For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.

There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.

Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.

With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.

The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.

sattari [20]

<em>Full Question:</em>

<em>Which tissue is correctly paired with its primary cell type?</em>

<em>bone: fibrocyte</em>

<em>bone: osteoblast</em>

<em>connective tissue proper: chondroblast</em>

<em>cartilage: fibroblast</em>

Explanation:

<em> </em><u><em>bone: osteoblast</em></u>

<u><em></em></u>

<u><em></em></u>

Osteoids comprise, significant sections of the entire bone matrix, and  this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.

Osteoblasts are highly specialized cells within bone which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification (fortification with allium) of osteoid during the formation of mature bone matrix.

Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%

Probability is the greater or lesser possibility of a certain event occurring.

In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.

Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

P(A)=\frac{number of favorable cases}{total number of possible cases}

In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:

total number of possible cases= 48 + 30 + 67= 145

The number of favorable cases for a moth to be brown is: 48

Then the probability that a moth is brown is calculated as:

P(A)=\frac{48}{145}= 0.33= 33%

On the other side, the number of favorable cases for a moth to be yellow is: 30

Then the probability that a moth is yellow is calculated as:

P(A)=\frac{30}{145}= 0.21= 21%

In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
