Answer:
k = (P^2)/(A^3)
Explanation:
Step 1: Flip the equation.
[tex]kA^3 = P^2[/tex]Step 2: Divide both sides by A^3.
[tex]\frac{kA^3}{A^3} = \frac{P^2}{A^3}[/tex] [tex]k = \frac{P^2}{A^3}[/tex]Therefore, the answer is [tex]k = \frac{P^2}{A^3}[/tex].

Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

A biology class in Virginia conducted a survey of the plant species found on their school grounds. They found several plants that they didn’t recognize. What resources would be most helpful to the class in identifying the plants and determining if they were introduced as exotic species?
This is a multiple choice
1). Virginia newspaper and science journals
2). Biology textbooks and the encyclopedia
3). Virginia native species checklists and plant identification keys
Can someone tell me the answer and explain how you got it please?
Answer:
c
Explanation:
I would say C because then you can identify if it was introduced as an exotic species if it is not native. Then you will also be able to identify what type of plant it is with the key.
Pick one sentence or paragraph from the article, and explain how it supports the idea that science is an evolving discipline that depends on repeated testing.
Answer:
From Edmentum:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” The paragraph explains that this new dinosaur gives some evidence that the dinosaurs in South America were structurally different from dinosaurs in other areas of the world. According to the paragraph, scientists will need to find and examine more dinosaur fossils from this region before they can support this claim. The claim supports the statement that science requires repeated testing.
Reworded:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” Paleontologists used to think all dinosaurs were similar all around the world, but the structure of a specific species of dinosaur made them second guess themselves. It seemed that the dinosaurs in South America were evolving different structures and functions than dinosaurs from other continents. The claim supports that the statement needs more testing.
Explanation:
Answer:According to Novas, "Paleontologists once believed that dinosaurs were identical on all continents, at least during the Jurassic era. The combination of traits on C. diegosuarezi currently casts some doubt on that theory. The structure of a particular species of dinosaur caused paleontologists to reevaluate their previous belief that all dinosaurs were globally identical. It appeared that the architecture and functions of South American dinosaurs were evolving differently from those of dinosaurs from other continents. The claim argues in favor of additional testing for the assertion.

When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

Wjy is the increase in atmospheric carbon dioxide dangerous?
Answer:
The gas inhibits the escape of heat from Earth’s
Explanation:
This is the main cause of global warming. They cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.
But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.
Answer:
If you increase carbon dioxide, the temperature can go up causing our earth to have global warming problems.

A block of aluminum has a mass of 40.5 grams. If the density of aluminum is 2.7 g/mL, what is the
volume of this block?
Answer: 15 mL
Explanation:
Volume = Mass ÷ Density
= 40.5 g ÷ 2.7 g/mL
= 15 mL
∴ the volume of the block of aluminum is 15 mL.
