Answer:
C
Explanation:
Because osmosis(B) this is where water moves from a high concentration to a low concentration across a partially permiable membrane( No energy required). Whereas in diffusion (a) this is the net movement of particles from a region of a high concentration to a region of a low concentration. This stops when the region is evenly spread. (No energy is required)
The cell transport which takes place in food coloring, potato slice is concentration gradient. This type of cell transport does not need energy. Thus, the correct option is C.
What is Cell transport?
Cell transport is the transport of molecules through the cell membrane. Transport of substances through the membrane takes place through osmosis and diffusion.
The diffusion of substances can be active or passive on the basis of requirement of energy. The passive mode of transport does not require energy as the movement of substances occurs down the concentration gradient from high concentration to low concentration. Whereas, in active transport energy is required in the form of ATP as the transport occurs against the concentration gradient from low concentration to high concentration.
Therefore, the correct option is C.

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.
Please help with answer 3 :)
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.

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.

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).

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.

which molecules determine the tissue specificity of hormones?
Answer:
Steroids. Which molecules determine the tissue specificity of hormones? Receptors. Hormones bind to receptors on target cells and trigger a cellular response.
Explanation:
The tissue specificity of hormones is determined by hormone receptors. Proteins called hormone receptors are found on the cell surface. A hormone's binding to its receptor starts a chain of actions that eventually affects the activity of the cell.
For various hormones, different cells have various receptors. This implies that a hormone can only attach to cells that also contain such receptors. The tissue specificity of hormones is a result of this.
For instance, the insulin hormone attaches to receptors on cells in the muscle, fat, and liver tissues. These receptors bind to insulin, which sets off a series of processes that eventually result in the absorption of glucose from the circulation by these cells.
