Answer:
2.84*10^-3 years = 0.00284*10^-3 years
Explanation:
To find the orbital period you use the following formula:
r: 2.0A = 2.0(1.5*10^11m)=3*10^11 m
G: Cavendish constant = 6.67*10^-11 Nm^2/kg^2
M: mass of the sun = 1.98*10^30 kg
Next, you calculate the time in seconds of one Earth's year:
thus, you use this value to find the orbital period of the asteroid in Earth's year:
Answer:
The answer is - To serve as an outgroup
Explanation:
The options are;
a) to see if the lily and the orchids show all the same shared derived characters (synapomorphies)
b) to demonstrate likely homoplasies
c) to see if the lily is a cryptic orchid species
d) to serve as an outgroup
The answer is D- To serve as an Outgroup
A phylogenetic tree is also called an evolutionary tree and it shows the evolutionary relationships that exists among organisms called taxa based on their physical or genetic similarities and differences. The Phylogenetic tree consists of ingroup and outgroup. The ingroup consists of a group of closely related organisms or taxon while the outgroup represents a more distantly related group of organisms or taxon but as close as possible to the ingroup.
The Lily represents the outgroup in the phylogenetic tree while the Orchid are the ingroup. This is because the Lily is distantly related to the orchid.
