Which of the following mutations will not result in a change to the amino acid sequence of a protein?
A)Frameshift mutation
B)Silent mutation
C)Neutral mutation
D)Nonsense mutation
Answer:
B)Silent mutation
Explanation:
A Silent Mutation is defined as a point mutation that does not change the amino acid. This occurs because more than one codon can code for the same amino acid. So while the protein was changed in the end there were no large-scale effects to the organism. This is why it is called a "silent" mutation because you cannot tell anything changes and there are no side effects.

Some cells have multiple dendrites and/or axons. What advantages does this have for the nervous tissue?
Answer:
It receives information from several cells.
Explanation:
The main advantage of cells having multiple dendrites and/or axons is that it receives information from several cells as compared to those cells which have one dendrite and receive information from only one cell. If neurons have hundreds or thousands of dendrites, so these dendrites allow the cell to receive information from thousands of other cells. So we can say that dendrites number plays a key role in nervous tissue.
What do the results tell us about the experiment? The bacteria from all 3 farms were almost 100% alive in the control samples, meaning that the experiment did not work. None of the bacteria from the 3 farms survived in the control samples. Because the bacteria in the control were almost 100% alive, we know that any deaths of bacteria in the other samples was because of the antibiotics.
Answer: D

“Because the bacteria in the control were almost 100% alive, we know that any deaths of bacteria in the other samples was because of the antibiotics.” Y’all should like my answer n give me the brain answer.
The results tell us that in the experiment the death of the bacteria in the other samples was because of the antibiotics, confirming that the bacteria from the farms are sensitive to antibiotics.
What does it mean that the antibiotic is sensitive to bacteria?If a bacterium undergoes the action of an antibiotic, it is said to be sensitive; if, on the contrary, the antibiotic has no effect on the bacterium, it is said to be resistant. Resistance can be natural or acquired (eg, by plasmid transfer or mutations).
With this information, we can conclude that the results tell us that in the experiment the death of the bacteria in the other samples was because of the antibiotics, confirming that the bacteria from the farms are sensitive to antibiotics.

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders. A population of wolves was introduced into Yellowstone National Park. The amount of disease in the deer population decreased. More grass and shrubs were planted in Yellowstone National Park.
Answer:
[tex]\boxed {\boxed {\sf B. \ A \ population \ of \ wolves \ was \ introduced \ to \ Yellowstone \ National \ Park }}[/tex]
Explanation:
Let's evaluate each choice. Remember we are looking for an event to decrease the genetic variation and population.
A. Yellowstone expanded its borders
If the park expanded, it's likely the population would increase. There would be more space and resources for the deer.B. A population of wolves was introduced
A wolf is a predator that preys on deer. If they were introduced, they would use the deer as a food source and decrease the population.B seems like a good answer, but let's check the others.
C. The amount of disease in the deer population decreased.
This would help the deer population. Less disease means fewer deaths and a greater population.D. More grass and shrubs were planted in Yellowstone
Deer are herbivores, so grass and shrubs would provide more food. This would keep the deer nourished and healthy, meaning a greater population.The best answer choice is B: A population of wolves was introduced into Yellowstone National Park

The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?
Mutations are always passed on to subsequent generations of the species
Mutations lead to genetic variation
Mutations are the cause of disease in the species
Mutations are not harmful when they occur in somatic cells of a species
Answer:
Your answer is B) Mutations lead to genetic variation.
Think of it like this, when rays were first starting to develop, they probably started with only one kind, stingless. Somewhere down the line, the genes of the rays started to mutate and eventually, there were stingrays and stingless rays. Now at this point there are predators that frequently feast upon the rays, so which of the two rays are more likely to defend themselves, and get away to live long enough to reproduce and pass on their genes? The stingrays! The mutation that may have occurred millions of years ago, has determined which organisms were more fit for a changing environment.
The survival of the species depends on the resources available and environmental conditions. The species or organisms capable to adapt to the surrounding have higher chances of reproduction and survival.
The correct answer is:
Option B: Mutations lead to genetic variation
The organisms adapting to the surrounding will undergo an alteration in their genetic sequence, known as mutations. The mutations are heritable and lead to genetic variation.
The mutation leads to genetic variation as:
It leads to the introduction of new alleles in the gene pool.Sexual reproduction and random mating also contribute to genetic variation. The mutations are heritable, and thus can cause an increase in the frequency of the mutated allele in the gene pool.
Thus, the correct answer is that mutation leads to genetic variation.
