When does facilitated diffusion occur?
-When one liquid has a higher osmotic pressure than the other.
-When certain large molecules are unable to move through the membrane
without the help of channel proteins.
-When ATP is available to assist in moving molecules.
-When there's a strong membrane potential present, with the inside of the cell
being more negative than the outside of the cell.
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

In a 1973 essay with the same name, geneticist Theodosius Dobzhansky made famous the idea that nothing in biology makes sense except in the light of evolution. From a careful reading of The Serengeti Rules, one could also argue that nothing in biology makes sense except in the light of regulation. Do you agree or disagree with this claim
I agree with this claim because organisms interact with one another in an ecosystem, thereby regulating population sizes in the community.
The Serengeti Rules is a documentary film based on biologist Sean B. Carroll's book (2017). This book explains the balanced functioning of an ecosystem by exploring the discoveries of five pioneering scientists: Mary Power, Bob Paine, Tony Sinclair, John Terborgh, and Jim Estes.
The term 'Serengeti rules' is due to many of these rules were obtained by studying natural populations in the Serengeti National Park (Tanzania).
These rules are a set of simple ecological rules of nature that indicate how ecosystems work.
The Serengeti rules explain how organisms interact with one another in the ecosystem, thereby regulating population sizes in the community.
Some key concepts of the Serengeti rules are as follow: Keynote species is a type of species whose activities govern the wellbeing of other species in the ecosystem. A trophic cascade is a phenomenon by which species impact other species even when they do not directly interact with each other. Downgrading refers to cascading effect of the removal of a species at the top of a food web (e.g., predators)

An investigator wishes to use animals in an experiment that involves USDA pain category B, C, and D activities performed on the same animal. How should the animal be categorized
The animals used in an experiment that involves USDA pain category B, C, and D activities performed on the same animal should be categorized to USDA category D.
The USDA pain categories are used to categorize the level of pain an animal used in testing and research will be exposed to. The categories are as follows:
USDA B: the animal will not feel pain of any kindUSDA C: the animal will feel the occasional slight painUSDA D: Painful procedures that will be mitigated by pharmaceuticals.USDA E: Painful procedures that will not be mitigated.Category B states the animal will not feel pain. Animals in this category are often used for breeding, which is a natural process that does not cause animal distress or pain.
Animals in category C may feel the occasional slight pain which is allowed to subside naturally without the use of pharmaceuticals. This may include procedures such as
Drawing blood samplesInjectionsAnimals in category D are exposed to painful or stressful procedures and will receive anesthetics and other chemical agents to mitigate or completely relieve the pain, Whereas E category animals do not receive said assistance.
These categories follow a strict rule. Animals must be categorized according to the most painful procedure it will undergo, so because the experiment will use USDA B, C, and D procedures, the animals must be placed into USDA category D.

endocytosis.
Cells dispose of large waste molecules through a process called exocytosis.
Exocytosis is the process through which cells can eliminate wastes, which might be useless or toxic, to the extracellular space.
-------------------------------
The endocytosis and exocytosis process refers to molecules transport mediated by vesicles.
Exocytosis occurs from and into the cell and needs energy to happen because it is active transport.Exocytosis involves vesicles or vacuoles. Vesicles or vacuoles can carry substances destined for exportation or cellular wastes. Wastes may be large molecules that result useless for the cells or that might be toxic. During the exocytosis process1) excretion compounds of varying nature accumulate within the
vesicle
2) The vesicle migrates toward the cellular surface.
3) Once in the surface, the vesicle's membrane fuses with the cellular
membrane, and its content is expelled from the cell to the
extracellular space.
4) Vesicle membrane remains fused to the cell membrane until it is
reused during endocytosis events.

Distinguish between the 4 major modes of nutrition of prokaryotes and identify each modes energy source and carbon source as well as giving an example
The four major modes of nutrition in prokaryotes are photoautotrophic, chemoautotrophic, photoheterotrophic, and chemoheterotrophic. Their differences, energy source and carbon source are explained below:
WHAT ARE PROKARYOTES?
Prokaryotes are a group of organisms that do not have their genetic material enclosed in a membrane bound NUCLEUS. They include bacteria, archeae etc.METABOLISM IN PROKARYOTES:
All organisms, prokaryotes inclusive, need energy for their metabolic activities. They also need carbon. Hence, based on their carbon and energy source, prokaryotes can be:
Photoautotrophic: These are prokaryotic organisms that use carbon dioxide as their carbon source and light as their energy source. Example iscyanobacteria.
Chemoautotrophic: These are prokaryotic organisms that act on inorganic substances as energy source and use carbon dioxide as carbon source. Example is Nitrosomonas bacteria.Photoheterotrophic: These are prokaryotic organisms that use light as source of energy but obtain carbon from other organisms (organic sources). Examples are heliobacteria, sulfur bacteria.Chemoheterotrophic: These are prokaryotic organisms that act on inorganic substances as energy source but derive their carbon source from organic compounds (other organisms).Learn more: https://brainly.com/question/6103977

What is a major role that fungi play in ecosystems
Answer:
Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.
