.
Answer: C. The concentration of calcium in the myofibril must decrease.
I hope this helps.
Answer:
c
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.

A pH of 7, [H+]=[OH] below pH 7, which of these is greater_____. Bases have a pH that is ______ than 7
Answer:
below pH 7 H+ is greater because hydrogen ions are produced only by acids in an aqueous solution and acids have a pH below 7
bases have a pH that is greater than 7.
Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?
A
Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
B
С
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.
D
atoms determine the number of valence electrons determine the stability of the atom based on above
Enzymes are the bio-catalysts. Their presence can increase the rate of a reaction. Enzymes are most effective at a particular pH and temperature but can also function over a range of pH and temperature. Thus, correct option is A.
What are Enzymes?Enzymes are the biocatalysts which are responsible for increasing the rate of a chemical reaction. The enzymes increase the rate of a reaction by decreasing the activation energy which is required by the reactant molecules to collide and form products.
Enzymes are found to function over a range of pH, temperature, and solvents. Enzymes work over a range of different conditions. The value of pH and temperature at which enzymes show highest activity is called optimum condition. Below and above this point, enzymes function but the activity will be lesser than that in the optimum condition.
Therefore, A is the correct option. Enzymes are most effective at optimum condition of pH and temperature.

What happens during the light-dependent and light independent reactions of photosynthesis?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
The energy from sunshine is collected by chlorophyll and transformed into stored chemical energy through light-dependent processes. Chemical energy is used in light-independent processes.
The stroma is where photosynthesis' light-independent processes take occur. It includes enzymes that, in conjunction with ATP and NADPH, “fix” carbon from CO2 into molecules that may be utilised to make glucose. The stroma also stores the chloroplast's own genetic material (which is distinct from that of the cell).

which feature distinguishes protostomes from deuterostomes?
Answer:In Protostomes (“mouth first”), the mouth develops at the blastopore (Figure 3). In Deuterostomes (“mouth second”), the mouth develops at the other end of the gut (Figure 3) and the anus develops at the site of the blastopore. Protostomes include arthropods, mollusks, and annelids.
Explanation:
The question is in the image below:
Answer:
I think that the answer is true
How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!

How did dark matter affect the development of structures in the early universe?(1 point)
It cooled pockets of gas to form nebulae.
It became part of black holes.
It seeded the development of quasars.
It seeded the development of galaxies.
Answer:it seeded the development of galaxies
Explanation:
Dark matter affected the development of structures in the early universe as it seeded the development of galaxies.
Dark matter is simply refered to as a glue that bounds the Universe together. they are also dark matter halos are now stated to be the sites where galaxies were born. The universe as a whole ks made up of helium and hydrogen, dark matter was very essential in giving of the gravitational force needed in the gathering of elements together to form stars.Conclusively we can therefore say that Dark matter is the sit that holds the existence of galaxies.

describe why animals are eukaryotic organisms and why we say their cells are advanced and specialized
Answer:
The reason why they are eukaryotic is that:
- have nuclei
- organelle surrounded by a membrane called the nuclear envelope (where DNA is stored).
why they are advanced and specialized:
- They have power plants called mitochondria.
- these cells evolved into multicellular organisms.
- Eukaryotic cells carry out complex metabolic reactions that prokaryotes cannot.
Explanation:
Eukaryotic organisms are said to have an advanced cell because they contain membrane bound organelles.
Eukaryotic organismsEukaryotes are microorganisms that are made up of membrane bound organelles and whose nucleus is enclosed in a nuclear envelope.
Example of eukaryotes are:
animals,plants, fungi, andprotists.These organisms are said to be advanced and specialized because of the presence of membrane bound organelles which helps them to maintain a stable internal environment.

integral proteins are important to maintain the strength of the cell membrane. true of false?
Answer:
false
Explanation:
Integral proteins are one type of membrane protein. They are constantly associated with the membrane, carrying out many different functions but they do not maintain the strength of the cell membrane. The sentence is False.
-----------------------------------
Plasmatic membranes are composed of lipids and proteins.
Among the proteins, we can find integral proteins and peripheric proteins.
Integral proteins are permanently associated with the membrane.
They accomplish many different functions such as substances transport, cellular receptors, cellular adhesion, among others.
According to how they are incrusted in the lipidic bilayer, integral proteins might be,
Transmembrane proteins ⇒ span the entire membrane⇒ present in every membrane cells
Monotypic integral proteins ⇒ attached to only one of the lipidic layersIntegral proteins provide structure to the plasmatic membrane, but they do not maintain its strength.
