The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer?
A. phosphate backbone
B. thymine
C. nucleotide
Answer:
C. Nucleotide
Explanation:
There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.
A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;
A represents ADENINE
S represents SUGAR
P represents PHOSPHATE GROUP
Hence, the monomer is a NUCLEOTIDE.

You observe two distinct behavioral strategies among flocks of house sparrows. In one strategy, individuals (producers) search for food patches. In the other strategy, individuals (scroungers) wait for producers to find food and then feed in the patches found by the producers. The relative frequency of these strategies differs in flocks, and you observe that the scroungers have high fitness (a high feeding rate) when they are rare in a flock and low fitness when they are common in a flock. What is one possibility for the persistence of the two phenotypes in this population
Answer:
Frequency-dependent selection
Explanation:
Frequency-dependent selection is a type of natural selection where the fitness or reproductive success of a particular phenotype/genotype in the population is dependent on its frequency in the population. This type of natural selection can be both positive or negative. Frequency-dependent selection is a critical process that helps to maintain the genetic variability at population and species levels. A known example of frequency-dependent selection (positive) is the mimicry of butterflies, where selection can favor non-poisonous butterflies that show the same colors as poisonous butterflies.

The central dogma describes which of the following?
the process by which enzymes are modified after translation
the way DNA is replicated
the flow of genetic information
the way RNA is used as a template to make DNA
Answer:
The correct answer is - the flow of genetic information.
Explanation:
The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.
Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA into Protein. DNA → RNA → protein.
Thus, the correct answer is - the flow of genetic information.
The central dogma describes the flow of genetic information. The correct option is C.
A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.
This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.
The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.
Thus, the correct option is C.

Explain how stem cell therapy helped Lucy break down deoxyadenosine
Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.

Which factor contributed most to the development of the cell theory?
The factor that contributed most to the development of the cell theory is the advancement in technology.
With advancements in the area of technology, significant improvements were made to the primitive microscope initially invented by the likes of Hans and Zacharias Janssen, and more powerful microscopes like the electron microscopes were invented. With these, details of the cell could be observed and all the organelles could be studied, including how the cell divides (give rise to another cell).
Still on the technological advancement, the discovery of differential staining materials made it possible to differentiate several biological phenomena as they relate to the cell.
Thus, by extensively studying the cell using microscopes and differential staining dyes, the cell theory was developed by the likes of Theodore Schwann, Mathias Schleiden and Rudolf Virchow.
