Scientists break down evolution into which two categories?

microevolution and macroevolution

macroevolution and genetic drift

microevolution and mass extinction

natural selection and macroevolution

Option A, microevolution and macroevolution

Explanation:

Scientist have categorized evolution base on the time scale  into following two categories

a)Macroevolution – These are the processes which take a long time to occur such as formation of a new species, extinction of any rare species etc, Also it affects a large mass of population or the entire population

b)Microevolution – In this,  the processes of change take a short time and usually they impact only a certain set of species for a shorter time period.  

Thus, option A is correct.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
