3. Linnaeus and other early scientists classified organisms based on visible traits. Today, scientists generally use
cladograms based on DNA and other evolutionary evidence to classify organisms. Why have most scientists
changed their method of classification?
a. Cladograms are relatively small and the information in them is easy to manage.
b. Cladograms can compare more animals at one time than traditional classification methods.
C. DNA evidence supports the idea that species that look similar are always more closely related than species
that do not
d. DNA evidence often shows that species that s hare characteristics but look different can be more closely
related than species that look alike.

Compare between energy yield in aerobic and anaerobic respiration. Support your answer with reference

Answers

Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

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.

Explain the link between insufficient sleep and obesity

Answers

Answer:

It is no secret that a good night's sleep makes you feel better. Not only does sleep give your body time to rest and recharge, it may also be crucial to your brain's ability to learn and remember.

During sleep, while your body rests, your brain is busy processing information from the day and forming memories. If you are sleep deprived, you are at risk of developing a number of serious health problems, such as hypertension, obesity, and diabetes, and your ability to learn and retain new information may be impaired.

This may not be news to anyone who has pulled an all-nighter cramming for a test only to find the facts and figures they knew at 2 a.m. could not be recalled the next day. Without adequate sleep, your brain becomes foggy, your judgment poor, and your fine motor skills hindered.

(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.

Answers

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.

What is the difference between the dependent variable and
the independent variable in an experiment?

Answers

Answer:

A dependent variable is a variable whose value depends upon some other variable where as, an independent variable is a variable whose value doesn't depend upon any other variable.

Explanation:

For example:

Let us take an expression y=3x+1, where x has some given values { let's assume x lies between 0 to 100}

so we can see that the value of y is depending upon the value of x ,as for every different value of x we will get a different value of y. So we can say that y is a dependent variable.

On the other hand, x doesn't depend on y as its values are already mentioned or specified so it's an independent variable.

Answer:

A dependent variable is a variable whose value depends upon some other variable where as, an independent variable is a variable whose value doesn't depend upon any other variable.

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.

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.

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.

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:

ProphaseMetaphaseAnaphaseTelophase

In conclusion, 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).
