Answer:
Answer: A common example is decantation of oil and vinegar. When a mixture of the two liquids is allowed to settle, the oil will float on top of the water so the two components may be separated. Kerosene and water can also be separated using decantation.

Place the four images from the cell cycle in the correct chronological order.
four magnified cells
A. Image A, image D, image B, image C
B. Image C, image D, image B, image A
C. Image C, image B, image A, image D
D. Image B, image C, image D, image A
Correct Answer: C. Image C, image B, image A, image D
Explanation: Image C shows the cell in interphase. The cell's DNA is in the form of chromatin. Image B shows the cell in prophase. The chromosomes have thickened and can be seen individually. Outside the nucleus, spindle fiber is beginning to form between the centrioles. Image A shows the cell in metaphase. The chromosomes have lined up along the equator of the cell and are attached to spindle fibers at their centromere. Image D shows the cell in anaphase. The individual chromatids have been drawn apart to opposite poles of the cell. This is just before the cell begins to split into two identical cells.

During which phase does the cell actually separate into two individual daughter cells?
A. Prophase
B. Cytokinesis
C. Interphase
D. Metaphase
Correct Answer: B. Cytokinesis
Explanation: Cytokinesis is the phase during which the cytoplasm of the cell divides and the cell actually separates into two cells. The term cytokinesis actually means cutting (kinesis) of the cytoplasm.

If your were to examine a sample of 1000 cells, in which of the phases listed below would you expect to find most of the cells?
A. Interphase
B. Metaphase
C. Anaphase
D. Telophase
Correct Answer: A. Interphase
Explanation: Most cells spend about 90% of their life cycle in interphase. Therefore, if you were to examine a random sample of cells, most of them would be found to be in interphase.

Upon examining a sample consisting of 100 cells, you find the following distribution of cell phases. If you know that the cell cycle for this type of cell takes two hours, how long, on average, does the cell spend in prophase?
table of cell phase data
A. 8 minutes
B. 16 minutes
C. 22 minutes
D. 30 minutes
Correct Answer: D. 30 minutes
Explanation: There are 100 cells and 25 of them, or 1/4 of the entire sample, are in prophase. From this you can conclude that these cells spend 1/4 of their cell cycle in prophase. The length of the cell cycle for these cells is 2 hours, or 120 minutes. Therefore, the cells spend about 30 minutes in prophase.
You answered this question correctly!
Results Summary
In what part of the cell cycle does the DNA make a copy of itself?
A. Interphase
B. Prophase
C. Telophase
D. Cytokinesis
Correct Answer: A. Interphase
Explanation: The replication of DNA occurs during interphase. Arguably, the replication of DNA is the most important step in the cell cycle, as it allows the cell to pass on a full copy of its DNA to each daughter cell. If this step did not occur, each daughter cell would only receive a portion of the parent DNA.

The cell cycle in the correct chronological order is the cell during interphase (image C), Prophase (image B), metaphase (image A), and Anaphase (image D) (Option C).
The cell cycle can be divided into an interphase and a mitotic (M) phase, in which the cell divides.The interphase is the phase where the cell replicates its genetic material (DNA) and grows to prepare for its division.The interphase divides into a Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.The M phase can, in turn, be divided into these sequential steps:

How many variant gametes (in meiosis of a single cell) can be produced if we allow for crossing over on the longer of the two chromosomes? How many variants could be produced over time by a population of these cells undergoing meiosis and then fertilization?
What two characteristics of life are described in the following statement? “A human begins life as a single cell, whereas an adult is made up of trillions of cells.”
The two characteristics of life that are described in the statements are reproduction and development.
What is life?Life is a quality that distinguishes types of matter. The living matter from the non-living matter is distinguished by the quality of life. Living persons live, grow and reproduce.
Reproduction is a biological process by which an organism from another organism, this organism, grows from a single cell to a multicell and this grows up of cells from tissues and tissues from organs, and organ form an organism.
Development is when a small organism grows into a large organism. Living organisms grow and develop, and with time their degeneration occurs. So, with reproduction, development happens in living organisms.
Thus, the two characteristics are reproduction and development.

amino acid can be split into two groups. Name and Descibe the two groups
the 2 groups are essential acids and non essential acids. basically essential amino acids have to be made from what somebody eats (your diet). non essential amino acids are made in the body.
Amino acids can be divided into two groups, and these groups are essential and non-essential amino acids.
What are amino acids?Amino acids are micro molecules that are made up of amine and carboxylic groups. A side R group chain is also present. It is the basic unit of protein. Many amino acids join together to form protein. There is a total of 20 amino acids.
There are two types of amino acids full stop non-essential amino acids are those assets that a living body can produce, so they cannot be taken from outside food. Essential amino acids cannot be produced by the body, so they are taken in the form of food.
Therefore, essential amino acids and non-essential amino acids are the two categories into which amino acids can be categorized.

Compare between energy yield in aerobic and anaerobic respiration. Support your answer with reference
Aerobic respiration has more energy yield than anaerobic respiration.
Cellular respiration refers to the process that has to do with breaking down food molecules like glucose which is then converted into ATP.
The cellular respiration in the presence of oxygen is referred to as aerobic respiration. On the other hand, cellular respiration in the absence of oxygen is referred to as anaerobic respiration.
It should be noted that aerobic respiration is more energy-efficient than anaerobic respiration. While aerobic processes produce about 38 ATP per glucose, anaerobic processes produce about 2 ATP per glucose.
In conclusion, aerobic respiration has more energy yield than anaerobic respiration.

Green plants need chlorophyll and sunlight to make food is not the answer because it also needs CO2.Green plants get carbon dioxide from the roots is not the answer because they get CO2 from the leaves through stomata.All plants take in water and minerals from the roots is not the answer.All plants do not have chlorophyll because Cuscuta is a parasitic plant that does not have chlorophyll.I hope this answer deserves a like : )
(Please help!) A scientist is studying the population of Cape Fox over four generations to determine if the population is in Hardy-Weinberg Equilibrium.
No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.
Yes, the population is in Hardy-Weinberg Equilibrium because the fourth generation reverts back to the initial population levels.
No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of dominant and recessive alleles are not equal.
Yes, the population is in Hardy-Weinberg Equilibrium because the recessive allele is always greater than the dominant allele.
Answer:
Explanation:
1 There are no mutations in the DNA of the population.
2 The recessive phenotype in this population may serve as an adaptation in this environment.
3 No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.
4 The brown color is an adaptation that is being selected by the environment.
5 The number of individuals displaying each phenotype in both the current generation and the offspring.
No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.
What is Hardy-weinberg Equation?The hardy-Weinberg equation is used to calculate the genetic variation in a population, which is in equilibrium.
The equation is p2 + 2pq + q2 = 1.
The given data has changed in the frequency of allele, so there is no equilibrium.
But, Hardy-Weinberg Equation tells the genetic variation in equilibrium.
Thus, the correct option is A, No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.
