Well because we can use those elements for are own personal use like combining them to make better things like iron is in lots of things. Without knowing alot about the elements we wouldnt know how to use them

It is very useful for humans to know a great deal about the property of certain elements. This is because knowing such information can allow us to better employ the elements to benefit our lives. This is why the role of scientists in our society is so vital. Scientists not only discover the properties of the elements, but they also come up with ways in which we can use them safely, sustainably and efficiently.

What is the ratio strength of 100 ml containing a 1:50 povidone iodine solution diluted to 1000 ml? (answer must be numeric; no

guapka [62]

We are given that:

100 mL total solution with 1:50 povidone iodine solution

This means that there is 1 mL of povidone iodine solution per 50 mL of total solution. Since we are given a total of 100 mL solution, therefore we have an initial amount of:

pure povidone iodine solution = 2 mL

This amount of pure povidone iodine solution is added or diluted (most perhaps with water) to make a total of 1000 mL total solution, therefore the new ratio is:

2:1000 povidone iodine solution

By dividing both sides by 2, this simplifies to

1:500 povidone iodine solution

Answer:

1:500

How many moles of Ca are in 7.2x10^25 molecules of Ca<br> (show work)

Gre4nikov [31]

Answer:

<h2>119.60 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{7.2 \times {10}^{25} }{6.02 \times {10}^{23} } \\ =119.60132...$

We have the final answer as

<h3>119.60 moles</h3>

Identify the role of all molecular constituents present in a functional polyribosome. Drag the terms on the left to the appropri

nikitadnepr [17]

A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that form a polypeptide chain during active translation. Since multiple ribosomes can translate mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.

<h3>Role of all molecular constituents present in a functional polyribosome ;</h3>

1. mRNA: contains the codon

2. tRNA : contains the anticodon for the mRNA

3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA

4. Amino acids:

5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence

7. Elongation Factors: bring charged tRNA's to the A site of the ribosome

8. GTP: provides energy

Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that overlapping sequences will be translated.
