Answer:
Erosion
Explanation:
Weathering is the travel from wind that leads to things being in new places like seeds.
Infiltration is adding things in to something, such as adding salt to water.
Answer:
I think it is A
Explanation:
The other ones appear to be all true. And they would not be able to know if Raptors had feathers if fossils only formed from the hard part of the animal.
Answer:
Study of comparative anatomy emerged in the 18th century and led to establishment of relationship between species based on the common traits
Explanation:
The three major events that occurred after this discovery are –
a) Discovery of the fact that the age of earth is much higher than the age of earth as found in previous theories of continental drift theory
b) The age of the oldest fossils was determined and based on that relative age of all species (as found in fossils) was determined.
c) The determination of age of fossil helped to find the gaps in the evolutionary tree and hence provoked search of these missing species.
The study of comparative anatomy started somewhere around 1800 when George Cuvier emerged as father of comparative anatomy
Based on comparative anatomy study, scientists such as Buffon and Lamarck worked on establishing relationship between species based on the common traits shared between them
Explanation:
Isotopes:
₁₅³¹P and ₁₅³²P
Given parameters:
₁₅³¹P ₁₅³²P
Mass number = 31 32
Atomic number = 15 15
The two atoms are isotopes. Now let us derive numbers of their subatomic particles
₁₅³¹P ₁₅³²P
Protons 15 15
Electrons 15 15
Neutrons (31-15) = 16 (32-15) = 17
Because they are isotopes, they differ in the number of neutrons alone.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of their neutrons.
We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.
