Answer:

D) stereomicroscope (dissecting scope)

Explanation:

A <em>stereomicroscope</em> is a microscope that has low magnification and is often used to view the surface of the specimen to b observed and carry out works such as microsurgery and dissection where you don't need much greater magnification but a greater field view.

Therefore, when wants to the legs of an insect up close, the stereo microscope is the best choice as it allows to fit the insect leg in the view and also provide enough magnification.

In quiet breathing (A) inspiration is passive and expiration involves muscular contractions. (B) inspiration and expiration invo
Zolol [24]

Answer:

In quiet breathing inspiration involves muscular contractions and expiration is passive.

Explanation:

Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.

During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.

During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.

Are tyere any mammalian cells that would be a good source for dividing cells?
Artemon [7]

Answer:

Explanation:

This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.

There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.
