What types of mutations are the most harmful
Answers
Answer:
Frameshift mutations
Explanation:
Frameshift mutations are generally much more serious and often more deadly than point mutations. Even though only a single nitrogen base is affected, as with point mutations, in this instance, the single base is either completely deleted or an extra one is inserted into the middle of the DNA sequence.

Charles Darwin not only proposed that species could change over time, but he also described a process by which these changes could occur. What was that process?
Answers
Answer:
Charles Darwin had a theory that states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
The theory of natural selection was proposed by Charles Darwin. Darwin postulated that species could change over time.
What is the theory of natural selection?The adaption by organism according to the surrounding environment is natural selection. It drives evolution.
Individuals in a population vary naturally. It means they are all different in some ways.
This variation means that some individuals have traits that suit better to the environment as compared than others.
This causes the species to change over time.
Thus, the process by which these changes take place is natural selection.

Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do mapping experiments become less accurate when the distances between genes become large? Interference is greater when the distance between genes is large. Multiple crossovers are more common. Crossover gametes become less common. Recombination occurs less frequently in long chromosomes.
Answers
Answer:
Multiple crossovers are more common.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.
Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.

Explanation:
<3 also the answer is variation im pretty sure
Any difference between individuals of the same species is called Variation.
Any difference between individuals of the same species is called variation. Variation can manifest in various ways, including differences in physical traits, genetic makeup, behavior, and physiological characteristics. It is a fundamental aspect of biological diversity and plays a crucial role in evolutionary processes.
Variation arises through various mechanisms, including genetic mutations, genetic recombination during sexual reproduction, and environmental influences. Genetic mutations can introduce new genetic variations into a population, while genetic recombination through sexual reproduction can shuffle existing genetic variations. Environmental factors, such as diet, climate, and exposure to different conditions, can also contribute to phenotypic variation.
Variation is essential for populations to adapt and evolve in response to changing environments. It provides the raw material for natural selection, a process by which certain variations are favored or selected for in a population, leading to evolutionary changes over time. Variation allows individuals to possess different traits and characteristics, some of which may confer advantages in specific environmental conditions, while others may be disadvantageous.
Understanding and studying variation is crucial in fields such as genetics, evolutionary biology, and ecology. It helps scientists understand the mechanisms driving genetic diversity, the processes of speciation and adaptation, and the dynamics of populations and ecosystems. Variation also has practical applications in fields such as agriculture, medicine, and conservation, where knowledge of genetic and phenotypic variation can inform breeding programs, medical treatments, and conservation strategies.

What describes gneiss?
Answers
Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.
Gneiss is a type of metamorphic rock that is formed by high pressure and temperature caused by the earth's surface.
What are metamorphic rocks?Metamorphic rocks are those rocks that are formed when other rocks are introduced under high temperatures and pressure that is exerted by the layers of the earth. There are three types of metamorphic rocks.
Since gneiss is a high-grade metamorphic rock, it has undergone more intense heat and pressure than schist. It is created through the transformation of sedimentary rock, such as granite.
Gneiss has distinctive foliation or alternate layers made of various minerals. This rock comes under the metamorphic regional type of rock.
Therefore, Gneiss rocks are those metamorphic rocks that are formed on convergent plate boundaries.

The diagram below shows a cell placed in a solution.
A cell is shown placed inside a beaker. It is labeled Cell. The solution inside the beaker is labeled 2% salt solution and the solution inside the cell is labeled 4% salt solution.
What will most likely happen to the cell?
It will expand as water moves out of it.
It will shrink as water moves out of it.
It will expand as water moves into it.
It will shrink as water moves into it.
Answers
The cell will shrink in size, losing water due to osmosis.
The most likely to happen to the cell is ; ( C ) It will expand as water moves into it
The movement of water in and out of a cell is based on osmosis .The cell membrane of the cell will regulate the movement of water molecules in and out of the cell. based on the solute concentration inside the cell and outside the cell.
When a cell is placed in a hypotonic solution ( i.e. a solution with a lower solute concentration as seen in the 2% salt solution ) the water molecules from the hypotonic solution will move into the cell which will cause the cell to be Turgid/expand over time.
Hence we can conclude that the most likely thing to happen to the cell is ; It will expand as water moves into it

Imagine sperm and egg cells have 46 chromosomes like other cells in the body. That
is they have 46 chromosomes when a sperm cells fertilizes an egg cell. Would that
affect the total number of chromosomes in their offspring or children? Tell why or why
not.
Answers
Answer:
When an egg and sperm having 46 chromosomes similar to the body cells, their fertilization produces offsprings or children with 92 chromosomes which are double number of chromosomes as compared to parent cell. So they are not similar to parents. As we know that fertilization is the process of fusion of gametes and paring up of chromosomes. The offsprings are different from their parents in having more chromosome sets.

How many different codons are possible in nucleic acids containing six different nucleotides if a codon consists of a consecutive sequence of three nucleotides
Answers
Answer:
216 codons
Explanation:
In the RNA molecule there are four types of nucleotide bases, i.e., Adenine, Uracil (Thymine in DNA), Guanine, and Cytosine. In consequence, the number of possible codons or combinations of nucleotide triplets is 64 (4³ = 64 codons). However, these 64 codons code for only 20 different amino acids because multiple codons can code for the same amino acid, it is for that reason that the genetic code is redundant. In this case, if the number of bases would be six (6) instead of four (4) bases, then the number of possible combinations of nucleotide triplets would be 216 codons (6³ = 216).
