The perfect age to get a tattoo is 18 years.
Because the age of consent in the United States is generally between 16 and 18, the average age to get a tattoo is 17 and a half years old. Many individuals will dissuade kids from having tattoos, but they rarely explain why.
Because a minor's brain is still maturing, their decisions might be impulsive. They may come to regret their physical alterations, but it is equally conceivable that they will not. It's difficult to say, and it's better to be safe than sorry.

Explanation:
For what cellular function does the breathing rate help regulate?
Answer: The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood. brainliest?

Why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium??
Answer:
Soil is one of the main sources of nutrients needed by plants in order for them to grow. Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. Potassium helps plants make strong stems and keep growing fast. It's also used to help fight disease. Magnesium is the central core of the chlorophyll molecule in plant tissue.
Explanation:
Hope this helped a little bit.
Answer:
Explanation:
1.Without enough nitrogen in the soil the plant cannot grow taller, or produce enough food.
2.phosphorus results in higher grain production, improved crop quality, greater stalk strength, increased root growth, and earlier crop maturity. That is important because crops take up phosphorus only from the soil solution.
3.The role of Magnesium in the soil is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems.
4. Potassium is a critical nutrient that plants absorb from the soil, and from fertilizer. It increases disease resistance, helps stalks to grow upright and sturdy, improves drought tolerance and helps plants get through the winter. Potassium triggers activation of enzymes and is essential for production of (ATP).Both uptake of water through plant roots and its loss through the stomata are affected by potassium.

In bacterial cells treated with Mupircin, would you still expect to find large or small amounts of mRNA inside of the cell?
Answer:
Yes.
Explanation:
Yes, we can expect to find small amounts of mRNA inside the bacterial cell because the Mupirocin kills the bacteria by inhibiting transfer RNA. Mupirocin is an antibiotic used to kill the bacteria present on the skin. It destroys the cellular structure of bacteria and prevent the bacteria from causing more infection. Mupirocin do its antimicrobial activity by inhibiting isoleucyl-transfer RNA, as a result inhibiting of bacterial protein and RNA synthesis occurs.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.

Answer:
transport nutrients and water from below-ground tissues to above-ground tissues and grow taller.
absorb nutrients from the soil
Explanation:
The vascular tissues of plants is made of specialized conducting tissues the xylem and phloem.
This tissues form a continuous systems through the plant body and provide pathways for the transport of water, nutrients, signaling molecules and also provide support for plant body against mechanical stresses. The xylem transport water and nutrients from the roots to other parts of the plant while the phloem transport photosynthate the product of photosynthesis from the source where it is produced to other plant part.

Complete question:
You are studying a biochemical pathway in the mold Neurospora where enzyme 1 converts the initial substrate into intermediate substrate A; enzyme 2 converts intermediate substrate A into intermediate substrate B; enzyme 3 converts intermediate substrate B into intermediate substrate C; and enzyme 4 converts intermediate substrate C into the end product, an amino acid that is essential for growth. You isolate a mutant that is unable to grow on minimal media. Which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2?
a. The mold can grow on rich medium plus intermediate substrate C, but not on rich medium plus intermediate substrate B.
b. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus the initial substrate.
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
d. The mold can grow on rich medium plus intermediate substrate D, but not on rich medium plus intermediate substrate C.
e. The mold can grow on minimal medium plus intermediate substrate A, but not on minimal medium plus intermediate substrate C.
Answer:
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
Explanation:
Let us first diagram the pathway for a better understanding.
The normal organism produces four enzymes that convert substrates in the medium that allow it to survive, grow, and reproduce.
initial substrate ------------> A ----------------> B ----------------> C ----------------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
Any mutation on the Neurospora´s enzymes will not let the organism grow on the minimal medium because it will not be able to convert the minimal substrate into the following one, because the mutated enzyme will not accomplish its original function.
So if the mutation occurs in enzyme 1, the organism will not be able to convert the initial substrate into intermediate substrate A. And the rest of the reaction will not be possible either because of the lack of substance A.initial substrate -----X----> A -------X-----> B ------X--------> C ------X-------> AA
mutated Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 2, the organism will not be able to convert the intermediate substrate A into intermediate substrate B. And the rest of the reaction will not be possible either because of the lack of substance B.
initial substrate ------------> A -------X--------> B -------X------> C --------X-----> AA
Enzyme 1 mutated Enz. 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 3, the organism will not be able to convert the intermediate substrate B into intermediate substrate C. And the last reaction will not be possible either because of the lack of substance C.
initial substrate ------------> A ----------------> B -------X--------> C -------X------> AA
Enzyme 1 Enzyme 2 mutated Enz. 3 Enzyme 4
And if the mutation occurs in enzyme 4, the organism will not be able to convert the intermediate substrate C into the essential amino acid.
initial substrate ------------> A ----------------> B ----------------> C -------X-------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Mutated Enz. 4
But, if we artificially add to the medium the substrate that should be produced by the original enzyme (and that is not converted because of the mutation), then the organism will grow and survive because the other enzymes will be able to produce the essential amino acid.
So, if enzyme 2 is the only enzyme mutated, the organism will not be able to live in a medium with substrate A because the mutated enzyme will not convert the substrate A into B. There will not be B substrate in the medium, and the other enzymes will not produce the essential amino acid. So if the mutation occurs in enzyme 2, substrate A is useless to the organism because it will not survive.
But if we add the intermediate substrate B to the medium, the organism will survive. In a medium with substrate B, all the other reactions will be possible, and the organism will get the essential amino acid. The artificial addition of B substrate will replace the function of the original enzyme 2 -which is the one that converts A into B-.
