Explanation:
Hoped this helped have a good day, brainlist?
Hydrogen, Phosphorus, Nitrogen was most likely DNA.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA inside mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the nutrients in food into the a form that can be utilised by cells.
Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.
Thus, Hydrogen, Phosphorus, Nitrogen was most likely DNA.

Answer:
Quaternary structure
Explanation:
Quaternary structure insinuates the number and game-plan of the individual polypeptide chains. Each polypeptide is suggested as a subunit of the protein. Comparative powers and bonds that make tertiary structure moreover hold subunits together in a consistent eccentric to shape the complete protein.

What is the difference between genetic and species diversity?The primary difference between genetic diversity and species diversity is that genetic diversity refers to differences in DNA that may be found across individuals of the same species
Whereas species diversity refers to the number of different species that can be found in a certain region. The term "ecological diversity" refers to the range of ecosystems that may be found in a certain region.
A given species' capacity to adapt and spread across a variety of environments is facilitated by genetic diversity. Diversity of species fosters biotic interactions and community stability.

Your body has a layer of skin that protects it from the environment. This layer of skin is made up of many individual skin cells. Explain where all the cells came from and how two individual cells share the same traits.
Stratum Corneum This layer is composed of the many dead skin cells that you shed into the environment—as a result, these cells are found in dust throughout your home. This layer helps to repel water.
The cells of the skin layer that protects the body came from preexisting cells.
This is according to the cell theory which states that:
cells are the basic unit of lifecells arose from existing cells by reproductionall living organisms are made of cellsCells can only arise from existing cells by a reproductive process known as cell division. Cells can divide by mitosis if they are vegetative cells or by meiosis if they are sex cells.
The daughter cells produced in meiosis are usually genetically and phenotypically different from their parent cells, unlike mitosis where the daughter cells are essentially the same as the parent cells both genotypically and phenotypically.
The cells of the skin are vegetative cells. Thus, they can only reproduce by mitosis. This is why individual skin cells share the same trait.

1. Why is it advantageous for scientises to test only one variable at a time during an experiment? 2. Distinguish between a variable and a control. 3. What is differentiation? 4. What are some advantages ande disadvantages of light microscopes and electron microscopes? 5. Explain why you cannot draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled.
Answer:
It is advantageous because the fewer variables are presented, the simpler the investigation and the more concrete the hypothesis will be.
A variable is that quantitative data that is modified or varies over time, it must be quantifiable, reasonable, and its variability must be expressed by means of indices, while the control group is the group that is controlled and compared. with other research groups to be able to relate cause-effect or risk factors by exposing them to the agent of the problem, while the researcher observes.
Differentiation is the process by which it is sought to find the differences in the investigation.
The advantages of electronic and optical microscopes is that we can observe very small beings, such as microbiological, or infected tissues, or even tissues to evaluate their histological architecture, they are very important for science and the medical professions, they are adjustable before different cephalometric morphologies, In other words, they can be adapted according to the size of the user to make it more comfortable.
The disadvantages are that the optical microscope cannot see very small microorganisms, such as some viruses and bacteria, and also has much less definition and sharpness than the electronic one, its costs are high, its CORRECT use is difficult to learn and teach, maintenance it is rigorous and delicate.
If the other variables are not controlled, then all the variables would be a possible cause or effect factor of a conclusion, that is, if we do not control the variables, we cannot propose a certain conclusion, effects or hypothesis, since the risk of The error is very high and the conclusions obtained from the uncontrolled variables will have little certainty or credibility.
Explanation:
Ls variables in an investigation can be dependent or independent.
It depends on the role they fulfill in the research, they can also be classified as homogeneous or heterogeneous, provided that one raises a main problem, a solution tree, takes into account variables that are selected to be able to face in the research. These investigations must be homogeneous, in order to provide more certainty in the hypothesis or in the conclusion.
That a variable is homogeneous means that it covers most or all the variances of a population, and is the most comprehensive or representative in a logical and reasonable way to what you want to investigate.

Explain how the reduction and rearrangement are accomplished in meiosis.
Answer:
Reduction is accomplished by (homologous) chromosomes pairing and then separating to move to opposite poles during the 1st meiotic division. ... Rearrangement is achieved by the chromosomes crossing over into random alignments of tetrads, resulting in the genetic variation of the offspring.

The type of cell division that allows the formation of cells with half of the genetic information of the dividing cell is known as meiosis, the reduction and rearrangement are accomplished in the following way:
Chromosome reduction occurs as a cell division process in which a diploid (2n) cell undergoes two successive divisions, generating haploid (n) cells.These cells called gametes have half the DNA of the rest of the individual's cells, this half of DNA is not random, but is precisely a complete chromosomal set.This halving allows the number of chromosomes of the species to be maintained at fertilization.Rearrangement occurs before chromosomes separate, corresponding sections of chromosomes can change, or cross, between the pair.Through recombination and random segregation, each pair of homologs obtains a mixed paternal and maternal chromosome, thus producing a new haploid chromosome set or set in which new combinations of genes have originated.The rearrangement of DNA increases genetic diversity within a population by passing genetic information to the next generation, which is not completely identical to that of the father.Therefore, we can conclude that meiosis is one of the ways in which cells divide, characterized by giving rise to daughter cells that are genetically different from the cell that originated them through chromosome reduction and rearrangement.

The regularity of El Niño weather events is determined by
A the amount of gases that volcanoes create each year on the seafloor near Australia.
B changes in the size of a warm podl of water in the seas near Indonesia.
C a decrease in the frozen glaciers at Earth's poles.
D the magnetic strength of Earth's inner core.
Answer: The answer is B
Explanation:
This is a known knowledge about how hurricanes form. It's the same with El Nino, Good Luck.
A decrease in the frozen glaciers at Earth's poles can be the event by which we can determine the regularity. Correct option is C.
The term El Niño refers to a warming of the ocean surface in the central and eastern tropical Pacific Ocean.
Niño occurs when warm water builds up along the equator in the eastern Pacific areas. The warm ocean surface increase the temperature in the atmosphere, which allows moisture-rich air to rise and develop into rainstorms.
Therefore, a decrease in the frozen glaciers at Earth's poles can be the event by which we can determine the regularity.
