Answer:
hi
Explanation:
more objects and closer. We can also look at more distant points in space
When we look at the same portion of the sky with an even more powerful telescope that is in space then we will be able to see faraway objects. James Webb Space Telescope is the most powerful telescope.
What is Telescope?A telescope is a device used to observe the distant objects present in space by the emission, absorption, and reflection of electromagnetic radiations.

Levi decides to examine the effect of fertilizer on the growth of tomato plants. He chooses four plants for his experiment and applies varying amounts of fertilizer to the three of them. He does not apply fertilizer to one plant. Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13. Levi measures the height of all of his plants with a meter stick on Days 3, 6, 9, 12, and 15. He also makes sure to hold all experimental factors constant except for the fertilizer. Which statement describes what Levi did to prepare the control group in his experiment?
This question is incomplete because the options are missing; here are the options:
Which statement describes what Levi did to prepare the control group in his experiment?
A) Levi held all experimental factors constant except for fertilizer.
B) Levi did not apply any fertilizer to one of his plants.
C) Levi applied different amounts of fertilizer to three of his plants.
D) Levi measured his plants on five separate days.
The answer to this question is B. Levi did not apply any fertilizer to one of his plants.
Explanation:
In an experiment, the control group refers to the subject or subjects, in this case, the plants, that do not receive the treatment or variable tested by the researcher. This implies the control group for Levi is the plant with no fertilizer because this is the only plant that does not receive the treatment or fertilizer. Moreover, this acts as a control group because Levi can use this plant to determine if the growth of the other three plants is positively or negatively affected by the use of the fertilizer.

Why do we cut the celery stem under water
Answer:
Hey! Neko here!
Explanation:
That new empty space inside the leaves creates a low pressure, and like a drinking straw, this low pressure allows water below the leaf to travel up the stem. You’ll see the little tubes the water travels up when you cut the celery stem, and you can see the colour up in the leaves.
hope this helps ig! <3
We cut the celery stem under water to see the color change in the stem due to movement of water through the process of transpiration in the cell.
What is Celery stem?Celery stalks or stems are the petioles of the compound leaves. They are not the stems, in spite of the widespread misrepresentation in elementary school lesson plans only. They may also look like the stems to some people because they are thick and fleshy due to accumulation and have prominent veins which are running lengthwise through them.
When we cut the little tubes or celery stem under water travels up when and we can see the color up in the leaves. This process is called as transpiration. The new empty space which is present inside the leaves creates a low pressure, and just like a drinking straw, this low pressure allows the water below the leaf to travel up the stem.

Which is one piece of information that astronomers use to calculate the age of the universe?
dark energy
the age of rocks on Earth
the current motion of inner planets
patterns of background radiation
Answer:
d
Explanation:
The patterns of background radiation are information that astronomers use to calculate the age of the universe. Therefore, the correct statement is option D.
What is CMB radiation?Big Bang theory gives evidence about cosmic microwave background radiation that filled the early universe. The CMB radiation has uniformity in all directions, but it has slight temperature variations.
These variations are the result of small fluctuations in the density of matter in the early universe, which results in the formation of galaxies and other structures.
The patterns of these temperature variations are studied and astronomers learn about the properties of the early universe to make calculations about the age. They can use CMB radiation for estimation of the amount of time passed since the universe began expanding rapidly in the aftermath of the Big Bang.
Therefore, the patterns of background radiation provide very important information from which astronomers can calculate the age of the universe which is estimated to be about 13.8 billion years old.

Compare and contrast the random sampling and mark and recapture methods of
estimating population sizes. Describe a situation in which each method would
work best and why. Justify your answer.
Explanation:
jennjjj+ii8iiiiiiiuiiiiiiiu
Random sampling and mark and recapture methods are both commonly used to estimate population sizes, but they have different strengths and weaknesses.
What is random sampling?Random sampling involves selecting a random sample of individuals from a population and using that sample to make inferences about the population as a whole. This method is typically used when the population is large and diverse, and it is difficult to observe or count all individuals. Random sampling is also useful when the population is not easily marked or tagged, as it does not rely on the use of markers.
On the other hand, mark and recapture methods involve marking a subset of individuals in a population, then releasing them back into the population and later re-capturing them. The number of marked individuals that are recaptured is used to estimate the population size. This method is typically used when the population is small, and it is relatively easy to observe or count all individuals. Mark and recapture methods are also useful when the population is easily marked or tagged, such as with fish or birds.
A situation in which random sampling would work best is a study of the population of deer in a large forest. The forest is too vast to observe or count all individuals, so a random sample of deer would be selected and observed to estimate the population size.
On the other hand, a situation in which mark and recapture methods would work best is a study of the population of fish in a small lake.

C. They had no rights under the law.
D. All of the above
Answer: C.
Explanation:
Slaves did not have any rights
The statements about African slaves in America are true: they had no rights under the law, which is option C, as the African slaves in America were denied basic human rights and were treated as property rather than as human beings.
What are African slaves?The enslavement of Africans in America is a dark and painful chapter in the history of the United States. Beginning in the early 17th century, millions of Africans were forcibly brought to America and sold into slavery, where they were subjected to a lifetime of bondage, exploitation, and abuse. Under the system of slavery that existed in America, slaves had no legal rights and were not recognized as human beings under the law.
Hence, the statements about African slaves in America are true because they had no rights under the law, which is option C.

So Thank You
After pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.
What do you mean by Ecological succession?Ecological succession may be defined as the gradual and continuous replacement of one species by another over a specific period of time.
After the primary succession occurs, the pioneer species are evolved, and due to this, the process of ecological succession carries forward. These pioneer species are generally plants that performed photosynthesis.
Therefore, after pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.

The surface area and volume for four cells are given. Which combination of cell dimensions would be considered the MOST metabolically favorable?
A. cell 1: surface area 14 mm^2, volume 33 mm^3
B. cell 2: surface area 20 mm^2, volume 12 mm^3
C. cell 3: surface area 7 mm^2, volume 17 mm^3
D. cell 4: surface area 5 mm^2, volume 2 mm^3
Answer:
D
Explanation:
This is because a bad ratio would be one where the volume is larger than the surface area. Once a cell's volume is larger than the surface area, there's not enough surface area to process all the products coming in and waste coming out. Ideally, you'd want a surface area and volume to be as close to each other as possible in number, but you'd rather have the volume be less than the surface area.
