What is the best way to show the lead levels in six contaminated water wells?
Marrrta [24]

Answer:

Option B, Barr graph

Explanation:

A bar graph is used for comparing several items all together based on any certain parameter.  

Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.  

A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.

Hence, option B is correct

Which of these is an example of a chemical change?
lawyer [7]

The correct options are, frying an egg and burning candle.

Explanation :

Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.

Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.

Frying an egg : It is a chemical change because a new substance is form by heating.

Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.

Boiling alcohol : It is physical change because only changes in the state.

Melting and ice : It is a physical change because only changes in the state.

Making coffee : It is a physical change because no new substance is formed.

Therefore, frying an egg and burning candle are the example of chemical change.

The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine
vesna_86 [32]

Answer:

The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.

Explanation:

Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.

The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:

  • <em>Adenine</em><em> is complemented with uracil, since in RNA the thymine is substituted by this uracil. </em>
  • <em>Thymine</em><em> is complemented with adenine. </em>
  • <em>Cytosine</em><em> is complemented with guanine. </em>
  • <em>Guanine</em><em> is complemented with cytosine. </em>

Thus an <u>uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T</u>.
