Predict the effect of a mutation which limits the production of pigment in hair
The animal would have white hair or hair with no color.
The animal would have light brown hair.
The animal would have black hair.
The animal would have no hair at all.
The animal would have white hair or hair with no color is the effect of a mutation which limits the production of pigment in hair.
Mutation is the change in the genetic composition of the gene or genetic material which alters the normal functioning of the gene or the genetic material. In the given situation if the mutation occurs at the gene which is responsible for the production of protein pigment responsible for imparting color to the hair. Then it is expected that the gene does not encode for a protein pigment as a result the hair will remain without color or white.Hence, the animal would have white hair or hair with no color is the correct option.

What are the 3 components of an electromagnet?
Answer:
An electromagnet is a coil of wire wrapped around a bar of iron or other ferromagnetic material. When electric current flows through the wire, it causes the coil and iron bar to become magnetized. An electromagnet has north and south magnetic poles and a magnetic field.
Explanation:
The three main components of an electromagnet are the iron core, copper wire, and an electricity source.
What is an electromagnet?An electromagnet is a magnet in which a coiled or wrapped wire is given electricity. When Current is given to this wire, it acts like a magnet. An electromagnet is used to create a magnetic field.
The three main parts of the electromagnet are the iron core, that is the magnet, which is a small round, or square brick-like. The wire, wire, is made up of copper. The electricity source, by which electricity is given to the electromagnet.
Examples of electromagnets are induction cookers, doorbell rings, etc. They are controllable and adjustable magnets and are used in most electric appliances.

Which of the questions would involve the investigation of kinetic energy?
A. What material makes the strongest boat?
B. How does the color of a boat affect heat absorption?
C. Do boats float higher in salt or fresh water?
D. What is the effect of a boat’s shape on its speed?
Answer:
D. What is the effect of a boat’s shape on its speed?
Explanation:
Kinetic energy can be defined as the energy possessed by an object or body due to its motion. It is the amount of work required to accelerate an object or body with a specific mass from its point of initial rest to a final velocity.
Mathematically, kinetic energy (K.E) is equal to 1/2(mv²).
Hence, the question which would involve the investigation of kinetic energy is "what is the effect of a boat’s shape on its speed?" because speed is directly related to the motion of the boat. Generally, the shape of the hull of a boat has an effect on the speed of the boat.
Answer:
What is the effect of a boat’s shape on its speed?
A volume is measured experimentally as
4.09 mL. What is the percent error, given
that the correct value is 4.13 mL?
Answer in units of %.
Answer:
The answer is 0.97 %Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual volume = 4.13 mL
error = 4.13 - 4.09 = 0.04
We have
[tex]p(\%) = \frac{0.04}{4.13} \times 100 \\ = 0.968523002...[/tex]
We have the final answer as
0.97 %Hope this helps you

Melting can be best described as a process in which molecules
lose kinetic energy and move slowly.
lose kinetic energy and remain stationary.
gain kinetic energy and escape into the atmosphere.
gain enough kinetic energy to get past each other.
Answer:
Your answer is D (gain enough kinetic energy to get past each other.)
Explanation:
Melting can be best described as a process in which molecules gain enough kinetic energy to get past each other and the correct option is option D.
What is melting?
Melting is the process by which a substance changes from the solid phase to the liquid phase. Melting is also known as fusion, although this term has several meanings in science.
Melting occurs when the kinetic energy of a solid increases by application of heat or pressure, such that the molecules of solid start vibrating faster but stay close to their neighboring particles, rolling around each other. This particle movement allows the substance to flow and form a liquid.
Therefore, melting can be best described as a process in which molecules gain enough kinetic energy to get past each other and the correct option is option D.

Explanation:
In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson's discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?
Answer:
because it is a theory
Explanation:
The best explanation for why scientific theories are modified is simply because it is a theory. Theories are created as a set of suppositions that help humanity understand something that would otherwise be unexplainable. Since they are not proven through scientific facts but instead are more of ideas that help further our understanding of a phenomenon, they tend to be modified as new ideas are introduced and others are proven to be false/wrong.

Considering the reaction stoichiometry, from the balanced equation and reation stoichiometry, the number of moles of calcium oxide produced is 1 mole.
Chemical reactions are characterized by the appearance of new substances from others. That is, they are processes in which the nature of the substances changes, that is, from some initial substances called reagents, totally different ones called products are obtained.
In this case, you know that the balanced reaction is:
CaCO₃ → CaO + CO₂
Stoichiometry establishes relationships between the molecules or elements that make up the reactants of a chemical equation with the products of said reaction. In other words, stoichiometry determines the ratios between reactants and products in a chemical reaction.
The stoichiometry of a chemical reaction is perfectly established by the chemical equation. In it, the formulas of reactants and products appear preceded by numbers (the stoichiometric coefficients) that indicate the proportions according to which the transformation occurs.
The stoichiometric coefficients of a chemical equation are due to the fact that the atoms present before the reaction must be the same after the reaction, even though the atoms will have been rearranged to produce new substances.
In this case, by reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:
CaCO₃: 1 moleCaO: 1 moleCO₂: 1 moleIn summary, from the balanced equation and reation stoichiometry, the number of moles of calcium oxide produced is 1 mole.
