Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.
Answer:
The correct answer is -
1) point mutation
2) deletion
3) inversion
4) frameshift mutation.
Explanation:
Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.
Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.
When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.
If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.
Why couldn't yeast use both sugar and artificial sweetener for cell respiration?
Yeast couldn't use both sugar and artificial sweetener for cell respiration because of the low calorie content of artificial sweetener.
What is artificial sweetener?Chemicals called artificial sweetening agents are used to sweeten food. They do not, however, provide our bodies with extra calories.Which one will have better yield?The sugars will have better yield because natural sugars like sucrose have more calories than artificial sugars.This increased energy will allow the yeast to metabolize faster and hence more carbon-dioxide is released.What is cellular respiration?"Cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a compound called as adenosine triphosphate (ATP)."

Why would a normally aquatic or marine species adapt to the supralittoral fringe where they have to deal with desiccation and temperature stress?
Answer:
In order to survive.
Explanation:
A normally aquatic species adapt to the supralittoral fringe in order to survive in that environment. Supralittoral zone also referred to the area on coastlines and estuaries, that is regularly splashed, but not submerged by ocean water. This environment is different for the marine organisms that causes adverse effect on the marine organisms but these marine animals has the ability to adapt that environment by using certain mechanism in order to survive and easily reproduce in that environment.
Helicobacter pylori, the bacterium responsible for gastric ulcers, can survive in the stomach (where the pH is as low as 1.5) in part because it synthesizes large amounts of the enzyme urease. (a) Write the reaction for urea hydrolysis by urease. (b) Explain why this reaction could help establish a more hospitable environment for H. pylori, which tolerates acid but prefers to grow at near-neutral pH.
Answer:
a) (NH₂)₂CO + H₂O ---> CO₂ + 2NH₃
b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a base by accepting the hydrogen ions present in the acidic environment of the stomach. This reactions serves to neutralize stomach acid in order to create a suitable pH environment that the bacterium requires to survive and colonize.
Explanation:
a) Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The equation of the reaction is shown below:
(NH₂)₂CO + H₂O ---> CO₂ + 2NH₃
b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a base by accepting the hydrogen ions present in the acidic environment of the stomach. This reactions serves to neutralize stomach acid in order to create a suitable pH environment that the bacterium requires to survive and colonize.
The reaction of ammonia with hygrogen ions from HCl is shown below:
NH₃⁺ + H⁺ ----> NH₄⁺
Therefore, the continuous activity of the enzyme urease, helps to establish a more hospitable environment for Helicobacter pylori

Which of the following statements about the flow of energy in nature is not true?
A. A large amount of energy in food is needed for bodily function
B. A major portion of the energy from food is used to keep our bodies warm
Only a small portion of the energy from food is used to keep our bodies warm or for other bodily functions. Most of it is lost as heat or through other processes.
When answering questions on Brainly, it is important to always be factually accurate, professional, and friendly. It is also important to be concise and avoid providing extraneous details, while also taking care to address all parts of the question.
Typos and irrelevant information should not be ignored. In the case of the provided question, the answer is option B: A major portion of the energy from food is used to keep our bodies warm. This is not true in the context of the flow of energy in nature.
The flow of energy in nature involves a constant transfer of energy from one organism to another in an ecosystem. Energy enters an ecosystem through primary producers like plants, who convert sunlight into food through photosynthesis.
This energy is then transferred to herbivores, who are then eaten by carnivores. As energy flows through the food chain, only a small amount of energy is transferred from one trophic level to the next.
The majority of the energy is lost through respiration, heat loss, and other metabolic processes.
