Which of the following best describes how energy is transferred in a food web?
A. A All energy is transferred to each level of a food web.
B. B Energy flows from producers to one or more levels of consumers.
C. C Consumers transfer their energy to producers.
D. D Decomposers get their energy directly from the sun.
Answers
Answer:
B.
Explanation:
Energy flows from producers to one or more levels of consumers. Think of it this way:
A banana tree grows in the forest.
A monkey eats the bananas off of the tree, it now consumes the energy provided by the banana.
(whatever animal kills monkeys) kills the money for food, they have now consumed the energy of the monkey, as well as the banana the monkey has eaten previously.
The web continues, and energy continues to be distributed to each level of consumer, all starting with a single producer.

The alignment of the sun, moon and earth during the eclipse.
The phase of the moon that is observable during the eclipse.
How the sun’s light is being blocked on the earth and the moon.
Type your answer on a Google doc and submit
Answers
Answer:
A lunar eclipse occurs when the Earth gets in the way of the sun and blocks sunlight from hitting the moon. This makes the moon have a reddish-orange tint to it. A full moon is visible during a lunar eclipse.
A solar eclipse happens when the moon gets in between the sun and the Earth, forming a crown like ring around the moon, which is from the sun. The moon itself might not be visible, due to the angle at which it sun is hitting it at.

Answers
If we assume that the question is referring to the probabilities of yellow and green seeds in a genetic cross between two heterozygous pea plants, the probabilities would be equal (1:1) according to Mendelian genetics. This means that there is an equal chance of a seed being yellow or green.
However, if the question is referring to probabilities in a different context, such as the proportion of yellow and green seeds in a bag of mixed seeds, or the probability of a yellow seed developing into a plant versus a green seed, the probabilities would be different and would depend on the specific situation.

Type several paragraphs describing how your models showed the effect of the rotation of Earth on day and night and the effect of Earth’s tilt on seasons and regional climates.
Please don't copy and paste from other websites, write everything in your own words.
Answers
Answer:
Explanation:
What Causes the Seasons?
The Short Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
It's all about Earth's tilt!
Many people believe that Earth is closer to the Sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the Sun in the winter.
Although this idea makes sense, it is incorrect.
It is true that Earth's orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the Sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the Sun and summer when it is farthest away! Compared with how far away the Sun is, this change in Earth's distance throughout the year does not make much difference to our weather.
There is a different reason for Earth's seasons.
Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom." Earth spins around this pole, making one complete turn each day. That is why we have day and night, and why every part of Earth's surface gets some of each.
Earth has seasons because its axis doesn't stand up straight.
But what caused Earth to tilt?
Cartoon of large object hitting Earth, knocking out big chunks of material that become the future Moon, and tilting the Earth's axis.
Long, long ago, when Earth was young, it is thought that something big hit Earth and knocked it off-kilter. So instead of rotating with its axis straight up and down, it leans over a bit.
By the way, that big thing that hit Earth is called Theia. It also blasted a big hole in the surface. That big hit sent a huge amount of dust and rubble into orbit. Most scientists think that that rubble, in time, became our Moon.
As Earth orbits the Sun, its tilted axis always points in the same direction. So, throughout the year, different parts of Earth get the Sun’s direct rays.
Earth's tilt is the reason for the seasons. View of Earth in relation to Sun during each of the four seasons. The hemisphere receiving the direct rays of the Sun has summer while the hemisphere tilted away from the Sun, thus getting its rays from more of an angle, has winter.
Sometimes it is the North Pole tilting toward the Sun (around June) and sometimes it is the South Pole tilting toward the Sun (around December).
It is summer in June in the Northern Hemisphere because the Sun's rays hit that part of Earth more directly than at any other time of the year. It is winter in December in the Northern Hemisphere, because that is when it is the South Pole's turn to be tilted toward the Sun.
Earth's lopsided orbit
Earth's perihelion (point closest to Sun) = 91,400,000 miles from Sun
Earth's aphelion (point farthest from Sun) = 94,500,000 miles from Sun
While that is a difference of over 3 million miles, relative to the entire distance, it isn’t much.
Drawing shows top-down view of Earth's orbit with Sun near center, showing distances from Sun at aphelion and perihelion.
And, believe it or not, aphelion (when Earth is farthest from the Sun) occurs in July, and perihelion (when we are closest) occurs in January. For those of us who live in the Northern Hemisphere where it's summer in July and winter in January, that seems backwards, doesn't it? That just goes to prove that Earth's distance from the Sun is not the cause of the seasons.
The rotation of Earth is the reason why we have day and night. Earth rotates on its axis, which is an imaginary line that runs from the North Pole to the South Pole. As Earth rotates, different parts of the planet are exposed to the Sun's light. When your part of the planet is facing the Sun, it's daytime. When your part of the planet is facing away from the Sun, it's nighttime. This rotation takes about 24 hours to complete, which is why we have a 24-hour day.
The tilt of Earth's axis is what causes the seasons. Earth's axis is tilted at an angle of about 23.5 degrees relative to its orbit around the Sun. This means that as Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun at different times of the year. When a part of the planet is tilted towards the Sun, it receives more direct sunlight and experiences warmer temperatures. When a part of the planet is tilted away from the Sun, it receives less direct sunlight and experiences cooler temperatures. This is why we have different seasons throughout the year.
Earth's tilt also affects regional climates. The amount of sunlight that a region receives depends on its latitude, or how far it is from the equator. Regions near the equator receive more direct sunlight throughout the year, so they tend to be warmer. Regions near the poles receive less direct sunlight, so they tend to be colder. However, Earth's tilt also affects the amount of sunlight that different regions receive throughout the year. For example, during the summer, the Northern Hemisphere is tilted towards the Sun, so it receives more direct sunlight. This causes warmer temperatures and longer days in the Northern Hemisphere. During the winter, the Northern Hemisphere is tilted away from the Sun, so it receives less direct sunlight. This causes cooler temperatures and shorter days in the Northern Hemisphere.

What are the functions of the three types of openings in the model: openings in villi, alveoli, and the cell membrane?
Answers
Answer: These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.
The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries.
In exocytosis, a cell releases substances into its environment. During exocytosis, vesicles that contain substances are moved to the cell membrane and fuse with it. This cell membrane function has three results: the total surface of the membrane increases, toxins or waste products are eliminated, and proteins become part of the plasma membrane.
Explanation:
thats all of the things for openings in villi the alveoli and the cell membrane

• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
