Answer:
Im pretty sure everything but C is correct...
Water is a compound whose molecule is made up of two elements, namely hydrogen and oxygen. Because of the different atoms, the charge throughout is not the same. Thus, the correct option is C.
The molecule of water contains three atoms in total, two of hydrogen and one of oxygen. It is represented chemically as H₂O.
Because of the difference in the atoms, there is also a charge that is formed due to the difference in the electronegativity of oxygen and hydrogen atoms.
As a result. the electrons are more pulled towards oxygen andthus, oxygen has a more negative charge and hydrogen has a more positive charge.
Thus, the charge is not distributed throughout evenly. Thus, the correct option is C.

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.

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.
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.

Question:
In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye. Which statement is true regarding the light wave as it travels through the different media?
Answer:
D. The light wave will bounce back into the air when it moves into the water because it gets refracted from the bug to the fish's eye.
Just A Few Notes From The Internet:
The light waves will travel straight from the bug to the fishes' eye because that is the most direct path. The light waves will travel straight from the bug to the fishes' eye because there is no change in medium. The light waves will bounce off the surface of the water and the fish will see it.

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.

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.

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.
