Answer:
<h2>D. Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>
Explanation:
As given here,
The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.
As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.
So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
Answer:
- <u>The hours are the independent variable.</u>
- <u>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked )
.</u>
- <u>The domain is 0 to 30
</u>
- <u>The range is 0 to 330
</u>
Explanation:
<em>The hours are the independent variable and should be plotted on the x-axis
.</em>
<em>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
</em>
<em>---------------
</em>
<em>Let +W+ = wages/wk earned
</em>
<em></em>
<em>Let +h+ = hours/wk worked
</em>
<em>The equation is:
</em>
<em>+W+=+11h+
</em>
<em>The domain is 0 to 30
</em>
<em>( no hrs worked to 30 hrs worked )
</em>
<em>The range is 0 to 330
</em>
<em>( no wages eared to +11%2A30+=+330+ earned )</em>
Compounds are made up of atoms that are bonded together. In a mixture, the atom or compound in the mixture are physically combined, therefore not bonded together. To put it simply, mixtures keep their properties while compounds do not.
<span>The geologic column is a graphic representation of the layers of rock that make up the earth’s crust. By compiling data from local areas, scientists have constructed a composite picture of the earth. Evolutionists would have us believe that this is also a picture of the 4.5 billion year history of the earth. Using a bit of circular reasoning, the geologic column is used as support for biologic evolution, which is then sometimes used to confirm the order of the layers in the geologic column.</span>
The right answers are : b. nitrogenous bases c. phosphates d. sugars.
Deoxyribonucleic acid (DNA) is the genetic information of most living organisms (on the other hand, some viruses, retroviruses, use ribonucleic acid (RNA) as genetic information).
- DNA is a polymer, made of units called nucleotides (or mononucleotides).
- The nucleotide consists of a phosphate + a sugar + a nitrogenous base. In DNA, the nucleotide is a deoxyribonucleotide (in RNA, the nucleotide is a ribonucleotide).
