The correct graphical representation of the organization levels of a biological system is as follows:
Cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. What is the level of organization of the biological system?The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.
A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.
Therefore, the correct graphical representation of the organization levels of a biological system is well represented above.

Indicate whether each of the following occurs mainly in G1 phase (G), S phase (S), or G2 phase (H) of the cell cycle. Your answer would be a four-letter string composed of letters G, S, and H only, e.g. HGSS. ( ) DNA helicase activation ( ) DNA helicase deposition on DNA at the replication origins ( ) ORC phosphorylation ( ) Licensing of replication origins
Answer:
the answer is S-G-S-G
Explanation:
DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.

When two parents heterozygous for genes for curly hair are crossed, what percent of their offspring would have curly hair? What percent would have straight hair?
Answer:
75% curly
25% straight
Explanation:
When two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.
What do you mean by Heterozygous?Heterozygous may be defined as the presence of two different alleles at a particular locus. It always includes one normal allele and one mutated allele.
Here, the allele for curly hair is dominant over the allele for straight hair. So, the offspring who carry the pure dominant and heterozygous alleles for curly hair would have the phenotype of curly hair, while the offspring who carry both the recessive allele would have the phenotype of straight hair.
Therefore, when two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?
Answer:
Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.
There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.

What is Digestive system?A collection of organs called the digestive system help break down food into smaller molecules that the body can absorb and use for energy, growth, and repair. It consists of anatomical organs such as the anus, esophagus, stomach, small and large intestine, liver, and pancreas. Food is broken down physically and chemically by the digestive system, which also absorbs nutrients and gets rid of waste.
Chemical process of digestive system involves Bile interacting with digested food in the small intestine, acids reacting with food particles in the stomach and saliva breaking down food particles while the mechanical process involves chewing of food.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

What process formed this delta?
Select one:
-A:erosion and deposition
-B :condensation and precipitation
-C:rock layer deformation
-D: shifting tectonic plates
Answer:
I think A
Explanation:
because erosion is the washing away of soil
Erosion and deposition are the formed on this delta. Thus, the correct option is A.
What is Erosion and deposition?Erosion is the action of the surface processes such as water flow or wind which removes the soil, rock, or dissolved materials from one location on the Earth's crust and then transports it to another location on the Earth's crust where it is deposited. The erosion is distinct from that of weathering that involves no movement.
Deposition is the laying down of the sediment carried out through the wind, flowing water, the sea or ice. Sediment on the Earth's crust can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by the organic activity such as sea shells or by evaporation.
Therefore, the correct option is A.
