Answer:
The genetic material's inheritability shows how that the DNA of all creatures, both living and dead, can be traced back to a single point, which is our common ancestral origin of life.
Explanation:
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
Explanation: The ones who are doing this on Gizmos the answer is 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.

Fermentation does not produce ATP. Why is fermentation such an important process in cells
Answer:
In humans we go through Lactic Acid Fermination
Explanation:
It is important because after glycolysis we have the elctron carrier NAD+ reduced to NADH and we cant continue glycolysis until we have NADH back to NAD+ so all lactic acid fermintation does it removed the electron and allow glycolysis to continue. It should be noted that fermintation occurs when there is no oxygen / not enough to continue cellular respiration so we rely on glycolysis to produce very little ATP while oxygen is replenished,
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
Answer:
answer B is correct I just took the test!

Explanation:
Sara is watching television when the power goes out. When she walks to the kitchen to get a candle, she knocks over a chair. She lights a match and holds it to the wick of the candle. She uses the light from the candle to find her way to the chair, which she picks up and sits in. Which of the events was a chemical change? *
Answer:
She lights a match and holds it to the wick of the candle.
Explanation:
Chemical change produces the required products of reactants by an irreversible reaction. For there to be a chemical change, a chemical reaction between reactants must occur.
Lighting of a match is a chemical change in which the friction between the match box and the gun powder on the stick produces a flame. This reaction produces a product by an irreversible process. After the flame burns out the wick of the candle, it can not be reversed.

What are the uses of the energy provided by ATP in the living cells?
Answer:
ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached.
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 is gene expression?Gene expression is the procedure by which genetic information is utilized in the biosynthetic pathways of a functional gene product.
This aids in allowing it to produce end products such as protein or non-coding RNA as well as, as a result, affect a phenotype.
Several factors affect gene expression, along with molecules inside the cell, mutations that cause dominant negative effects.
It also cause haploinsufficiency, signaling molecules from neighboring cells and the surrounding environment, and epistasis. Several molecules within the cell influence gene expression.
The following process accurately describes gene expression: DNA is transcribed into RNA, which is then translated into protein.
Thus, the correct option is A.

B. A single-stranded RNA molecule forms.
C. The DNA transfers its information to RNA through an amino acid.
D. The DNA molecule unzips along weak hydrogen bonds.
Answer:
D
Explanation:
The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule. This is carried out by an enzyme, called helicase which breaks the hydrogen bonds? holding the complementary bases of DNA together
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.
