The answer is C & E

Answer:
The transfer of energy through empty space is called convection.
Explanation:
One of the fundamental laws of the universe is the conservation of energy. Energy can't be created and it can't be destroyed. Convection can be the process by which heat is transferred . Temperature is known as the basic principle of heat transfer. The amount that how much of thermal energy can be available is determined by the temperature, and the heat flow represents movement of thermal energy.
Answer:
The options
a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Explanation:
Answer:
An "Asterism" is best defined as: <u>A, A popular group of stars or pattern in the night sky</u>
Explanation:
Essentially, an asterism (a recognizable pattern of stars) is part of a constellation, a larger group of stars that cover a region/area of the sky. For example, the Big Dipper is an asterism that is part of the constellation Ursa Major (aka Great Bear).
