5. A(n) ______, such as a salamander, is an organism that gains body heat primarily by absorbing it from the environment.

In DNA, Adenine pairs up with thymine and guanine pairs with cytosine. If adenine makes up 40% of the bases in DNA, then what pe

ycow [4]

A=T= 40%....so together this is 80% of the DNA.

That leaves 20% to be C+G...so each is 10%. A is the answer.

Which feature of a membrane describes whether molecules can cross the

anyanavicka [17]

Answer:

A

Explanation:

If it's a permeable membrane then it will allow certain molecules in. If it's impermeable then it won't allow molecules in. Therefore it is the deciding feature of whether something can go into the membrane.

C. At what height would the pomegranate have the same potential energy as the melon? (1 point)

zvonat [6]

Answer:

Given a set of assumptions which are given below, the height at which the pomegranate will have the same potential energy as the melon is 39.19 meters.

Explanation:

Gravitational Potential Energy refers to the acquired innate energy of an object due to its elevation above the surface of the earth.

This energy is the result of gravitational pull or force acting on the object.

In other to determine at what height a pomegranate and a watermelon will have the same potential energy we need to know the other factors in play.

Gravitational Potential Energy (Ep)= mgh

Where m = Mass (kg)

g = gravitational field strength (N/kg)

h = height (m)

Ep = gravitational potential energy ( j )

Let us assume that the

An average pomegranate weighs about 0.255146Kg

An average melon weighs about 10Kg
g is always constant at 9.8 N/kg

Note that melons weight much more than pomegranates.

So, let's calculate for the Ep of the melon at the height of 1 meter

Ep = 10 x 9.8 X 1 = 98j

Using the above assumptions, we do a goal seek using Microsoft Excel. Please see the attached image.

Calculation shows that the Height (h/Meters) at which the Ep of both veggies become equal is 39.19m

This can be verified by inserting the figure and multiplying it. It can also be calculated as follows:

That is

Ep = 98j

m = 0.255146kg

g= 9.8kg

h= ?

98= 0.255146 x 9.8 x h

98 = 2.5004308h (we divide both sides by 2.5004308 to make h the subject matter)

h = 98 / 2.5004308

h = 39.1932462198

Which is approximately 39.19

Connect photosynthesis and respiration be sure to include in your discussion the function of mitochondria and chloroplasts

Vadim26 [7]

Photosynthesis makes a sugar for the plant, in order for photosynthesis to occur the plant needs carbon dioxide and water, and with the use of the sunlight it produces oxygen and glucose. For respiration you need glucose and oxygen which produces carbon dioxide, water and ATP(energy) for the cell. I hope this helps, I only know the first half of the question.

Feathers in birds appear to have first evolved for insulation but later conveyed a new advantage in helping create light aerodyn

Karolina [17]

Answer:

<h2>Exaptation</h2>

Explanation:

Exaptation is the process by which the features acquire those functions for which they were not originally selected or adapted. Feather is an example of exaptation, it has appeared in various fossils of the flightless ancestors of modern birds, it later became important for flying, Once they molded for flying it adapted for that function, It is found in both behavior and anatomy.
