Describe how the changing species concept has affected classification systems

Answers

Answer 1
Answer: The changing species concept has affected classification systems by distinguishing one species from the other. It has the effect of making to appear that species and their distinctive attributes are external and fixed. The reason for that because o the evolutionary process they have undergone.

Smallest to largest my options are bacteria, nerve cell, red blood cells , and virus ​

Answers

Viruses, bacteria, rbc, nerve cell

Final answer:

The items in order from smallest to largest are: virus, bacteria, red blood cells, and nerve cell.

Explanation:

In order from smallest to largest, the items you listed can be arranged as follows: virus, bacteria, red blood cells, and nerve cell. A virus is the smallest out of these options, typically ranging around 20 - 400 nanometers. Bacteria are slightly larger, generally falling within the 1 - 10 micrometers range in size. Red blood cells are typically about 6-8 micrometers in diameter, which is larger than most bacteria. Finally, the nerve cell, also known as a neuron, is the largest of the group. The body of a neuron can range from 4 - 100 micrometers in diameter, and their axons, or long projections, can be up to one meter long.

Find the arc length of a circle that has a 6-inch radius and a central angle that is 65 degrees. Use 3.14 for π and round your answer to the nearest hundredth. Choose the answer from the choices provided. A. 0.65 inch
B. 1.13 inches
C. 6.80 inches
D. 390.01 inches

Answers

The arc length is calculated by using the equation below:

Arc length = 2πr ( C/360)

where r is the radius and C is the central angle.

Arc length = 2π(6) ( 65/360)
Arc length = 6.81 inches

Therefore, the correct answer is option C.

The arc length of circle is 6.81. thus option C is correct.

How is the radius used to compute arc length?

The arc length formula for a circle is times the radius of a circle. When is in radian, the arc length formula in radians is arc length = r. Arc Length = (/180) r, where r is the angle in degrees and L is the length of an arc.

The following equation is used to compute the arc length:

Where r is the radius and C is the central angle, arc length = 2r (C/360).

2(6) (65/360) arc length

The length of the arc is 6.81 inches.

As a result, option C is the proper response.

Can someone please rewrite this and make it sound good. PLEASE HELP VERY DESPERATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!The scientist obtains either the same gene or the same protein from each of the three organisms. Then the sequence of the DNA or protein is determined and the three sequences are lined up and compared to see how well they match. The greater the match between any pair of sequences, the closer the linkage is between the two organisms. The greater the difference in sequence, the more distant the relationship. Once it has been determined how close or distant the relationship is between all of the organisms, a diagram is created that resembles a branched tree. Organisms are placed on closely linked branches if they have a strong math in sequence, while organisms with poorly matching sequences are placed on branches much farther away from one another.

Answers

The scientist gather the same DNA or Proteins from all 3 organisms, which will help determine the sequencing of the Protein or DNA. They then line them up and compare each DNA or Protein to measure how well they match. Depending on how well they match they can then determine how closely related or un-closely related they are. When observing the DNA or Protein the more closer related they Appear to be the more Un- Related they Actually are. When Scientist Know how closely related they are they may then make a Tree Diagram showing the resemblance. When looking at the branch the more closely related they are the, the closer they will appear on the Tree Diagrams Branches. Then the less related they are the farther they are placed from each other on a branch of the Tree Diagram.

 now that you know the bacteria in each tank drag the tanks to put them in the correct order

Answers

Answer:

1st ammonia nitrifying

2nd nitrite nitrifying

3rd denitrifying

Explanation:

Final answer:

The task involves arranging tanks according to the bacteria present in them, which could be determined by their type or concentration. Knowledge of different bacteria and their characteristics or quantities may be required.

Explanation:

The question is related to sorting tanks based on the bacteria present in them. This might involve consideration of different bacterial species, or possibly the number or concentration of bacteria in each tank. For example, if one tank has E.coli bacteria, another one has Staphylococcus, and a third one has Salmonella, you would need to arrange the tanks based on certain given criteria, perhaps related to the properties of these specific bacterial species.

On the other hand, if the task is about counting bacteria or organizing based on their concentration, microscopy might be used to estimate the bacteria in a sample from each tank. Given numbers could then be used to arrange the tanks in ascending or descending order.
