Answer:
gene flow is the transfer of genetic variation from one population to another.
option D
Answer: the graph supports: background extinctions, mass extinctions affected the evolution of mammals and dinosaurs
The graph does not support:both mammas and dinosaur revolved in the pattern of gradualism, dinosaurs evolved by adaptive radiation, and convolution affected the evolution of mammals and dinosaurs
Explanation:The graph only shows mass extinctions and background extinctions
Answer:
D: All of these options
Explanation:
The p-values for the coefficients indicate whether these relationships are statistically significant.
A low t value shows that your hypothesis is true
Multicollinearity means when independent variables in a regression model are correlated.
Answer: The answer is B
Explanation:
Cellular respiration harvest most chemical energy from converting oxygen to ATP. During cellular respiration, most ATP produced are generated by oxidative phosphorylation , which uses the energy released by redox reactions in the electron transport chain to male ATP. The electrons are finally passed to oxygen which is reduced to water.
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
