Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.
A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. Which would be the order of the bases on the opposite strand of DNA?
cytosine, adenine, adenine, and thymine
cytosine, thymine, thymine, and adenine
thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine
Answer:
thymine, guanine, guanine, and cytosine
Explanation:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairingThe deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

PLS HELP!!! PROJECT DUE IN 30 MINUTES!!
Answer:
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. ... Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover.

Cellular differentiation is when a cell changes from one cell type to another—usually, the cell changes to a more specialized class. Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and average cell turnover.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.
Answer:
It is B
Explanation:
I had this question on my test last week
The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).
An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.The linear sequence of amino acids within a protein is the primary structure of proteins. The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.The most common tertiary structures of the proteins are globular and fibrous structures.Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

How did Concorde fly so high?
Concorde fly so high because the higher it flew, the thinner the air was that it encountered. This consequently led to less drag and fuel burn.
Did the Concorde fly in the stratosphere?

Describe how the process of natural selection can result in an increase in frequencies of certain traits found in a population.
Answer:
Natural Selection (Answer Below)
Explanation:
Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability
1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.
