Nadya [2.5K]

The answer to this question would be: risk taking

In this case, the nurse <span>finds that one of the prescribed drugs is redundant and notifies the primary healthcare provider. To recognize the drug as redundant the nurse should have read some source about that drug. The nurse notifies the primary health care in hope to changes the medication. It was a risk-taking attitude since that means the nurse willing to take the risk to implement the knowledge.</span>

Drag the pink labels onto the pink targets to identify the two main phases of the cell cycle. Then drag the blue labels onto the

zavuch27 [327]

Answer:

There is no diagram provided so I will just explain the mitotic cell cycle.

Here’s a quick basic arrangement in chronological order interphase, mitosis, and finally cytokinesis.

So first you start with interphase which consist of three phases G1 phase, S phase, G2 phase. Cellular growth occurs in G1 phase of interphase this is followed by S phase which is simply when DNA replication occurs. Final this is followed by G2 phase or further growth in preparation for mitosis and/or meiosis.

I am only going to explain mitosis but just so I don’t confuse you meiosis can also follow interphase. So mitosis consist of four phases. Prophase, metaphase, anaphase, and telophase.

Prophase: in this phase the nuclear membrane would dissipate and the chromosomes would condense.

Metaphase: then in metaphase the chromosomes would align in the center of the cell and spindle fibers or microtubules would began growth from the centrioles.

Anaphase: by the start of this phase spindle fibers would have attached themselves to the chromosomes kinetochores. In this phase the chromatids would separate and that’s really it as you can tell this is the shortest phase in mitosis.

Telophase: finally the chromosomes would be brought to the polar opposite ends of the cell and the nuclear membrane would reform. Also the chromosomes condensed chromosomes would unravel eventually they would be invisible.

Finally the cell would enter cytokinesis were it would split at the cleavage furrow which would have started in anaphase of telophase, all a cleavage furrow is, is microfilaments “pinching the cell” which is just them pulling on either side of the center of the cell.

Each atom of the element argon has 18 electrons. How many chemical bonds is one atom of argon likely to make with atoms of other

densk [106]

It won't. Argon is an element found in the Group 8A also called as the noble gases. They are called as such because they do not react with other elements because their electronic configuration is very stable. This is because they already obey the Octet rule, which has to do with eight electrons occupying around the element. So, it is very rare to have reaction involving any of the noble gases.
