Explanation:
A ) Fossil fuels provide cheaper energy
MARK AS BRAINLIST IF IT IS USEFUL .
Fossil fuels are a non-renewable resource that takes years to form. They are the source of large energy production and provide cost-efficient cheaper energy. Thus, option A is correct.
What are fossil fuels?Fossil fuels are the dead remains that got converted into sediments and over millions of years produced the fuels used to drive energy. They are produced from deposition of the organic matter and are widely used resources for energy.
They are present in the crust of the earth and are a cheaper form of energy than wind and geothermal energy. They are found in the form of coal, petrol, diesel, and other natural gases. They are produced from decaying organic matter.
These fuels are less costly than the alternative form of energy, however, are the reason for increased temperature and climate change. They have added to the greenhouse gases and are major pollutants.
Therefore, option A. fossil fuels are cheaper.

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.

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

Explanation:
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)

The best describes the bond that can’t be broken is B. Between the anomeric carbon of a sugar and an OH (or N) of another molecule
Glycosidic bonds are a class of covalent bonds that joins a carbohydrate molecule to another group.
A polysaccharide (where poly means 'many') is a long chain of monosaccharides linked by glycosidic bonds.
Glycosidic bonds are formed between the hemiacetal group of a saccharide and the hydroxyl group (OH) of another compound (e.g., alcohol).

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.

Most physical characteristics are inherited. Scientists have discovered several genes that contribute to human fatness, particularly genes that regulate the production of specific ____________ , such as ____________ , which stimulates hunger, and ____________ , which reduces hunger.
Answer:
hormones; ghrelin; leptin.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific physical characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A gene can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Over the years, scientists have discovered several genes that are known to contribute to human fatness (body weight), especially genes that are saddled with the responsibility of regulating the production of specific hormones, such as ghrelin, which stimulates hunger, and leptin, which reduces hunger.
