Answer:
the correct answer is "C. 4"
Explanation:
The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control center of the cellular activities and is the storehouse of the cell’s DNA. By structure, the nucleus is dark, round, surrounded by a nuclear membrane.

Describe how an organism is classified currently hy Biologist
Answers
Answer: All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species.
Explanation:
Answer:
Organisms are classified by how similar they are to another organism.
They also find similarities with the DNA and examining physical features.
Explanation:
Modern biologists use DNA for this. Testing an organisms DNA can greatly help in classifying organisms.

C. The DNA transfers its information to RNA through an amino acid.
D. The DNA molecule unzips along weak hydrogen bonds.
Answers
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.
What is DNA replication?
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.

What happens during the first two stages of cellular respiration?
Answers
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

Some cells have multiple dendrites and/or axons. What advantages does this have for the nervous tissue?
Answers
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.
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.
Answers
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
