I believe there are three correct answers from the choices listed above. The statements that describe an element are as follows:

<span>An element is a pure substance that cannot be broken down into a simpler form.
</span><span>All elements are listed on the periodic table of elements.
An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter.</span>

The endoplasmic reticulum (particularly the rough endoplasmic reticulum) has ribosomes attached to it, a type of organelle that synthesizes protein. It also itself folds proteins in sacs on its surface called cisternae.

The question, however, most likely is referring specifically to ribosomes, as these are the organelles primarily responsible for the production of proteins. The endoplasmic reticulum is mostly to assist the ribosomes and transport the proteins once they are properly folded.

What are the pros and cons of CRISPR-cas9
professor190 [17]

Answer:

It has incomparable advantages over other gene editing tools.

Explanation:

For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.

The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.

Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.

this the best i got, hope it helps :)
