Which of the following statements about nucleic acids is true?
A. Nucleotides are made of a 5-carbon sugar, a nitrogen base, and a lipid.
B. DNA and RNA are examples of nucleic acids that are rarely seen in living things.
O C. Nucleic acids are made of repeating units called lipids.
O D. Nucleic acids store important information about cell division and the manufacturing of proteins and genetic information.
Answer:
D
Explanation:
nucleic acids( DNA &RNA). the DNA contains the genetic information of an organism while some RNA are used as messager within the cell. mRNA is usually sent to the nuclueoi to synthesis ribosomes, and ribosomes is the site of protein production in the cell.
29. A teacher presented the two models below to the dass. The models represent a eukaryote and prokaryote cell. The teacher asked the students to label the structure of each cell that contains the genetic code and
tell where it is located.
structure C, located in the cytoplasm in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the nucleus in Cell B
structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the cytoplasm in Cell B
Answer:
C. structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
Explanation:
This question contains images that depicts an eukaryotic cell (animal) and a prokaryotic cell (bacteria). According to the question, a teacher asked the students to label the structure of each cell that contains the genetic code (DNA) and tell where it is located.
In an eukaryotic cell, the genetic material (DNA) which contains the genetic code is located inside a well defined membranous structure called NUCLEUS while the genetic material in a prokaryotic cell is found naked in a region of the cytoplasm called NUCLEOID as they lack a membrane-bound nucleus. Based on this explanation;
- Structure C is the genetic material (DNA) which contains the genetic code of cell A (eukaryotic cell), hence, the genetic code of cell A is found in structure C, which in turn is located in the centrally-placed NUCLEUS.
- Structure C is the genetic material containing the genetic code of cell B (prokaryotic cell), hence, the genetic code of cell B is found in structure C, which in turn is located in the CYTOPLASM.

The bar graph that is essential to answer the question is attached with the answer:
Answer:
The correct answer is given as follows:
Explanation:
Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.
In this case: 37 is the mean value that can be calculated by:
adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259
Number of sets = 7
then mean = 259/7
= 37
Thus, the mean can be calculated by total value divided by the number of sets
what general type of mutation has the greatest effect on the protein produce
Answer: The most serious of these mutations will be the insertion of 2 bases. Becasue the genetic code is read in triplets, a 2 base insetion will alter the reading frame of the code causing a frameshift mutation meaning every amino acid after the site of the mutation will be incorrect.

What types of reactions are catalyzed by enzymes?
A. Hydrolysis
B. Dehydration Synthesis (also known as Condensation)
C. All of these
D. Other types of reactions
Answer:
is B. Dehydration synthesis
Explanation:
I hope this helps
The types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation. Thus, option B is correct.
What is dehydration synthesis?
When the level of water has been decreased the phenomenon has been known as the dehydration and the types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation.
Enzymes has been known as the biological catalyst that has been speed up the chemical reaction that use to carries out in the body. Enzymes are the protein by the nature and there are number of the enzymes present in our body such as the salivary amylase, pepsin, renin, lyases, lygases etc
The main function of the enzyme has to make the metabolism fast as well as speed up the chemical reaction carried out in the body. The best example of the enzyme has been salivary amylase which has an enzyme and it is present in the saliva and helps in the digestion of food.
Therefore, The types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation. Thus, option B is correct.
