Hierarchy is a theme of biology that we see in several different topics Genetics
is one such area. Which sequence has the terms in the correct sequence from
LARGEST to SMALLEST in terms of molecular size?
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
B. Chromosome, Nucleotide, Genome, Gene, Deoxyribose
C. Deoxyribose, Nucleotide, Gene, Chromosome, Genome
D. Genome, Gene, Chromosome, Nucleotide, Deoxyribose
Answers
Answer:
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
Explanation:
According to this question, genetics as a branch of Biology is not exclusive of hierarchical basis. The following is an orderly sequence from LARGEST to SMALLEST in terms of molecular size:
Genome - Chromosome - Gene - Nucleotide - Deoxyribose
- The GENOME constitutes the whole genetic make up of an organism. This includes all the chromosomes contained in that organism.
- CHROMOSOME is the structure on which the inheritable unit called GENE is found.
- GENE is the molecular unit of inheritance which is made up of nucleotides.
- NUCLEOTIDES are monomers of nucleic acids made up of pentose sugar (dexyribose or ribose), nitrogenous base, phosphate group.
- DEOXYRIBOSE is a five carbon sugar that forms part of the structure of a nucleotide.

within a cell, DNA is housed in the blank
Answers
Explanation
Within a cell, DNA is housed in the nucleus (in eukaryotic cells) or in the nucleoid region (in prokaryotic cells).
What is DNA?DNA (Deoxyribonucleic acid) is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms and many viruses. It is a long, double-stranded helical molecule composed of nucleotides, which are the basic building blocks of DNA.
Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine). The sequence of these bases determines the genetic code carried by the DNA molecule.
Thus, the DNA is housed in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells.

. Clots the blood,
Red blood cells
White blood cells
Plasma
Platelets
Answers
Answer:
Platelets help the blood clotting process (or coagulation) by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur. This results in the formation of a fibrin clot, which covers the wound and prevents blood from leaking out.
Explanation:
Blood is composed of plasma, red blood cells, white blood cells, and platelets. Blood platelets play a role in coagulation (the clotting of blood to stop bleed from an open wound); white blood cells play an important role in the immune system; red blood cells transport oxygen and carbon dioxide.

Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

T,Q,R,S

Q,R,S,T
S,R,Q,T
Answers
Reasoning: T is hit with the most pressure then Q then R and S
The picture shows a turgor pressure demonstration using stalks of celery in different salt solutions, so based upon the one with the most turgor pressure to the one with the least turgor pressure, T, Q, R, and S are in option A.
What is turgor pressure?Turgor pressure is the pressure exerted by water inside the plant cells against the cell wall. When the water flows into the cell due to osmosis, the cell becomes turgid, and the cell wall becomes stiff. In the given experiment, celery stalks are placed in different salt solutions, which affect the water potential of the cells. When the celery stalk is placed in a salt solution with a higher concentration of solutes than the cell sap, water molecules will move out of the plant cell by osmosis. This causes the plant cell to lose water and become flaccid.
Hence, based on the ones with the most turgor pressure to the ones with the least turgor pressure, T, Q, R, and S are in option A.

They are typically unicellular but can also be multicellular or colonial. Protists can be found in a variety of environments, including freshwater, marine, and soil, and can be free-living or symbiotic. They are an ancient group of organisms, and some of the earliest eukaryotes were likely protists.
The diversity of protists is immense, and they exhibit a wide range of characteristics and behaviors. Some protists are photosynthetic, using pigments like chlorophyll to capture sunlight and convert it into energy. Others are heterotrophic, consuming other organisms or organic matter. Some protists are capable of moving through their environment, using structures like flagella, cilia, or pseudopodia to propel themselves. Because of their diversity and importance in many ecosystems, protists are an important area of study in biology.

Many eukaryotic cells can be grown in tissue culture in the laboratory. Suppose you have two tissue cultures, one in G1 phase and one in S
phase. How would you determine which culture was in G, and which was in S?
Answers
I could look for growth and synthesis of proteins and other macromolecules as well as increase in organelles, which would show a culture in G1. DNA being synthesized would show in cells in the S phase.
The best way to determine if the cell is the G or S phase is by looking at the state of the DNA molecule, and the presence of histones, centrioles, and spindle fibers.
What is the interphase?
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage.During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.To determine which culture was in G stage, and which was in S stage, I would look at DNA molecule. The only stage in which DNA duplicates is during the S phase, so
If organelles are duplicated but not DNA, it is G1 stageIf organelles are duplicated as well as DNA, but the molecule is still lax, it is S phase. At this point there are also histones.If organelles are duplicated and DNA molecule began to condensate it is G2 phase. At this point there are also centrioles and spindle fibers.You can learn more about the interphase at
