Explanation:
The flow of energy moves in a circle through a food chain. The energy moves from the grass to the grasshopper. Next, the transfer of energy passes from the snake to the hawk. Finally, the fungi help by breaking down the hawk when it dies, and returns the energy to the grass. Where does the energy that is transferred through this chain originate? A) fungi B) grass C) grasshopper D) sun
Answer:
i think it is B grass
Explanation:
Grass obtains energy through the use of photosynthesis. Chlorophyll absorbs sunlight and uses its energy to convert carbon dioxide and water into carbohydrates.

D. A group with 50 DD parrots, 25 Dd parrots, and 25 dd parrots.
Answer:
B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.
A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.
What do you mean by Hardy-Weinberg equilibrium?The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

What is the difference between a supermassive black hole and an ordinary black hole
Answer:
A supermassive black hole is a perfectly ordinary black hole that happens to be really, really big.
The majority of galaxies, including our own milky way galaxy, contain supermassive black holes, supermassive black holes that are millions to billions of times more massive than our sun.
What is a supermassive black hole?Supermassive black holes and ordinary black holes with masses ranging from millions to billions of solar masses are very hefty, to the mass of more than around the sun.
In further detail, stellar-mass black holes have masses that range from around 50 times our sun's mass to about 3 times our sun's mass.
Therefore, in comparison, supermassive black holes are millions to billions of times more massive than our sun and have a mass of more than around 50,000 times that of our sun.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
Answer:
conclusion
Explanation:
hope this helps
Answer:
1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.
5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.

1. A. What is diffusion?
1. B. Use diffusion to
explain what happens when you drop a
sugar cube into a mug of hot tea.
2. A. What is osmosis?
2. B. Describe how water molecules
move through the cell membrane during
osmosis.
Answer:
Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.
The three conditions that encourage the presence of marine life in the ocean are proximity to land, water depth and.
Answer:
Exposure to sunlight.
Explanation:
Sunlight is important condition necessary for the presence of Marine life in ocean. This is because sunlight provide energy for ocean current and wind waves. When this energy is converted to heat, it a layer of warm water which is present at the ocean surface which support most Marine life. Sunlight produce light energy which is needed for Marine life like algae to photosynthesized in addition with carbondioxide and water in order to to produce necessary for survival for most Marine life.
Q1.16 Suppose an entire village from a very wet region of Africa escaped mosquitoes by moving to an unpopulated area in a dry region. How would the move change people's fitness?
Answer:
Explanation below.
Explanation:
The movement will help the people to exercise more.
It should be understood that the presence of mosquitoes and the situation of the region as a wet region will not allow people to do much exercise, but their movement to the dry region will allow them to do more exercise than that of the wet region.
People and increase is the correct answer to the given fill in the blanks.
Population and area:People's relative fitness would improve on average because agricultural crops would be harder to manage in dry places, resulting in a lack of nutrients in the population, leading to disease.
The urban population grows while the rural population shrinks as a result of population migrations. This lowers worker productivity in rural regions, causing them to go dormant, and increasing the strain of urban expansion on them.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
