Which is the term for the different forms of a gene for a given trait?
Answers
Answer:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Define orbit and orbital motion, and explain why orbital motion occurs.
Answers
Answer:
Orbital motion occurs whenever an object is moving forward and at the same time is pulled by gravity toward another object. ... The result is a circular or oval path called an orbit, in which one object keeps moving around the other. Because of the relatively great gravity of the sun, Earth orbits the sun

Answers
Answer:
a. Indivisible.
b. Mass.
c. Masses.
d. Compound.
e. Elements.
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
Hence, all the physical properties of a mineral result from the mineral's internal arrangement of atoms.
The following are statements postulated by the Dalton's atomic model;
a) Elements are composed of minute, indivisible particles called atoms.
b) Atoms of the same element are alike in mass and size.
c) Atoms of different elements have different masses and sizes.
d) Chemical compound are formed by the union of two or more different atoms of different elements.
e) Atoms combine to form compounds in simple numerical ratios, such as one to one, one to two, etc.
f) Atoms of two elements may combine in different ratios to form more than one compound.

Answers
Answer:
if you will decrease the HCO3- so the less H+ ion will be form and reaction will more likely shift to product and when HCO3- decreases pH value increases and vica versa for the increasing HCO3 the more H+ ion will be form and reaction will shift to product and the pH value will decreases!!
I've doubt in reaction shift coz whatever is the amount of HCO3- this is completely gonna form number of H+ so reaction shift may or may not be same!!

What is the potential energy of a rollercoaster if it weighs 1565 kg and sits on a 115 m tall ride?
Answers
Answer:
Explanation:
Potential energy builds as the coaster is going up the loop-the-loop and converts to kinetic energy on the way down and out of the loop-the-loop. The potential energy of the coaster is at its lowest and the kinetic energy is at its highest as the coaster moves in the lowest point of the loop-the- loop.

H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide
Answers
Answer:
Explanation:
Find the molar mass of H2SO4
2H = 2 * 1 = 2
S = 1 * 32 =32
O4 = 4*16 = 64
total 98
Find the number of mols in 71.5 grams
mols = given mass / molar mass.
given mass = 71.5
molar mass = 98
mols = 71.5/98
mols = 0.7296 mols of H2SO4
Find the moles of H2O
From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O
mols water = 2 * 0.7296
mols water = 1.4592
That's as far as I can take you. I have to know a great deal more to get the volume of H2O

How many militias of 5.0 M H2SO4 (aq) stock silly toon are needed to prepare 100. Ml of 0.25 M H2SO4 (aq)
Answers
Answer:
5 mL
Explanation:
As this is a problem regarding dilutions, we can solve it using the following formula:
C₁V₁=C₂V₂Where subscript 1 refers to the initial concentration and volume, while 2 refers to the final C and V. Meaning that in this case:
C₁ = 5.0 MV₁ = ?C₂ = 0.25 MV₂ = 100 mLWe input the data:
5.0 M * V₁ = 0.25 M * 100 mLAnd solve for V₁:
V₁ = 5 mLAnswer:
5 mL of 5.0 M H₂SO₄ (aq) are needed to prepare 100 mL of 0.25 M H₂SO₄ (aq).
Explanation:
In chemistry, dilution is the reduction of the concentration of a chemical in a solution.
Then, dilution consists of preparing a less concentrated solution from a more concentrated one, and it consists simply by adding more solvent to the same amount of solute. That is, the amount or mass of the solute is not changed, but the volume of the solvent varies: as more solvent is added, the concentration of the solute decreases, since the volume (and weight) of the solution increases.
A dilution is calculated by the expression:
Ci*Vi = Cf*Vf
where:
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volumeIn this case, you know:
Ci=5 MVi= ?Cf= 0.25 MVf= 100 mLReplacing:
5 M*Vi = 0.25 M* 100 mL
Solving:
[tex]Vi= \frac{0.25 M*100 mL}{5 M}[/tex]
Vi= 5 mL
5 mL of 5.0 M H₂SO₄ (aq) are needed to prepare 100 mL of 0.25 M H₂SO₄ (aq).

A certain type of material allows electricity to flow through it, but it does not flow quickly or easily through it. Is the material a good or poor conductor? Does it have a low or high resistance?
Answers
Since such a material resists the flow of electric charge, the material can be said to have a high resistance (or high resistivity).
Mathematically, resistance and conductance are reciprocals of one another; a low conductance implies a high resistance, and a high conductance implies a low resistance.
