a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
Answer:
an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Explanation:
The number of times per week that exercise is performed is known as frequency.
Exercise frequency answers the question how many times you workout per week total. This includes weight training workouts, cardio workouts.This is value that can vary depends on many factors specific to individual (age, weight, condition). Because of this, it’s impossible to say exactly how often(how many times) everyone should be working out per week total.
In fetal circulation, the ductus venosus bypasses the liver and the ductus arteriousus bypasses the lungs. Ductus arteriosus also called ductus botalli is a blood vessel connecting the main pulmonary artery to the proximal ascending aorta. It does allow most of the blood from right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Ductus venosus on the hand allows oxygenated blood from the placenta to bypass the liver.
Answer:
The circulatory system consists of the heart, the arteries, veins, and capillaries.
