Currently, two of the living elephant species (X and Y) are placed in the genus Loxodonta, and a third surviving species (Z) is

placed in the genus Elephas. Assuming this classification reflects evolutionary relatedness. Draw the most accurate evolutionary tree.

Answer:

Explanation:

The evolutionary tree is composed of,

  • Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches ⇒ Elephant species X, Y, Z
  • Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor ⇒ The red spot in the graph shows the location o the most recent ancestor between species X and Y
  • Root → This is the older common ancestor that all lineages share. The first one in the tree ⇒ The blue spot in the graph show the oldest common ancestor shared by the three species

Two or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.

Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.

Myofibrils are made primarily of
Nadusha1986 [10]

Answer:

A) actin and myosin  is a correct answer.

Explanation:

  • Myofibrils are the contractile fiber and they are made of actin and myosin.
  • Myofibrils are made of thick myofilaments and thin myofilaments.
  • Thick myofilaments are made up of myosin whereas thin     myofilaments are composed of actin.
  • The functional unit of muscle is Myofibrils and contraction of muscle occurs due to myofibril, when the filaments actin and myosin interact with each other.

Thus Myofibrils are made primarily of (A) actin and myosin.
