Answer:

Letter B

Explanation:

Moulting or ecdysis is a process that occurs in arthropods and is characterized by changing the skeleton of these animals to ensure their growth. This process is essential because these invertebrates have an external skeleton, which makes continuous growth impossible and for this reason this animals need to change its skeleton and to produce another new one.

Despite being rigid, the animal gets its movement thanks to the joints. Because of this property, the phylum was named Arthropoda, which means “articulated feet”. The interesting thing is that you can see these periodic seedlings scattered in the environment, like and "bark".

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

The action potential propagates along the sarcolemma. as the action potential spreads down the t tubules of the triads, voltage-

Ganezh [65]

It permits calcium to leave the sarcoplasmic reticulum and enter the cytosol. During muscle contraction, the binding of acetylcholine initiates an excitatory impulse, which is transmitted to the deep of the muscle via T tubules. T tubules are the invaginations of cell membranes of muscle cells (sarcolemma). When the action potential travel down the t-tubules, they change shape and allow the calcium ions to enter into the sarcoplasm from the sarcoplasmic reticulum.

To code for the operating microscope, what verbiage are you looking for in the medical record?

(a)loupes were donned for magnification

(b)microdissection may be necessary

(c)due to the intricate dissection under magnification

(d)the operating microscope was steriley draped and brought into the surgical feild

<u>Answer</u>:

Option D: The operating microscope being sterilely draped and brought into the surgical field.

<u>Explanation:</u>

The loupe present is for the single vision magnifying glass, that can be frequently seen with the gold smith and with the watchmakers. The operating microscope are the binocular microscope through which small intricate parts can be observed during repairing of the watches etc. It is used in the surgery for observing the blood vessels as well as the nerves. This instrument can never be sterilized so after the use, it should be properly wrapped sterilely and kept inside the operation room.
