Answer:

D- Indicates common ancestors

Explanation:

A phylogenetic tree shows evolutionary relationships among organisms.  This tree establishes the common ancestry and divergence points of each species from the common ancestor. These relationships are not definite facts and do not show the exact time of divergence among species of common ancestry.

The pattern of branching in a phylogenetic tree shows how species or other groups evolved from a series of common ancestors.  Two species are more closely related, if their ancestral link is more recent and less closely related if their ancestral link is less recent.

A phylogenic tree, uses branches to establish the relationships between common ancestors and species, each branch point, indicating common ancestry among offspring.  The farther the branch points from the common ancestor and other members of the species, the farther the relationship among them.

Answer: Option D.

Explanation:

A phylogenetic tree is a brach diagram that shows the relationship among species of organisms in a taxa base on their differences and similarities of physical characteristics and genetic characters indicating common ancestors.

The tips of the tree represent descendents of the taxa and the node represent the common ancestors of the descendants. It uses branches to represent relationships among species, common ancestors and also descendants of the ancestors.

A client with a history of seizures is admitted with a partial occlusion of the left common carotid artery. the client has been
lord [1]
The correct answer is to obtain a thorough history of the seizure type and incidence. The patient is already taking phenytoin for 10 years so there must be an underlying seizure disorder. The type of the seizure (absence, tonic-clonic, etc.) should be characterized as this will affect the management of the patient. Placing an airway in a patient without respiratory distress is unnecessary and may even produce traumatic injury to the patient. Asking to remove dentures and eyeglasses is also unnecessary.

Sauron [17]

Answer:

The correct answer is (a). The brown beetle migrated to island #1 and gave rise to the colored species on island #2 through adaptive radiation.

Explanation:

As there are no brown beetles on the island 1, and island 2 has less biodiversity of plants, it's possible to think that the brown beetle migrated to island 1 where there are many kinds of different plants, which would lead to the adaptation of these organisms resulting in many different species.
