Which of the following observations would support the claim that a particular mutation is neutral?
a
The frequency of the mutation in a population, once it first appears, tends to increase over time.
b
In a given population, individuals that possess this mutation have a greater rate of reproduction.
c
The mutation is higher in populations of organisms that produce fewer offspring and have shorter life spans.
d
The frequency of the mutation goes up and down with no observable effect on the health of a population.

What is an insertion mutation?
Answer:
An insertion mutation is when by accident extra DNA bases are added to the DNA. The insertion changes drastically the nature of the proteins produced by the DNA chain. The addition of extra DNA disrupts the reading frame of DNA resulting in the wrong amino acids being produced.
Explanation:
What is the difference between a substrate and an active site?
Answer:
a reactant in a chemical reaction is called a substrate when acted upon by enzyme. an active site is the part of an enzyme to which substrates bind and where a reaction is catalyzed. :)

Explanation:
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

would you expect there to be fewer snails or fewer bass in this ecosystem?
Answer:
di ko lam
Explanation:
di ko alam
Answer:
there would be fewer snails because the bass are not being eaten by anything so their population would grow, the snails on the other hand they are eaten by many other oganisms so their population wouldn't grow as fast as the bass would.
Explanation:
Plz plz plz pls help u will save my life
Answer:
B) increase in number
Explanation:
This is called natural selection. Basically, the organism that has mutated in a way that helps it survive best will pass on that mutation.
Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in your own words
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
Explanation:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

happens to this chemical in the presence of starch?
Explanation:
12.In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange.
13.Monosaccharides: The Sweet Ones
Monosaccharides: The Sweet OnesThey are the building blocks (monomers) for the synthesis of polymers or complex carbohydrates, as will be discussed further in this section. Monosaccharides are classified based on the number of carbons in the molecule.

If a doctor suspects Down syndrome in a developing fetus, what should be observe via karyotype analysis?
Answer:
There will be an extra chromosome on the 21st chromosome.
Explanation:
Down syndrome (aka trisomy 21) is a genetic chromosome 21 disorder causing developmental and intellectual delays. Karyotypes show the chromosomes so the 21st chromosome will be abnormal.

Explain what incomplete dominance is
Answer:
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism ’s resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance. One example is shown in roses.
