identify the independent variable and dependent variable in the scientific method
The correct answer is the independent variable is one that you manipulate, control, or vary to investigate its effects and the dependent variable that being tested and measured in an experiment .
The simplest way to determine which variable in your experiment is the Independent Variable (IV) and which is the Dependent Variable (DV) is to put both variables in the sentence below in the correct order. "A change in the DV is caused by the IV." It is impossible for DV to cause any change in IV."
Example: Independent and dependent variables You plan a study to see if changes in room temperature affect math test scores. The temperature of the room is your independent variable. You change the temperature of the room by making it cooler for half of the participants and warmer for the other half.

Explanation:
Why are Hydrogen bonds similar to ionic bonds?
Answer:
Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. During an ionic bond one atom donates electrons to another atom. This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Explanation:
If the temperature increases then that will decrease the sugar but not the ATP and NADPH. So I predict that diuron will inhibit the photosynthesis because if photosystem II is infered with it then photosynthesis wouldn't work.And also, because paraquat will lower the NADPH and sugar but not ATP. Hence Diuron is the only choice left.

Under the right circumstances, the lysogenic cycle changes to the lytic cycle. Explain whether the lytic cycle can change to the
lysogenic cycle. Explain your answer in 3-5 sentences. (4 points)
The lytic cycle can change to the lysogenic cycle in the given manner discussed The lysogenic cycle allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( λ), can switch between the two cycles.
The lytic cycle:The lytic cycle infects a bacterium, captures the bacterium to make lots of cycles , and then kills the cell by making it explode (lyse).
The lysogenic cycle:The cycle infects a bacterium and inserts its DNA into the bacterial chromosome, permitting the cycle DNA (now called a pro phage) to be copied and passed on with the cell's own DNA.
Can lytic become lysogenic?During lysogeny, the pro phage will consist in the host chromosome until induction, which in the causes excision of the viral genome from the host chromosome. After induction has resulted the temperate phage could proceed through a lytic cycle and then undergoes lysogeny in a newly infected cell.
How lytic cycle is different then lysogenic cycle?The important difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell on contrary lysogenic cycle doesn't destroys the host cell. Where as Viral DNA destroys the host cell DNA and arrests cell functions in the lytic cycle.

Different amounts of light pass-through matter when it moves through it in different ways. Almost all of the light shining on transparent things can pass through them. Transparent items include glass, air, and clear plastic.
Burning plastics endangers flora, human and animal health, and emits hazardous chemicals into the environment, including dioxins, furans, mercury, and polychlorinated biphenyls (BCPs). Burning plastic releases extremely dangerous pollutants that greatly raise the risk of cancer, respiratory diseases, and birth problems.

3) Why should we store seed in moisture proof polythene bags
The orthodox seeds can be put in sealed moisture-proof containers after being dried to the proper moisture content. This avoids the need for prolonged dehumidification.
When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. Generally speaking, storage life shortens as seed moisture content rises. Low moisture level—below 4%—can also harm seeds due to excessive desiccation or result in hard seededness in some crops. If seeds are kept at high moisture content, losses could be very quick due to mould growth. The seed will mold as a result of the retained moisture, ruining the sample. Keep them cold and dry to increase their shelf life. Seeds quickly absorb moisture again. Keep seeds in airtight containers like tin cans or glass jars with tight fitting lids to maintain dryness.

When 2 or more spheres are changing matter or energy they are _________?
The correct answer is energy flow.
The principles of energy flow that govern how matter and energy move between the many domains are unique to each one. Energy goes from the perimeter to the center of a sphere, while matter moves from the center to the periphery.
The movement's speed and the separation between the spheres are the two main determinants of energy flow. The distance between the spheres determines the pace of matter movement, whereas the distance between the spheres determines the speed of energy movement.
The amount of energy that is available to be utilized in a certain situation depends on the pace at which energy is moving.

if we have more than 50% recombinant frequency in any case, then what
would be the best interpretation of that case?
A. Gene are present on same chromosomes
B. Genes are linked
C. Genes are having possibility of crossing over
D. Genes are present on different homologous pair
All options are correct, expect option B.
The frequency of a single chromosomal crossover occurring between two genes during meiosis is known as the recombination frequency. The measure used to describe recombination frequencies of 1% is the centimorgan (cM).Genes that are near to one another tend to be more connected than genes that are farther apart. The frequency of recombination will decrease with increasing linkage and vice versa. Linkage thereby lowers the frequency of the hybrid.A 50% recombinant frequency indicates that the genes are present on the same chromosome but are far from one another, suggesting that more than one crossover may have occurred during each meiosis. They might not be related because they are on different chromosomes. There is independent assortment in these genes.Therefore, all the options expect B. are correct.

These genotypes (BB or Bb) might both exist based on the information provided.
Individual Genotypes: Based on the information given, a geneticist is confident about the genotypes of the following people: The father of the brown-eyed man: The mother of the blue-eyed man with brown eyes is: bb Bb Brown-eyed man (because his mother could have only contributed a b allele to him) bb Blue-eyed woman Father of the blue-eyed woman (had brown eyes): Bb (for woman to have blue eyes, father must have contributed b allele) The mother of the blue-eyed woman had brown eyes.

Decomposers receive matter and energy from dead producers, consumers, and the waste they make. The matter is converted back into inorganic forms by decomposers so that it can be recycled into the ecosystem.
So, the energy that comes from sunlight entering an ecosystem eventually leaves the ecosystem as heat.
Energy and materials are transformed from one form to another in ecosystems.All of the objects in that environment, both living and nonliving, are referred to as matter.
