What causes the striated appearance of skeletal muscle fibers quizlet

SAT
1 answer:
Airida [17]2 years ago
7 0

The Skeletal muscle tissue has a striated appearance due to repetitive bands of the proteins actin and myosin that run the length of myofibrils.

Dark A light and bands I bands repeat along myofibrils, and myofibril alignment causes the entire cell to seem striated or banded.

<h3>What is a striated appearance?</h3>

Striated muscle tissue is made up of repeated functional units known as sarcomeres.

Sarcomeres are evident as a series of bands along the muscle fibers, which is responsible for the striated appearance seen in microscopic photographs of this tissue.

What are the main rules of writing a will? check all that apply.
kykrilka [37]

Answer:

A) In most states, you must be eighteen or older.

B) The document must clearly state that it is your will.

E) A will must be written in sound judgement and mental capacity.

F) An executor must be named to oversee the distribution of the estate

Explanation:

The testament (from the Latin testario mentis, which means "testimony of the will") is the legal act by which a person disposes for after the death of the owner (which may be a family member or a person to whom he has esteemed) ) of all or part of their assets. It is not synonymous with making a dedication. Some authors maintain that it does not come from "testario mentis", but that its origins are found in the word "testis", for which reference is made to the witness; that is to say, the testament has no meaning as a material expression of will, but is an act in which this will is attested. The testament also admits non-patrimonial acts, such as the recognition of children.

Paradichlorobenzene, c6h4cl2 c 6 h 4 c l 2 , is a component of mothballs. A solution of 2. 00 g g in 22. 5 g g of cyclohexane bo
Nimfa-mama [501]

The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m

<h3>Understanding Molality of a Solution</h3>

Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)

Now;

Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol

Number of moles of C₆H₄Cl₂ = 0.0136 mol

Molality of solution = 0.0136/(22.5 * 10⁻³ kg)

Molality of solution = 0.6 m

Now, to find kb for cyclohexane, we will use the formula;

T_b(solution) - T_b(solvent) = kb × molality of solution

Thus;

82.39 - 70 = kb * 0.6

kb = (82.39 - 70)/0.6

kb = 2.82 °C/m
