I think it is Displacement over Elapsed Time that is the rate of change in velocity.
The answer is true because, the earth was a supercontinent named Pangea, which in turn the ocean was super big then and this was 250 million years ago. You are very welcome.
Answer:
The correct answer would be Y-chromosome analysis.
Y-chromosome analysis is technique used to search the parental line of a boy on his father's side.
Gender of a person is determined by 
chromosome in humans. XX is present in females and XY is present in males.
Mother always passes X chromosome to her progeny but father passes both X and Y chromosomes. If X is passed from the father then the offspring will be a girl and if Y is passed from the father then the offspring will be the son.
The sons (F₂) of this son (F₁) will also bear the same Y chromosome as that of grand father (P).
Thus, Y chromosome always passes from father to son and hence, Y-chromosome analysis can help in identification of father of this young boy.
Answer:
Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth ...
Explanation:
Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.
London dispersion force:
- The weakest intermolecular force is called the London dispersion force.
- When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
- There are instances when this force is referred to as an induced dipole-induced dipole attraction.
Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.
<u><em>Butane:</em></u>
- It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.
