The formulas that will be used are:

Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.

Gravitational force = GMm /r²
Centripetal force = mv²/r

Equating,
GMm/r² = mv²/r
v² = GM/r

The first scenario will use the formula v² = GM/r


Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.

v = 2rπ/t

Hm, I thought it would be 0%. . . Since the male (hetero) would be Bb and the female (homo dominant) would be BB, So the dominant gene would be dominant over all of the recessive genes. (BB, BB, BB, Bb).

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell pr
Alexeev081 [22]

Answer:

This question lacks options, the options are:

A. chemical energy -> kinetic energy

B. kinetic energy -> solar energy

C. solar energy -> chemical energy

D. kinetic energy -> nuclear energy

The correct answer is A.

Explanation:

All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.

This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.

Note that, kinetic energy is the energy due to motion in the Chipmunk.

What evidence has allowed scientists to conclude that the common ancestor of modern chimps and humans lived around 7 million yea
tatyana61 [14]

Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.

<h3>What is DNA?</h3>

All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.

The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.

The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.
