Answer:
1. It involves making observations, formulating a hypothesis, and conducting scientific experiments. Scientific inquiry starts with an observation followed by the formulation of a question about what has been observed.
2. A hypothesis is a tentative answer to a scientific question. A testable hypothesis is a hypothesis that can be proved or disproved as a result of testing, data collection, or experience. Only testable hypotheses can be used to conceive and perform an experiment using the scientific method.
3. An experimental control is used in scientific experiments to minimize the effect of variables which are not the interest of the study. The control can be an object, population, or any other variable which a scientist would like to “control.”

Even though Earth's atmosphere is around 75% Nitrogen gas,
explain why animals (and most plants) are unable to use that
nitrogen as is:
I need help please!!!
Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
1. Noah is completing volunteer hours at a local aquarium (Seaworld) during
his summer break. While at seaworld he discovered that during the hot
summer months the plankton in the outdoor aquarium would grow in size
much quicker than any other seasons. That next summer he volunteered
again, but noticed they moved the phytoplankton aquarium indoors and
now they only have access to sunlight for 3 hours. What inferences can
you make about the growth of plankton during Noah's second year of
volunteering?
Answer:
2e
Explanation:fdsas
The inferences which a person can make about the growth of plankton during Noah's second year of volunteering is:
They would not grow as they had in the first yearAccording to the given question, we are asked to make an inference on what we believe would be the possible growth of the phytoplankton during the second year of Noah volunteering.
As a result of this, we can see that the inference which we can make about Noah's second year of volunteering is that the phytoplankton would not grow as much as they did in the first year.
This is because of the reduced time which the planktons would receive sunlight compared to the first year.

A topographic map. Smith Road is near index contour line with number 450. Shelton Road is near index contour line with number 450. Imperial Drive is in an area with index contour lines with number 500. Thurgood Avenue is in an area with index contour lines numbered 450.
Which street travels through the region with the steepest slopes?
Smith Road
Shelton Road
Imperial Drive
Thurgood Avenue
Answer:
Thurgood Ave because it travels through 450 to 500 which is the biggest on the map.
Explanation:
Also I took the Unit Test on Edge 2020.
As can be seen in the provided graphic, Imperial Drive passes through a location with some of the sharpest hills, hence option C is correct.
What is a topographic map?The contour lines on the map show that the imperial drive is located in the eastern part of the image and extends farther to the northeast.
The contour lines show where the region is geographically, and Imperial Drive's lines may be observed to imply a larger number than the other three streets.
Additionally, it is evident that Imperial Drive has several twists, which causes the street to seem steeper. The imperial drive has an indicator of around 550, while the other three streets have an indication of about 500.
Therefore, Imperial Drive passes through a location with some of the sharpest hills, hence option C is correct.

Based on the trilobite fossil, what can you infer about the rock layers in these location? Layer a is 500 million years old. Layer a is the same age at each location. Layer a us made of indigenous rock. Layer a is younger than layer b.
Answer: Layer a is 500 million years old.
Explanation:
Trilobite is a member of the group of extinct arthropods found as fossils and they can be identified by the three-lobed as well as three segmented forms. These were the marine animals. These were appeared initially in the Cambrian Period. They used to live 542 million years ago so the fossils can be estimated to be aged of 500 above years old. These animals used to dominate in the sea area.

Why would a killer whale require more energy than the wolf?
Explanation:
Because the orca swims faster, to catch it's prey, unlike the wolf, the orca hunts alone, which means, they do all the energy instead of the wolf, which distribute their energy among the others. Meaning the orca needs more energy, because the wolf, hunts in a pack. You understand? (I learned this from wild kratts lm_o XD)
A killer whale would require more energy than a wolf because it is a much larger animal that has a higher metabolic rate and energy demands.
Why whales require more energy?Killer whales, which are among the most dangerous predators in the ocean, need a lot of energy to keep their body mass the same, keep up with their high activity levels, and keep their body temperature stable when they are swimming in frigid waters. In order to hunt and successfully capture their prey, which frequently requires employing complex hunting methods that call for coordination and cooperation among members of their pod, these animals need substantial amounts of energy resources.
Wolves, on the other hand, are terrestrial predators that are smaller in size and generally have lower energy demands than killer whales do because their prey is typically smaller and easier to catch than the large marine mammals that killer whales eat. Wolves live in areas where there is less competition for resources, such as food.

Explanations of the function of each component in the cell membrane
Answer:
Structure of Plasma Membranes
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries.
The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The membrane also maintains the cell potential.
In short, if the cell is represented by a castle, the plasma membrane is the wall that provides structure for the buildings inside the wall, regulates which people leave and enter the castle, and conveys messages to and from neighboring castles. Just as a hole in the wall can be a disaster for the castle, a rupture in the plasma membrane causes the cell to lyse and die.

Your friend is on the cross country running team. They tell you they need to "carbo-load" ahead of their big race in a couple days as they want to store extra carbohydrates in their muscles.
1. Identify what macromolecule should they eat more of over the next couple of days? Identify that molecule's function.
2. Identify what food from the selection should they eat. (Hint: There is more than one correct answer)
3. Explain how you know that food has the macromolecule they need. (Think about what test will you use to support your statement)
HELPPPPPPP
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of some options
1. There are four major macromolecules found in nature; Carbohydrates, proteins, lipids and nucleic acid. The macromolecule that assists with the production of energy for immediate energy and glycogen storage (which is the storage of "energy" in the muscle) is carbohydrates.
2. The foods that should be selected here are food that are rich in carbohydrate. Examples of such food include Rice, cassava, yam and plantain.
3. To test for the presence of carbohydrate in the food sources chosen in (2) above, iodine test can be used. The choice of iodine test is because the food sources mentioned above contains complex carbohydrates. Few drops of a solution of iodine should be added to a sample of the food, if the colour of the iodine on the sample turns blue black, then that confirms the presence of complex carbohydrates in the food.
