What is the debate among scientists on how new species form?

Answers

Answer:

read explanation

Step-by-step explanation:

Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate.

Final answer:

Scientists have different models explaining how new species form. This includes 'Gradual Speciation' and 'Punctuated Equilibrium' models which describe the pace of speciation. Additionally, they consider 'allopatric' and 'sympatric' speciation describing the mechanisms of speciation.

Explanation:

The debate among scientists on how new species form revolves around different models and patterns observed in nature. Two main models of speciation that scientists explore are the 'Gradual Speciation' model and the 'Punctuated Equilibrium' model.

Gradual Speciation proposes that species evolve slowly over an extended period due to slight genetic changes from generation to generation. On the other hand, Punctuated Equilibrium suggests that species remain unchanged for many generations and then undergo rapid changes to form new species in a relatively short period.

Another aspect of the debate involves the mechanisms of speciation, including 'allopatric' and 'sympatric' speciation. Allopatric speciation involves a geographical separation of populations from a parent species and subsequent evolution, while Sympatric speciation is speciation that occurs within a parent species while in one location.

Is the product of a fraction that is less than one and any whole number less than or greater than the while number?Explain your thinking.

Answers

Less. A whole number times 1/2 is half of the whole number, a whole number times 1/4 is a fourth of the whole number. 6x1/2=3, 6x1/4=1.5 :)

A CD usually sells for $13.00. If the CD is 20% off, and sales tax is 6%, what is the total price of the CD, including tax?A.$10.34
B.$11.02
C.$11.13
D.$11.18

Answers

If it is 20% off, we multiply the decimal form of 20%(0.2) to 13. 0.2 x 13 equals 2.6, and we subtract 13 by this to get 10.4. 10.4 is the price of the CD after the 20% off, so now we need to figure out the price after tax. Since tax is 6%, we can multiply the decimal form of it(0.06) to the discounted price. 10.4 x 0.06 equals 0.624, and 10.4 + 0.624 equals 11.024. So the total price of the CD including the discount and tax is $11.024.

:)
First, find 20% of 13:

\sf0.20*13=2.6

Subtract this from the price:

\sf13-2.6=10.4

Now find 6% of this:

\sf0.06*10.4=0.624

Now add this to the discounted price:

\sf10.4+0.624=11.024

So the price is approximately $11.02

Hannah is having a new house built. The following is an initial blueprint of her new living room and entryway.

The perimeter of the scale drawing is ______centimeters.

If the scale is 1 centimeter = 5 feet, the perimeter of Hannah's actual living room and entryway would be ______feet.

Numerically, the value of the actual perimeter of Hannah's living room and entryway would be _______times the value of the perimeter of the scale drawing.

Based on these results, if the scale is 1 centimeter = k feet, the perimeter of Hannah's actual living room and entryway would be ______feet.


Thank you!

Answers

For the first blank where it asks for the perimeter, the perimeter is all the outside sides of a shape added up. So, 6 + 1 + 2 + 4 + 4 + 5 = 22.

For the second blank, you just multiply the entire perimeter by 5, so, 22 times 5=110.

For the third blank, it is basically the same as the previous question. The answer is 5.

For the fourth blank, it is the same perimeter as the first blank, but instead of centimeters, it is in k. So, 22k.

Hope this helped! :)

Answer:The first one is 22 The second one is 110 The third one is 5 The fourth one 22k

Step-by-step explanation:

dd all the sides of the scale drawing.

So, the perimeter of the scale drawing is 22 centimeters.

If the scale is 1 centimeter = 5 feet, then the dimensions of the actual living room and entryway are 20 feet, 25 feet, 30 feet, 5 feet, 10 feet, and 20 feet. Now, add all the sides of the actual living room and entryway.

So, the perimeter of Hannah's actual living room and entryway would be 110 feet.

To find how many times larger the actual perimeter is than the scale drawing perimeter numerically, divide the numerical value of the actual perimeter by the numerical value of the scale drawing perimeter.

So, the value of the actual perimeter of Hannah's living room and entryway would be 5 times the value of the perimeter of the scale drawing.

Notice that in the scale of 1 to 5, the perimeter of the actual shape is 5 times the perimeter of the scale drawing. So, in a scale of 1 to k, the perimeter of the actual shape would be k times the perimeter of the scale drawing. Therefore, for the scale of 1 centimeter = k feet, the perimeter of Hannah's actual living room would be 22k feet.
