Chordae tendineae are found in the A. auricles. B. ventricles. C. atria. D. aorta.
creativ13 [48]
B. ventricles

The chordae tendinae, also referred to as heart strings, are tendons that connect the atrioventricular (tricuspid) valves to the muscular wall of the heart. These chords are made predominantly of collagen, while the remaining part is elastin. They play the vital role of maintaining the structure of the valves they connect to. Due to the high pressure generated within the heart, it is entirely possible for the atrioventricular valves to turn inside out. The chordae tendinae prevent this from happening and keep the valves functioning properly.

frozen [14]

Answer:

population density

population distribution

age structure

Explanation:

if we look at this question; it looks glaring that it correlates with a fill in the blank type of question.

So, from the question:

Frank counts 56 maple trees living on a 20-acre tract of land, and the data allows him to calculate the <u>population density</u> of the maple trees on the land.

In an ecological succession, population  density refer to species of  a common genera in specific geographical setting. It helps to measure the exact number of organism inhabitant a unit area of a place.

He observes that most of the maple trees grow closely together in groups of 6 to 8 trees, which describes the <u>population distribution. </u>

Population distribution is the spread of organism over a region in a geographic ecological setting. The pattern of distribution of organism may be uniform , in some  organism they are largely dispersed and in some they are clumped together.

The<u> age structure </u>of the maple trees shows the percentages of trees of different ages.

The age structure is also a term used in ecology which is normally use to predict the proportion of growth of organisms. Age structure  of  species in the environment speaks volume about their  distribution of age.

Predict which mechanism of reproductive isolation played a role in trumpeter speciation in the Amazon basin. Note: Trumpeters ca
Alexandra [31]

Habitat isolation is likely to be most relevant in the case of trumpeters in the Amazon basin.

If trumpeters can not cross rivers, then they would be able to mate with trumpeters on the same side of the river but not on the other side- a form of prezygotic isolation.

what are trumpeters?

The term "trumpeter" comes from the deep, booming territorial call of these chicken-sized, long-necked, hunch-backed, small-headed, short-tailed, dark-plumed, long-legged birds that wander the jungle floors of South America.The land of South America that now the Amazon River and its tributaries drain is recognized as the Amazon basin.

What does mutation mean?
Alecsey [184]
A mutation is a genetic error in the creation of DNA. My science teacher compared it to a copier that made a mistake; the DNA is copied from others, but the "copier" messed up, making part of a helix different. Mutations can be genotypes or phenotypes.
