Duplication in the gene encoding a protein Involved in vision has enabled humans to acquire trichromatic vision, which is the ability to
distinguish between red, green, and blue colors, which type of mutation is this?
OA.
somatic mutation
B.
Silent mutation
C. neutral mutation
D. harmful mutation
E. beneficial mutation
Reset
Next
Answer:
E
Explanation:
A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.
Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.
These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.
In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.

Using the data you just reviewed, create a scientific argument of one to two paragraphs that support or oppose the current flu vaccine recommendations.
The flu vaccine is essential in our society and should be encouraged and financed whenever necessary. That's because, as we know, the flu is a disease of rapid proliferation and that imposes risks to the lives of some people. The vaccine has the ability to reduce the risk of a person being infected with the flu virus by 50%, this percentage is essential for people who are more sensitive to this virus such as the elderly, pregnant women and people with respiratory problems.
In addition, it is important that the manufacture and distribution of this vaccine is always financed, because the flu virus is a very changeable circle that is constantly changing and needs to be combated annually.
Answer:
Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.
Explanation:
Flu vaccinations reduce the risk of flu illness by over 50%. This makes this process extremely important and fundamental for all human beings as they not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people, especially children and older adults who possess a greater risk of developing flu complications.
The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell. However, if a person has not been vaccinated, the virus will attack the healthy cells because there is an absence of antibodies that prevent this process.

The statement “force equals mass times acceleration (F=ma)” is Newton’s second law of motion. Why is this a law rather than a theory?
A-It states, rather than explains, the relationship between the variables.
B- .It cannot be proven, whereas a theory can be proven.
C-.It may be revised if new information shows that the relationship has changed.
D- It was classified as a law because it is related to other similar discoveries.
Answer: it’s A
Explanation:
Newton’s second law of motion is a law rather than a theory because: A. It states, rather than explains, the relationship between the variables.
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
[tex]Force = mass[/tex] × [tex]acceleration[/tex]
This ultimately implies that, Newton's Second Law of Motion is a law because rather than explain, it states the relationship between the three (3) variables;
Force.Acceleration.Mass.In conclusion, a law can be proven whereas a theory may be revised in the event that a new information shows that there is a change in relationship between the variables.

if two species from the same kingdom met would they attack each other
Answer:
It is possible.
Explanation:
Let's take the Animalia Kingdom for example. You know that animals are prey and predator in the environment, and that there are food chains. Animals (carnivores or omnivores) do eat other animals to sustain their lives. It is entirely possible and plausible that 2 pieces from the same kingdom could attack each other.

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.
Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.
STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.

Which of Charles Darwin’s main points is depicted in the image? Organisms within a population compete with each other to survive. Over time, beneficial variations will be passed on to future generations. More offspring are produced than can be supported by an environment. All organisms within a population have an equal chance for survival.
Answer:
A). Organisms within a population compete with each other to survive.
Explanation:
Charles Darwin in his evolution theory proposed that the organisms of all species emerge and develop via the 'natural selection' of tiny, inherited discrepancies and these disparities enhance the individual's ability to contest and compete with each other in order to survive and reproduce to continue their existence. This led to the emergence of the phrase 'survival of the fittest' which suggests that in this competition of 'natural selection', only the fittest will survive. Thus, option A is the correct answer.
Answer: a

Where does the river deposit the most sediment?
O A. Where the water moves the fastest
B. Where the water has no kinetic energy
C. Where the water moves the slowest
D. Where the water has the greatest kinetic energy
Answer:C
Explanation:River deposit the most sediment along the inside bank of the river bend,this is where water flows the slowest.So,when water moves the slowest deposition occurs while when water moves the fastest erosion occurs.
The river deposit the most sediments where the water moves the slowest. The correct option is c.
What are sediments?Strong substances known as sediments settle at the bottom of a fluid. This might also be thought of as a naturally occurring substance that is disintegrated and moved by wind or water.
As a result of its shape, an irregularly shaped sediment would move at the slowest rate possible. The act of deposition is the settling of sediments within designated deposition basins.
The river deposits the most sediment along the inside bank of the river bend, this is where water flows the slowest. So, when water moves the slowest deposition occurs while when water moves the fastest erosion occurs.
Therefore, the correct option is c. Where the water moves the slowest.
