B) Businesses might invest in places that lack environmental regulations.
Explanation:
Certain gases in the atmosphere has the ability to trap the radiating heat from the earth and keep the atmosphere warm even during the night.These gases are called greenhouse gases.Carbon dioxide, methane etc are some example of green house gases. These gases are added to the atmosphere in large amounts due to burning of fossil fuel.Though green house gases are very important in maintaining the temperature of the Earth but if their percentage increases in the atmosphere then they may contribute to global warming.Global warming is a environmental havoc and is leading to global climate change and melting of ice caps.To manage this problem it is very necessary to reduce the increasing green house gases.To achieve this goal governments of various nation has formulated rules according to which, the industries that do not have efficient machinery to reduce consumption of fossil fuel and reduce green house gas emission are charged fines.But since these rules are not implemented in all places , the industries choose to establish business in those places where they are not forced to comply with strict environmental rules. So, there is a negative impact on the economy of the nation that have strict regulations to conserve environment.Answer: alt answer: there would be a financial incentive to protect the environment
Explanation:
Which organisms supply energy for all the others?
Answer:
Algae
Explanation:
Along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.
Answer:
That's easy It's plant's.
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
The process of _____________ is modeled in the plant cell diagrams seen here.
Answer:
The process of "Osmosis" is modeled in the plant cell diagrams seen here.
Explanation:
Osmosis is the natural gross migration of solvent particles into a zone of higher solute concentration via a selectively permeable membrane, in the path that seeks to balance the amounts of solvents on both the ends. Osmosis as biological membranes are semipermeable, is a critical mechanism in biological systems.
Such membranes are usually impenetrable to massive and polar molecules like polysaccharides, ions and proteins while being porous to hydrophobic or non-polar molecules like lipids and to small molecules as carbon dioxide, oxygen, nitric oxides and nitrogen.

Why does ethanol becomes cloudy/white when testing fat
Answer:
Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
The emulsion test for fats is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.

Differences between emulsion and solution https://brainly.com/question/6677364
Final answer:
Ethanol causes fats to form tiny droplets and become insoluble, resulting in a cloudy appearance due to the formation of an emulsion, which demonstrates the principle that like dissolves like.
Explanation:
The cloudiness or white appearance that occurs when ethanol is used in testing for fats is due to a physical process called emulsification. When ethanol is added to a solution that contains fats, such as in a food testing scenario, the fats can precipitate or separate from the solution because ethanol is less polar than water. Fats are nonpolar molecules, and when a polar solvent like water is mixed with a less polar solvent like ethanol, the nonpolar fats become insoluble and form tiny droplets, leading to a cloudy appearance. This is a demonstration of the principle that like dissolves like: polar solvents dissolve polar substances, and nonpolar solvents dissolve nonpolar substances. When nonpolar fats come into contact with ethanol, which does not dissolve them as well as water, they form an emulsion, which is a mixture of tiny droplets dispersed throughout the solvent.
This effect can also be observed in other scenarios. For example, when bile salts aid in the digestion of fats by breaking them down into smaller droplets, this increases the surface area for the enzyme lipase to work efficiently, which is essential for proper fat digestion inside the body.

When does the Mitosis-promoting factor (MPF) Cyclin concentration decline during a typical cell cycle in clam
eggs?
Answer:
During the division of cell nucleus, Mitosis-promoting factor (MPF) Cyclin concentration decline during a typical cell cycle in clam eggs
Explanation:
It is the absorption of cyclin that grounds the fluctuations in MPF absorption during the cell cycle. Synthesis of cyclin happens throughout interphase, instigating a build-up of cyclin. As additional cyclin is accessible to associate with Cdk1, the absorption of active MPF rises. MPF is made up of two proteins, a protein kinase (cdc2 in yeast) whose levels are constant throughout the cell cycle and a cyclin (cdc 13 in yeast) whose levels fluctuate during the cell cycle.

Why must the quality and quantity of DNA in cells remain the same from generation to generation?
Explanation:
As all organisms depend on their DNA to live, and any changes in the amount or quality of DNA. It will lead to mutations or death of the organism. If DNA is changed then it will be difficult for the chromosomes to match up and offspring will not be produced. The quality must be maintained. Otherwise other system in the body will not work properly.The quality and quantity of DNA in cells remain the same from generation to generation - to produce offspring and proteins for survival.
Any kind of change either quantity or quality of DNA causes abnormality in the production of proteins or viable produce as genetic information is not as it is supposed to be.
Such changes are called mutation or chromosome abnormality.DNA quality could be changed by the nucleotides being in the wrong order or extra or fewer bases.This results in the coded instructions being wrong and faulty proteins are made or control switches being changed.The body can't function as it should.Thus, for a healthy offspring and body, the quality and quantity of DNA in cells remain the same from generation to generation

Why isn’t blended inheritance a good explanation of heredity
The problem with blended inheritance is that it cannot account for certain observations.
What is heredity?Heredity, also known as inheritance or biological inheritance, is the passing on of traits from parents to their offspring; the offspring cells or organisms acquire the genetic information of their parents through asexual or sexual reproduction.
One of the most serious problems with the blending inheritance hypothesis is that offspring are frequently intermediate in some traits between their parents.
This can result in populations becoming highly uniform over generations, with no new variation emerging.
The issue with blended inheritance is that it cannot explain certain observations, such as traits that sometimes skip a generation or how two people of medium height could have a child who grew up to be much taller than them.
Thus, the blended inheritance is not a good explanation of heredity.

Discuss how the deletion of three nucleotides in a DNA sequence encoding a gene would affect the transcription and the resulting mRNA sequence.
Answer:
deletion is a type of mutation in the DNA which causes protein synthesis to fail.
Explanation:
the effect of this is to make a different protein instead of the correct one which will cause the organism to not have the proteins needed I. order to have the correct trait
The deletion of three nucleotides would result in the loss of one amino acid from the protein, potentially leading to a nonfunctional protein or altered protein function, while preserving the original reading frame.
The deletion of three nucleotides in a DNA sequence encoding a gene would not result in a frameshift mutation, as it is a multiple of three, which means the reading frame would remain unchanged. However, it would lead to the loss of a single amino acid in the corresponding protein because codons, which designate amino acids, are three-nucleotide sequences in mRNA. As a result, all the codons downstream of the deletion would still be read correctly, but the final protein would be missing an amino acid, which could affect the protein's structure and function, potentially leading to a nonfunctional protein or altered protein activity.
