Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

What is complementary base pairing? Explain why complementary base pairing is necessary to maintain the double helix shape of the DNA molecule.
Answers
Answer:
A complimentary base pairing is how adenine can only bond with thymine and how guanine and cytosine through hydrogen bonding. It is necessary to maintain the double helix shape. Because it is opposite, that is why the DNA is that shape. It is anti parallel due to the Complementary base pairing.
Adenine can only bond with thymine and guanine with cytosine via hydrogen bonding. It's important to keep the double helix shape. Complementary base pairing causes antiparallelism.
Why complementary base pairing is necessary?Base pairs linked to a sugar-phosphate backbone form the double helix structure of DNA.
DNA is composed of four nitrogenous bases: thymine, adenine, guanine, and cytosine. Guanine and cytosine are linked by three hydrogen bonds, while adenine and thymine are linked by just two. The term for this is complimentary base pairing.
Complementary base pairing is critical for the formation of the helical helix of DNA because it permits the base pairs to be organized in the most energetically favorable manner. It is also essential for replication since it permits semiconservative replication.

B. Male ligers cannot produce offspring with female ligers.
C. Male and female tigers cannot grow as large as ligers.
D. Female ligers can produce offspring with male lions or tigers.
Answers
Answer:
A.
Explanation:
Because it makes sense that you NEED a Male Lion and a Female Tiger to produce a Liger. That's the only possible way and I'm 100% sure this answer is correct :)
Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.

how are humidity and precipitation related
Answers
Explanation:
Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher humidity in cool air than warm air. A related parameter is the dew point.
I hope it's helpful!
Answer:
Temperatures are not independent of precipitation and a related factor, humidity. When humidity levels are low, most commonly during winter and spring, temperature has greater daily swings. When humidity levels are relatively high, such as during the summer monsoon, temperatures often fluctuate less dramatically from day to night.

By adding tape to his BAAD, Cramwood increased its mass and increased

What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.
