A motorcycle weighs 2,009 newtons. The mass of the motorcycle is
kilograms. Use g = 9.8 N/kg for gravity.
Answer: 2009 N / 9.8 N/Kg = 205 Kg.
The mass of the motorcycle is approximately 205 kilograms.
Mass refers to the amount of matter in an object, and it remains constant regardless of the location (e.g., on Earth or in space).
Mass (kg) = Weight (N) / Acceleration due to gravity (N/kg)
Given that the weight of the motorcycle is 2,009 newtons and the acceleration due to gravity is 9.8 N/kg, we can calculate:
Mass (kg) = 2,009 N / 9.8 N/kg ≈ 205 kg
So, the mass of the motorcycle is approximately 205 kilograms. The weight of an object is the force with which it is pulled towards the Earth due to gravity. In this case, the motorcycle weighs 2,009 newtons, which means it experiences a force of 2,009 newtons due to the gravitational pull of the Earth.

Describe the energy changes occurring in the process in which ice melts to water
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.
What is a stationary location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust called?
Answer:
The continental plate is the location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust.
Explanation:
Volcanoes form at the edges of Earth’s tectonic plates. When the continental plate moves over the oceanic plate, it causes the oceanic plate to descend into the mantle where some of it melts, and the molten material moves into the mantle above the plate and causes the mantle to melt.
This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock, a volcano forms when the magma reaches the surface of the Earth at the continental plate.

Lynn Margulis developed the endosymbiont theory to explain the evolution of certain eukaryotic organelles, such as chloroplasts and mitochondria. According to this theory, which of these events occurred to an ancient prokaryotic cell?
Answer: Endosymbiosis theory suggests that eukaryotic cells emerge from prokaryotic cells.
Explanation:
Biologist Lynn Margulis was the first person who studied the endosymbiosis in 1960. According to him the chloroplasts and mitochondria have been originated from ancient bacteria which was free living. These organelles are found in eukaryotic cells. The chloroplasts are found in plant cells and they have a green pigment called as chlorophyll which helps in the process of photosynthesis by absorbing the sunlight energy. The mitochondria produce energy in the form of ATP by the biochemical oxidation of the food.

The main source of energy for both plants and animals is
A. water
B. fertilizer
C. glucose
D. carbon dioxide
Answer:
None of the above.
I'm pretty sure the Sun is the main source of energy.
Explanation:
Here is what I found:
Energy from the sun is the primary source of energy for the earth's ecosystem. The sun's energy is collected and processed by plants through photosynthesis and converted into food for animals. Without the sun, animals would not exist. Food is stored energy and essential elements like carbon, nitrogen and hydrogen.
The main source of energy for both plants and animals is glucose. Therefore, the correct option is option C.
The process of photosynthesis, which plants use to transform solar light energy into chemical energy, makes plants one of a kind. Here, plants use the energy from sunlight to change water and carbon dioxide into glucose, a simple sugar, and oxygen. Plants require glucose as a vital source of chemical energy in order to grow, reproduce, and perform other metabolic functions. The majority of life on Earth gets its energy mostly from this conversion of solar energy into chemical energy. On the other hand, sunlight cannot be used by animals as a direct source of energy. They instead rely on eating plants or other animals to meet their energy needs.
Therefore, the correct option is option C.

What types of substances do not dissolve easily in water?
Answer:
Many substances do not dissolve in water easilyand that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus it doesn't dissolve in water so easily.
That question got me thrown off
Answer:
Dominant
Explanation:
If both of the parents don't express the trait and the child does, then the pedigree is recessive. According to Mendel's law, the recessive trait will only show if there are two recessive alleles. If both of the parents of have the trait and their child does, that means that the parents are heterozygous.
If one of the parents have the trait and the child does or doesn't, then the pedigree is dominant.
Predict what will happen to interest rates and output if a stock market crash causes autonomous consumer expenditure to fall
Answer:
Lower interest rates.
Explanation:
if a stock market crashes, the interest rates will also be lowered because they have a direct relationship between stock market and interest rates. When the stock market performs very good, the interest rates will be higher while on the other hand, if a stock market crashes, the interest rates will be lower so we can conclude that the interest rates will be lower if stock market crashes.

2.Ocean systems:
The ocean is a global, interconnected system that has regions, or basins. Water and ocean life move between these basins and up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.
3.Proteins:
a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.
4.Saturated fat molecules:
Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)
5.Enzymes:
a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
6.Prokaryote:
a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

8.Hemoglobin:
a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a haem group.
9.Active Transport:

10.Phospholipids:
a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.
11.Facilitated diffusion:
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
