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.
The mantle ( semisolid molten magma ) experiences an upward pattern of magma circulation and this is caused by mantle convection currents.
Hence we can conclude that the general pattern of magma circulation in the mantle is Upwards and downwards towards the crust.

Describe the difference between the melting points of ethene and poly (ethene)
Answer: Poly(ethene) has a higher melting point than ethene. The reason can be seen in the explanation below.
Explanation:
Ethene is one of the most important alkene hydrocarbons which is one of the main products obtained during the cracking of the gas oil fraction of petroleum.
Polymerization is a process whereby two or more simple molecules are linked to form a much larger molecule usually called polymers. Poly( ethene) is formed when ethene and it's derivatives undergoes polymerization reaction. Therefore poly( ethene) is a polymer of ethene.
To describe the reason why there is higher melting point in poly (ethene) than ethene is that poly( ethene) consists of very long chain carbon atoms which are held together by a strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules like ethene.

Answer:
ribosomes
Explanation:
The tomato plant and the oxalis plant both achieve a maximum CO2 utilization rate. Why do you think higher and higher light intensities do not cause an over increasing of CO2 use?
Answer: Higher and higher light intensities do not cause an over increasing of CO2 use because of other RATE LIMITING FACTORS that affects it's utilisation.
Explanation:
The tomatoe and the oxalis plants are examples of flowering plants which manufactures it's food through the process of photosynthesis. The conditions necessary for photosynthesis to occur leading to the production of starch and oxygen includes:
--> presence of sunlight
--> presence of carbondioxide
--> presence of chlorophyll and
--> presence of water.
The above conditions are factors that can affect the rate of photosynthesis occuring in a plant. Increasing a particular factor can lead to another factor being limiting. An example is the effect of increased light intensity on carbondioxide utilisation. Increase in light intensity could lead to excess evaporation of water from the plant. This will interfere with the light stage of photosynthesis by affecting photolysis of water. If this occurs, carbondioxide won't be reduced to form sugar in the dark stage of photosynthesis since there won't be hydrogen provided by the co-enzyme NADP (Nicotinamide adenine dinucleotide phosphate).
What are the possible results of speciation?
Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Explanation:
The process where the organism with the best traits survives and passes on its DNA is:
Evolution
Adaptation
Natural Selection
Variation
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.

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.
