On a branching chart showing the evolution of species over time what does each branch represent
2 answers:
Answer:
The correct answer would be species.
Phylogenetic tree refers to the diagrammatic representation of evolutionary relationships among different organisms.
The branching pattern indicates how species evolved from a sequence of common ancestors.
The tip of each line or branch indicates a separate species.
Each internode or branching point represents a divergent event in which a single group splits into two descendant groups.

1. Answer: components
A two dimensional vector can be divided into two parts called horizontal component and vertical component.
A three dimensional vector can be divided into three components: one along x-axis, one along y-axis and one along z-axis.
Hence, the vector parts that add up to the resultant are called components.
2. Answer: 5 miles.
The resultant distance along the straight line from the starting point to the end point would be the displacement.
The displacement would be equal to the magnitude of the hypotenuse formed in the right triangle.
Displacement,
3. Answer: Scalar
A scalar quantity has only magnitude. For example, speed and distance are scalar quantities and can be normally added to find the total.
A vector quantity has both magnitude as well as direction. The components are summed according to vector addition rules. For example, velocity, acceleration, force etc.
