b. activation of the parasympathetic autonomic nervous system by the new experience.
c. hypoxia caused by insufficient blood hemoglobin concentration to supply oxygen for exercise at the low oxygen pressure found at high altitudes.
d. depressed core body temperature (hypothermia) caused by exposure to cold temperatures at high altitudes.
Answer:
The correct answer is - option C.
Explanation:
Skiing generally happens on higher altitudes such as mountains. It is known that there is less oxygen is available at higher altitudes. There is low oxygen pressure at such height.
The prolonged increase in heart and breathing rate is due to less oxygen available for the cells. This condition is known as hypoxia caused by insufficient blood hemoglobin to supply oxygen for physical activities at higher altitudes.
How do the vacuoles and cytoplasm contribute to maintaining homeostasis in a cell?
Answer:
Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity
what three phases of the cell cycle are considered interphase
Answer:
The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.
Explanation:
The three phases of the cell cycle that are considered interphase include G1, S phase and G2.
The cell cycle can be divided into the interphase and mitotic (M) phases.The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.

When the Volume of Liquid was 60 mL what was its mass?
Answer:
60 grams or 0.060000 kg
Explanation:
To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column
Answer:
IgG molecule, p53 molecule, actin molecule, histone molecule
Explanation:
In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.
In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

How are humans impacting biodiversity in ecosystems around the world? Provide two examples to support your claim.
Answer:
as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.
Human activities have affected in Biodiversity in the ecosystems negatively and such activities include : i) Indiscriminate hunting/fishing ii) Improper waste disposal
Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.
When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.
Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing and Improper waste disposal

important in the digestion of animals (leafcutter ants for one)
can cause disease in plants (dutch elm disease)
can cause disease in animals (candidiasis for one)
Explanation:
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.
