Energy is transferred between organisms in food webs from producers to consumers.
The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Which statement correctly describes measuring with a graduated cylinder?
The liquid in the cylinder usually forms a convex meniscus.
Measurement is taken at the bottom of the meniscus.
Measurement is taken at the top of the meniscus.
The liquid in the cylinder can only be water.
Answers
Answer:
measurement is taken at the bottom of the meniscus.
Explanation:
the first answer is not correct since water forms a convex meniscus while Mercury forms cone meniscus just as indicated in the photographs above.
I agree with the second point since we were taught that the Reading should always be taken at the bottom of the meniscus.not on top of the meniscus.
the liquid in the cylinder cannot only be water. we can either put water, Mercury or any other liquid,but not specifically water.
Answer:
measurement is taken at the bottom of the meniscus.

HELP 20 PTS BRAINLIEST Create a comic strip that describes how a colony of bacterial cells being treated with an
antibiotic becomes resistant. Use the space below, or draw on your own sheet of paper. Include
either narration or speech/thought bubbles in your comic, and correctly include each of the
following terms: mutation, random, beneficial, evolve.
Answers
Panel 1: A colony of bacterial cells is growing in a petri dish.
Panel 2: A scientist adds an antibiotic to the dish.
Panel 3: The antibiotic kills some of the bacterial cells, but some survive.
Panel 4: The surviving cells reproduce, creating a new colony of resistant bacteria.
Narrator: Over time, the colony of bacterial cells has become resistant to the antibiotic.
Answer:
[Image description: A series of four-panel comic strips showing a colony of bacterial cells being treated with an antibiotic and becoming resistant over time.]
Panel 1:
[Caption]: The colony of bacteria is thriving in their environment.
[Image]: A group of bacterial cells are shown living in their environment with a happy expression on their faces.
Panel 2:
[Caption]: An antibiotic is introduced to the environment.
[Image]: A bottle labeled "Antibiotic" is shown being poured into the environment. The bacterial cells look surprised.
Bacterial Cell 1: "What's happening?!"
Bacterial Cell 2: "I don't know, but it doesn't look good!"
Panel 3:
[Caption]: The antibiotic kills most of the bacterial cells, but a few survive due to a random mutation that makes them resistant.
[Image]: The environment is shown with dead and dying bacterial cells lying on the ground. A few cells that are still alive are shown with a "X-Men" style logo over their heads, indicating they have mutated and become resistant.
Bacterial Cell 1: "Why aren't we dead like the others?"
Bacterial Cell 2: "I don't know, but it's like we're immune!"
Panel 4:
[Caption]: The resistant bacteria cells multiply and evolve, becoming stronger and more resistant.
[Image]: The environment is shown again, but this time, the resistant bacterial cells have multiplied and are shown with a "Superman" style logo over their heads, indicating they are stronger and more resistant.
Bacterial Cell 1: "Wow, we're stronger than ever!"
Bacterial Cell 2: "That antibiotic has nothing on us now!"
[Caption]: And that's how a colony of bacterial cells becomes resistant to an antibiotic

The picture shows an elliptical orbit with a planet on it. At the center of the orbit there is a circular sun. The label below the picture reads 'Formation of planet'
The picture shows an elliptical disc. At the center of the disc there is a circular sun. The label below the picture reads 'Fusion of gas and dust at the center to form the Sun'
Answers
Answer:
B.) rotation of cloud of gas and dust
Explanation:
According to Nebular theory, the sun and the planets were formed from the Solar Nebula. Initially a fragment of the molecular cloud of dust and gases collapsed under its own weight. This contracted portion starts to rotate until a high enough temperature and pressure causes the nuclear fusion reaction in the core to start and form the Sun. The planets were formed from rest of the part of the cloud.

1. is the first blank increases or decreases?
2. Is the second blank increases or decreases?
Answers
2. Increases
As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
what is star luminosity ?luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
Answers
Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.
Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.
Buried rocks melt deep within the mantle.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.
