Which of the following best describes how a liver cell and skin cell have the exact same DNA
sequence and yet look different and perform different functions? (1 point)
O The cells mutate during transcription.
O The cells discard the DNA that is not in use.
O The tRNA uses a different sequence in each cell during transcription.
O The proteins are expressed differently in each cell.
Answers
Though not exact, the statement that best describes how a liver cell and skin cell have the exact same DNA sequence and yet look different and perform different functions is the last one, the DNA is expressed differently, which leads to proteins being "expressed" differently in each cell.
During early embryonic development, the few cells that make up our organism are totipotent in nature. A totipotent cell is one with the capability to produce any tissue in the human body. All the cells that later make up our bodies are derived from these.
This explains that although not all of the DNA sequence is expressed at all times, the DNA is still present in the cell, meaning that option 1 is false. Option 2 is also false due to the fact that although mutations can occur from time to time, they are certainly not a common process nor are they normal. Finally, option 3 is false given that tRNA's only role is to apport the correct amino acid for each sequence.
As development continues, cells specialize into specific tissues. They do this by compressing certain areas of their DNA, making it unreadable and therefore limiting the expression of that area of the genetic code. This causes the proteins that are synthesized to be unique for each type of tissue.

Which of the following are sustainable wastewater methods?
1. Graywater used to water yards
II. Chlorination and ozonation disinfection
III. Use of artificial wetlands
Answers
Answer:
1, II, and III
Explanation:
The one that are sustainable wastewater methods are chlorination and ozonation. The correct option is B.
What is chlorination?The procedure of adding chlorine to potable water to inhibit bacterial, microbes, and viruses is known as chlorination. To achieve safe levels of chlorine in drinking water, various processes can be used.
One of the most powerful oxidants is ozone, a gas composed of three oxygen atoms (O3).
Ozonation is a sort of advanced oxidation process that generates highly reactive oxygen species capable of attacking a wide range of organic compounds as well as all microorganisms.
Drinking water purification processes include chlorination and ozonation.
When compared to chlorination, ozone has a higher disinfection effectiveness against bacteria and viruses.
Furthermore, the oxidizing properties can reduce the concentration of iron, manganese, and sulfur, as well as reduce or eliminate taste and odor issues.
Thus, the correct option is B.

what is it called when light passes directly through cells?
Answers
Explanation:
Light microscopes allow for magnification of an object approximately up to 400-1000 times depending on whether the high power or oil immersion objective is used.
Light microscopes use visible light which passes and bends through the lens system.
Electron microscopes use a beam of electrons, opposed to visible light, for magnification.
Electron microscopes allow for higher magnification in comparison to a light microscope thus, allowing for visualization of cell internal structures.
Key Terms
resolution: The degree of fineness with which an image can be recorded or produced, often expressed as the number of pixels per unit of length (typically an inch).
electron: The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.

Darwin's Theory of Natural Selection
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive.
Phenotypic variation exists among individuals and the variation is heritable.
Those individuals with heritable traits better suited to the environment will survive.
When reproductive isolation occurs new species will form.
These are the basic tenets of evolution by natural selection as defined by Darwin. The following is a quote from Darwin.
"Variation is a feature of natural populations and every population produces more progeny than its environment can manage. The consequences of this overproduction is that those individuals with the best genetic fitness for the environment will produce offspring that can more successfully compete in that environment. Thus the subsequent generation will have a higher representation of these offspring and the population will have evolved.

What changes occur in the anaphase stage of the cell cycle?The fourth stage of mitosis is known as anaphase.Divides the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells. The sister chromatids, or replicated chromosomes, are positioned along the equatorial plane of the cell before anaphase starts. The sister chromatids are made up of two identical DNA copies linked at the centromere.Each pair of chromosomes divides into two identical, independent chromosomes during anaphase. The mitotic spindle is a structure that separates the chromosomes. A chromosome is attached to one end of the mitotic spindle's many lengthy proteins, known as microtubules, and a cell pole is attached to the other. At their centromeres, the sister chromatids split simultaneously. The spindle subsequently drags the split chromosomes to the cell's opposite poles.To learn more about the anaphase stage of the cell cycle, refer to https://brainly.com/question/13766396?referrer=searchResults
