solve this equation 1/6x-2/3=1/2x-5/6
Answer:
1/2
Explanation:Subtracted 1/2 from 1/6 to get -1/3 x. Then add 2/3 to -5/6
Answer: No solution
Steps: ⅙x - ⅔ = ½x - ⅚
Subtract ½x from both sides: ⅙x - ⅔ - ½x = ½x - ⅚ - ½x
Simplify: -⅔ ≠ -⅚
They are not equal therefore there is no solution.

When a strand of dna was replicated, one base was left out. Why would this be more damaging than if the base was only changed?.
Leaving out a base during the process of replication is quite dangerous because this may result in a non-functional protein.
Incomplete proteinWhen a base is left out during replication and the mRNA generated is used to synthesize protein, the codons will be incomplete and will result in an incomplete or non-functional protein.
Codons are in a base of 3. Thus, leaving out a base means that an entire codon has been rendered useless. This also means that the amino acids of the protein synthesized will be incomplete.
This either results in a totally different or non-functional protein.

Based on ransom crossing, the genotypic and phenotypic ratio of offspring depends on whether each trait is dominant or recessive.
What determines the phenotype of offspring in a cross between parents?The phenotype of the offspring or filial generation of a cross is determined by the genotype of the parents and the nature of the allele of the genes in the parents, whether they are recessive or dominant.
When two true-breeding species of organisms are crossed, the phenotype of the offspring will be determined by the dominant trait.
For examples, if parental flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings are crosed, the genotypic ratio and the phenotypic ratio will be as follows:
GGLL × ggll = GgLl, GgLl, GgLl, GgLl
Phenotypic ratio = 1 Genotypic ratio = 1Where:
G = gray body is dominantg = ebony body is recessive L = long wings is dominantl = curly wings is recessiveTherefore, the genotypic and phenotypic ratio of offspring depends on whether each trait is dominant or recessive.

Aquifers located below the water table, important sources of freshwater, and located in the saturated zone.
What are aquifers?
Aquifers are underground, present layers of rock or sand that bear water.
Aquifers are bodies of permeable rock or sediment that have been flooded by groundwater.
As rainwater penetrates through the earth, groundwater enters an aquifer.
It has the ability to migrate through the aquifer and reemerge via springs and wells.
Thus, the correct option is D, all of the above.

1. Explain the concept of "natural selection" using your moths as an example (please use the data you collected to support your answer).
Answer: Natural selection can be seen in peppered moths, according to Tutt. In the gloomy bush, the brilliant moth's camouflage had worn off. Because dark moths live longer, they have more time to breed in a dark forest. All living creatures are impacted by natural selection. The peppered moth's evolution is an evolutionary example of moth population-directed color change as a result of industrial pollution.
The natural selection is based on the suitability and adaptation of an organism with that environment.
What is natural selection?Natural selection is the process in which populations of living organisms are selected by natural forces. Nature selects organisms that have traits better suited to the environment than others.
In conclusion, that organism will survive and reproduce that is suitable to that environment.

If fossils of fish and sea shells are found in an area that is now desert, we might assu
that:
• Fish could breathe air at one time in their history.
• Sea shells could live on land millions of years ago.
• The area in which the fossils were found was once covered with water.
• None of the above.
Answer:
The area once contained water.
Explanation:
Fish do not have the anatomical structures necessary for breathing on land. Even if they did, they would likely desiccate in the arid environment of the desert. The same reasoning applies to seashells. As a result, the environment must have been different in order to support the needs of these creatures. Since the Earth's continents are continuously shifting due to plate tectonics, and the Earth's climate changes over time, it would be reasonable to say that the desert was once a body of water that could support marine life.
The biosphere is part of the carbon cycle, but what if there were no biosphere? Is the biosphere necessary for the carbon cycle? In 3-5 sentences, explain why or why not. answer needed soon please help
Answer:
The carbon cycle describes the way the element carbon moves between the Earth's biosphere, hydrosphere, atmosphere, and geosphere. It is important for a few reasons: Carbon is an essential element for all life, so understanding how it moves helps us to understand biological processes and factors that influence them.
Explanation:
The biosphere is the ecosphere that contains the biotic and abiotic factors and the energy and the nutrient flow between them. It is the region of the earth that is composed of life and matter.
Yes, the biosphere is necessary for the carbon cycle.
The importance of the biosphere:The biosphere is essential as it maintains and provides the environmental circumstances for living organisms. The plants and animal-related activities that contribute to the carbon cycle occurs here.The plant in the biospheric region utilizes the carbon dioxide for the process of food and energy production while the animals release the carbon dioxide back into the atmosphere by the process of exhalation.Therefore, the biosphere is part of the carbon cycle.
