In a cladogram, a group of organisms branch off when a new trait evolves. Cladograms are braching diagrams where each branch represents an evolutionary lineage. A cladogram uses lines that branch off in different directions ending at groups of organisms.

The following options are attached to the question above:

A. When a new trait evolves

B. When an ancestor becomes extinct

C. When it is discovered

D. When it becomes large enough

ANSWER

The correct option is A.

A cladiogram refers to diagram that is used to show the relationships among organisms. The diagram make use of lines, which branch off in different directions and which end up at a clade. A clade refers to a group of living organisms that share a last common ancestor. The diagram is used by biologists to visualize group of organisms that are been compared in order to determine their relatedness and their most common ancestors. In cladiogram, a group of organism branch off when a new trait emerge.

Describe the role of smooth muscle in two human body systems other than the cardiovascular system.

Ahat [919]

<h2>Human Body Systems</h2>

Explanation:

Cardiac and skeletal muscle and cardiac(heart) are both striated in appearance, while smooth muscle isn't.
Both Cardiac and smooth muscle are automatic while skeletal muscle is deliberate.
Cardiovascular muscle is likewise an automatic muscle yet is progressively associated in structure to skeletal muscle, and is discovered uniquely in the heart.
Smooth muscles move nourishment through the stomach related tract.
In one's eye the pupillary sphincter muscles is answerable for contracting the size of the student.
Smooth muscle developments keep up the supply routes' breadth. Smooth muscle controls wind stream in lungs.
Heart muscles are striated not normal for smooth muscles.
Cardiovascular muscles are found in the heart dividers and aorta while smooth muscles are found in most of blood vessels and internal organs.
