Why is the sarcoplasmic reticulum. How does it aid in the stimulation of muscle contraction?

Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.
</span>Nervous stimulation causes a depolarization<span> of the muscle membrane (sarcolemma) </span>that<span> triggers </span>the discharge<span> of </span>calcium<span> ions from the sarcoplasmic reticulum.</span>

Answer:

It bathes the sarcomere in calcium.

Activated when muscle cells are stimulated.

It stores large amounts of calcium.

Are gender traits completely a result of societal expectations?
musickatia [10]

\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star

No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.

But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.

This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development

trapecia [35]

Answer:

D. MicroRNA-1/206 targets c-Met mRNA for destruction via RISC.

Explanation:

microRNA's are non-coding RNA's, that is, they are not translated to proteins. MicroRNA-1/206 leads to gene silencing by 'tagging' the c-Met mRNA for cleavage by RISC proteins.

RISC: RNA-induced silencing complex is a ribonucleoprotein complex that leads to the incorporation of a single strand of micro RNA (or siRNA) that will bind to the targeted mRNA. The microRNA or siRNA strand will tag the targeted RNA for cleavage by proteins from the ribonucleoprotein. No translation will occur.

The relationship between population growth and resources can be described as
Lina20 [59]

A

The relationship between population growth and resources is inverse; as one goes up the other goes down.

Explanation:

An inverse relationship is one where when one variable is affected positively, the other is negatively impacted, and vice versa. In other terms, when one variable increases the other decreases.

When population growth increases, the strain on the resources increases, due to increased competition, and hence the resources decrease. This is why ideally apopulation cannot grow indefinitely because resources are always limited. The population growth will start to levels off as it reaches carrying capacity. When the resources become depleted the population growth plummets.
