What does the MC1R gene code for

Answers

The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. This receptor plays an important role in normal pigmentation. The receptor is primarily located on the surface of melanocytes, which are specialized cells that produce a pigment called melanin.

2. Consider the table of boiling points and structural isomers. Note that butane has two possible isomers but that decane has 75 possible isomers. Why does the number of possible isomers go up with an increasing number of carbon atoms?

Answers

Answer:

because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain

"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."

What is isomer?

Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.

"Is air pollution related to lichen growth?"

What is a likely hypothesis for the question?

A. Air pollution must affect lichen growth.

B. No, air pollution does not affect lichen growth.

C. If air pollution is high, then lichen growth is high.

D. If air pollution is high, then lung disorder cases are high.​

Answers

Air pollution must affect lichen growth because lichens have no roots they get all their nutrients from the air. If the air has pollutants that can become toxic for lichens.

What are lichens?

A lichen can be described as a composite organism that arises from algae or cyanobacteria living among filaments of fungi species in a mutualistic relationship. Lichens have different properties that come in many colors, sizes, and forms.

A macro lichen can be defined as a lichen that is either bush-like or leafy.  Lichens do not have roots therefore they absorb water and nutrients as plants do  but like plants, they form their own nutrition by photosynthesis.

If lichens are exposed to air pollutants they are unable to avoid the accumulation of air pollutants. Because lichens possess no roots, their primary source of most nutrients is the air.

Lichen decline can be because of the accumulation of toxic substances as well as altered nutrient supplies that favor one symbiont over the other. Therefore, option (A) is correct.

Chemistry question on enthalpy HELP!!!!

Answers

Answer: The enthalpy change for this reaction is, -803 kJ

Explanation:

The balanced chemical reaction is,

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)][/tex]

[tex]\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{CH_4}\times \Delta H_{CH_4})][/tex]

where,

n = number of moles  

Now put all the given values in this expression, we get

[tex]\Delta H=[(1\times -394)+(2\times -242]-[(2\times 0)+(1\times -75)][/tex]

[tex]\Delta H=-803kJ[/tex]

Therefore, the enthalpy change for combustion of methane is, -803 kJ

When developing a product such as cookware specific heat well as health cost and ease of use our important factors to consider one of the materials tested which is the best suited for cookware and why explain based on safety/health cost specific heat and ease of use

Answers

Answer:

In short, the thermal conductivity of a material is how readily that material absorbs and transmits (releases) energy. When the fire or heating element of a range comes in contact to a pan, the energy from the heat source is transmitted to the pan. This increases the internal kinetic energy of the pan (commonly called "heating up"). The heated material then transmits the energy to nearby materials that are at a lower average molecular kinetic energy level (at a lower temperature than the material). The higher the thermal conductivity of the material, the faster it will heat up and also, the faster the heated area will spread to unheated areas of the same piece of material.

For example, if we placed a large sheet of stainless steel (fairly low thermal conductivity as cooking materials go) on a burner and turned on the burner, the area directly under the burner would get hot while the rest of the sheet slowly heats up. The burner imparts heat quickly only to the region of steel directly over it. The rest of the pan heats up from the conduction of the heat from that spot. When the outer edges of the sheet have reached a hot temperature, the spot directly over the burner would be extremely hot. The figure below shows an example of the temperature of the sheet of steel over a gas burner. The hottest parts are shown in white, hot is red and cool is blue.

The answer is the D. "Observation" is not a variable in an experiment.
Explanation: Research variables are factors that can be manipulated, measured or those that we try to explain through other variables. "Observation" is not a variable in an experiment, but it is the first step and fundamental part in the scientific method, in which the experiments are contained (experimentation stage). Observation is the information recorded during an experiment, obtained through the senses or through the registration of information on scientific instruments.

An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.5×107 m/s. If the velocities of individual neutrons are known to within 2.0% of this value, what is the uncertainty in the position of one of them?

Answers

Answer:

4.54 * 10^-14 m

Explanation:

From Heisenberg's uncertainty principle, we can write;

Δp.Δx ≥ h/4π

Given that;

Δp =Δmv

So;

Δmv.Δx ≥h/4π

Δmv =2/100(3.5×10^7 m/s * 1.66 * 10^-27)

Δmv =1.162 * 10^-21 Kgms-1

Δx ≥6.63 * 10^-34 /4 * 3.142 * 1.162 * 10^-21

Δx ≥4.54 * 10^-14 m
