Answer: B. It could disrupt the rate of respiration

In a way, a disorder in the endocrine system may affect the respiratory system of a person. This is due to the fact that an endocrine condition may directly affect the respiration of a patient.

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has
Dima020 [189]

Answer:

The unearthed Humerous bones don't belong to the species A.

Explanation:

Hello!

You are studying the Humerus bones species A, who is known to have a mean ratio of 8,5. This value corresponds to the population mean of the length-to-with ratio of bones of species A, symbolized as μ.

The hypothesis you want to study is "The Humorous bones unearthed belong to the species A" if you assume this to be true, then the mean of the length-to-with ratio should be equal to the known population mean of the length-to-with ratio.

Symbolized:

H₀: μ = 8,5

H₁: μ ≠ 8,5

Significance level: α: 0,05

You are asked to use a Z-test, since you don't know the value of the population variance, but have the sample values, the sample size is big enough (more than n=30). Assuming that the sample values are independent, the statistic test of choice is the approximation:

Z= \frac{x_bar-μ}{S\sqrt[]{n} }≅N(0;1)

The critical region, in this case, it's a two-tailed test (remember the type is determined by the null hypothesis) so you'll have two critical values.

Left value [/tex]Z_{\alpha/2} = Z_{0,025} = -1,96

Right value Z_{1-\alpha/2} = Z_{0,975} = 1,96So you'll reject the null hyphotesis if the calculated [tex]Z_{obs} value is ≤-1,96 or ≥1,96 and you'll support it if -1,96<Z_{obs}<1,96

Now we calculate the statistic by replacing the formula with the data:

x_bar = 9,26

S = 1,20

n = 41

Z_{obs}= \frac{x_bar-μ}{S\sqrt[]{n} }

Z_{obs}= \frac{9,26-8,5}{1,20\sqrt[]{41} }

Z_{obs}= 4,0553

Since the calculated value falls in the rejection region, this means, you have statistically significant results. In other words you can reject the null hipothesis (H₀: μ = 8,5) and asume that the unearthed Humerous bones don't belong to the species A.

I hope you have a SUPER day!

Neurotransmitters that cause skeletal muscle contraction are norm
myrzilka [38]

Answer: B) motor neuron ending

Explanation:

Neurotransmitters caused the contraction of the skeletal muscle as, the skeletal tissue muscles are composed of the cells known as muscle fibers. When the signal from the nervous system are reached to the junction of the neuro muscle then, a chemical notification are indicated by the motor neuron ending.

Explain how anaerobic respiration results in muscle fatigue​
Doss [256]

Answer:

Explanation:

However, ATP production by anaerobic respiration may still support some further muscle contraction. Ultimately, the accumulation of lactic acid from anaerobic respiration and the depletion of resources (ATP, oxygen, and glycogen) lead to muscle fatigue, and muscle contraction stops.
