Answer:
It is used to identify the most recent common ancestors and to recognize how closely related species are. To relate the milestones of the evolution of major life forms to the tree of life. To represent evolutionary relationships between organisms that are believed to have some common ancestry.

Photosynthetic organisms use the process of photosynthesis to produce their energy. During this process they also take in carbon dioxide and release oxygen. If there were less of such organisms, there would be more carbon dioxide and less oxygen in the atmosphere.

Answer:
Burning coal
Explanation:
The emissions of carbon dioxide would reduce because then they will consume less gasoline. Instead of coal burning, this would reduce the overall concentrations of greenhouse gas emissions and generate energy from wind.
The answer is A. 0.54.
In a population p+q=1 (we have 2 alleles only).
The question states that 0.21 of the population(21%) have short legs meaning they are q^2.
So q=rad0.21=0.4582.
And p=1-q=0.5417.
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
