Answer:
C. A perfect, mutation-free society
Explanation:
Mutation is a genetic phenomenon involving the alteration or change in the genetic sequence of a gene. Mutation is commonly caused by mutagens (chemical substances that induce mutation), DNA replication mistakes or errors etc.
According to this question, if DNA replication occurs without error, this means that mutation will likely not occur, leading to a perfect, mutation-free society.
What is the general pattern of magma circulation in the mantle?
Answer:
Observe : Earth's mantle is a zone of semi-molten rock, or magma, found between the solid crust that makes up Earth's surface and the molten rock in Earth's outer core. ... What is the general pattern of magma circulation in the mantle? Moves up and down. 2.
The general pattern of magma circulation in the mantle is ; upwards and downwards towards the earth crust
The mantle is situated between the solid crust making up the earth surface and Earth's outer core and it is made of molten rocks which are heated up due to high pressures.

A 1500 kg car sits on top of a car carrier truck 2.5 meters above the ground how much potential energy does the car have
Answer:
36,787.5 Joules
Explanation:
Potential Energy = mass * acceleration due to gravity * height
U = mgh
We know the following:
mass = m = 1,500 kg
acceleration due to gravity = g = 9.81 m/[tex]s^{2}[/tex]
height = h = 2.5 m
When we substitute each value into the formula we get the following:
U = 1,500 kg * 9.81 m/[tex]s^{2}[/tex] * 2.5 m = 36787.5 kg[tex]\frac{m^{2}}{s^{2} }[/tex] = 36,787.5 Joules

For each of the following minerals, say what properties of the material make it important in carrying out it's particular function.
a. tar roads
b. iron bulgar bars
c. plastic furniture
d. metal jewellery
e. clay for building
f. cotton clothing
Answer:
1. Tar Roads: The qualities of Tar that makes it ideal for road construction are:
The tar-like material that is used for road construction is a combination (emulsion) of water and liquid asphalt. It serves the purpose of permeating and closing up small lacerations in the existing pavement.
When the emulsion sticks to the "gravel" it reduces the potential for vehicles to skid on the road thus enhancing safety. The "gravel-like" emulsion is applied by rolling and sweeping.
Qualities of Tar are:
Adhesive: its the ability to stick to surfaces including materials such as gravel which it holds together makes it great for road construction;Waterproof: It is not water-soluble. Hence is not easily susceptible to the effects of running water. Resistant to High Temperature: The melting point of Tar is 54 degrees centigrade. The ground can heat up to 45 degrees celsius thus making Tar perfect for road construction as it can remain rigid even in the worst temperatures.2. Iron Burglar Bars
Steel bars are made from iron. The qualities of steel which make it perfect for securing places and things are:
Strength; This is the ability to withstand breakage and or destruction. Toughness: Steel is very tough and can not easily bend or break under static loads. Weldability: Most steel bars are actually welded together. Without this ability, steel probably would be useless as a material that can be used for protectionDurability: The only factor that degrades steel is rust. Rust happens when steel is exposed to oxygen which can be found in air and water.3.) Plastic Furniture
The primary qualities of plastic that make them suitable for furniture are:
Chemical stability: It does not rust or degrade when exposed to weather elements such as oxygen, water, etc. Good impact resistance: Depending on its thickness, plastic can bear a lot of weight and can take a lot of impact without deforming or breaking Good transparency and wear resistance: Plastic can be made transparent. This quality is essential for aesthetic purposes and hence can be used for various kinds of good-looking furniture. As furniture, its surface does not come off like hence it's durability.Low thermal conductivity: This means that it can bear heat without transmitting it easily. Ability to General formability, good coloring, low processing cost.4) Metal Jewellery
One of the best metals for jewelery is Tungsten. This is so because it is more durable and stronger than any other kind of material that can be used for jewelery purposes. It is about ten times harder than 18K gold and about four times harder than titanium. Other materials that can be used are:
titaniumstainless steel and cobalt5) Clay
In it's raw form, clay used for building might not be the best idea as it susceptible to water absorption and hence deformation which generally leads to a collapse of the structure. However, it becomes an excellent material of choice after it has been hardened into brick.
Brick is preferred in construction due to the following qualities:
hardnessHigh Compressive strength, Low Water AbsorptionFrost resistanceFireproofGreat Insulation6) Cotton is usually preferred as the material of choice for most kinds of clothing due to the following qualities:
Softness. The cotton plant is soft and fluffy and results in a fabric often retains that soft feel. Durability: Its molecular structure makes it able to last very long. Absorbency: it is able to absorb moisture/water. Hence making it more comfortable than synthetic materials High Dye Tolerance: Ability to hold dye well is an indespensable quality of a good fabric. You don't want to have a fabric whose colours are quick to fade. Breathability: This reduces is very important especially during summer or when the weather or environment is very hot.Cheers
The tar is roads that have quantities to make them deal with the construction. The liquid is a mix of asphalt and can be adhesive and waterproof.
The iron bars are used for securing the place and things. plastic furniture is used to make suitable furniture and is used for chemical stability etc. The metal jeweler is of titanium, cobalt and stainless steelLearn more about the following minerals.

A DNA sample is anyalyzed and you find that 22% is cytosine. How much thymine would be in the same cell?
Answer:
28% Thymine
Explanation:
DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%
Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.
Therefore; 22% C + 22% G = 44%
100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.

Use your knowledge of amino acids for energy metabolism to select the term that best completes each description. Glucose cannot be made when amino acids are converted to_________ . In the TCA cycle, some amino acids enter directly and, therefore, can continue in the cycle to generate energy and_______ . When is available, the body can use and glycerol to make some non-essential amino acids.
Answer:
Acetyl CoA; glucose
Explanation:
Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.
