Answer:
The correct answer would be - c) its genome is 23% thymine (T)
Explanation:
The rule of Chargaff says that the amount of the adenine (A) and thymine (T) is almost equal and guanine (G) to cytosine (C) and also the amount of A and T should be equal to the amount of the G and C.
So, A= 23 % then T must be 23 %
Then, A+T = 46%.
The left 54% should be divide by 2, G and C that would be 27 %.
So, the correct option is C.
If the genome of an organism is 23% adenine (A), then its genome is 23% thymine (T).
DNA:
DNA or deoxyribonucleic acid is a biological molecule that stores genetic information in living cells. DNA is structurally made up of nucleotides namely: adenine, thymine, cytosine and guanine. According to Erwin Chargaff, the amount of adenine in the DNA is equal to thymine while the amount of guanine is equal to cytosine i.e. A - T, G - C. Therefore, If the genome of an organism is 23% adenine (A), this means that its genome is also 23% thymine (T).Learn more about DNA composition at: https://brainly.com/question/13049777?referrer=searchResults

Which statement is true?(1 point) Proteins and carbohydrates have the same amount of energy. Fats have a lower amount of energy than carbohydrates. Fats and proteins have the same amount of energy. Carbohydrates have a higher amount of energy than proteins.
Answer:
The correct statement is that proteins and carbohydrates have the same amount of energy.
Explanation:
The 90 percent of the dry weight of the diet and 100 percent of its energy is supplied by proteins, carbohydrates, and fats. All these macronutrients provide energy to the body, however, the amount of energy in one gram varies, that is, 9 calories in a gram of fat, and 4 calories in a gram of protein or carbohydrate.
These nutrients also vary in the rate by which they supply energy. Of the nutrients, fats are the slowest and carbohydrates are the quickest.

Genetic engineering involves modifying the genetic material of an organism, such as bacteria, to introduce new characteristics or functions. One application of genetic engineering is to use bacteria to produce human proteins, which can be used for various medical purposes such as in vaccines or as therapeutic agents.
What is the first step for the process ?Isolate the gene for the human protein: The first step in genetically engineering bacteria to produce a human protein is to identify and isolate the gene that codes for the protein. This can be done using various techniques, such as polymerase chain reaction (PCR) or DNA sequencing.
Insert the gene into a bacterial vector: Once the gene for the human protein has been isolated, it is inserted into a bacterial vector, which is a small circular piece of DNA that can replicate independently within the bacterium. The vector is usually a plasmid, which is a type of DNA that can be easily manipulated and introduced into bacterial cells.
Introduce the vector into bacteria: The next step is to introduce the vector carrying the human gene into the bacteria. This can be done using various techniques such as electroporation, heat shock, or transformation.
Allow the bacteria to produce the protein: Once the vector carrying the human gene is inside the bacterial cell, the cell can begin to produce the human protein. The bacterial machinery reads the genetic code in the gene and synthesizes the protein.
Extract and purify the protein: After the bacteria have produced the protein, it can be extracted and purified. This involves breaking open the bacterial cells to release the protein, and then using various purification techniques to isolate and purify the protein.
Test the protein for activity and safety: Finally, the purified protein is tested to ensure that it is active and safe for use in humans. This can involve various assays and tests to confirm the protein's function and purity.
In summary, genetic engineering can be used to introduce the gene for a human protein into bacteria, allowing the bacteria to produce the protein, which can then be extracted, purified, and tested for medical use. This process can be used to produce a wide variety of human proteins, including hormones, enzymes, and antibodies.

Morning commuter traffic in cities contributes to ____ smog. In this type of air pollution, a mixing of ____ from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
Answer:
photochemical
hydrocarbon
Explanation:
Morning commuter traffic in cities contributes to photochemical smog. In this type of air pollution, a mixing of hydrocarbons from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog

Which of the following is the best explanation why is the Earth's inner core solid?
Question 2 options:
The particles are no longer moving as fast because it has cooled to a solid.
Because the inner core is the same temperature as the sun.
Because it's made of a mixture of iron and nickel which are only found in a solid state.
The pressure from the other layers of the Earth cause the inner core to be solid.
Answer:
The pressure of all the other layers makes it solid
Explanation:
The weight is so great, it is solid
The pressure from the other layers of the Earth causes the inner core to be solid. So the correct option is D.
What are the layers of the Earth?The Earth is more complex than what we can currently perceive. The Earth actually has several layers, as you might see if you could divide it in two and hold it in your palm. However, we still have some secrets about the interior of our globe. The inside of our planet is still beyond limits to humanity, despite our daring explorations of other planets and the placement of satellites in orbit.
However, improvements in seismology have made it possible for us to understand a lot about the Earth and the many strata that make it up. Numerous essential processes on our planet are influenced by the features, content, and characteristics of each layer. The crust, mantle, outer core, and inner core are the layers in ascending sequence from the outside to the inside of the earth. Let's examine them and see what they are doing.
The Earth's interior is differentiated, much like all terrestrial planets. This indicates that its underlying structure is made up of layers that are organized similarly to the skin of an onion. One layer can be peeled back to reveal a second layer that differs greatly from the first in terms of temperature, pressure, and chemical composition.
Therefore the correct option is D.

Which of the following is the best description of how electrons are transferred in an ionic bond?
A. A metal atom loses electrons and a nonmetal atom gains electrons.
B. A metal atom gains electrons and a nonmetal atom loses electrons.
C. A metal and a nonmetal atom lose electrons.
D. A metal and a nonmetal atom gain electrons.
Answer:
A. A metal atom loses electrons and a nonmetal atom gains electrons.
Explanation:
An ionic bond is defined as the force of attraction between positive and negatively charged electrons.
An ionic bond is formed when a metal atom loses its electrons to atoms of a nonmetallic element. For example: Sodium Chloride (NaCl), where an atom of sodium (Na) donates an electron to an atom of chlorine (Cl) to form an ionic bond.
Hence, the correct answer is "A. A metal atom loses electrons and a nonmetal atom gains electrons."
