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.
Chemical reaction hope this helped :)))
Answer:
Both are type of natural selection and ultimately lead to selection of a set of phenotype over the entire available genotype spectrum.
Explanation:
Both the stabilizing selection and directional selection are two forms of natural selection
Also in both the selection process, a new population with a better fitment to the prevailing environmental and physical conditions evolves.
In stabilizing selection, an average phenotype is selected over extreme variation. However, by this process of selection the genetic variance of the population will decrease.
However in directional selection, phenotypes at one end of the existing variation are selected over the entire spectrum
Answer:
Explanation:
To reduce the incidents of destruction of field by this animals the Spanish could have helped adapt by taming the animals, the animals can be kept in a ranch where they would be controlled to prevent them from entering fields.
The American India could be enlighten through orientation about how to keep their farms save from invasion by this pest animals.
The India should be enlighten about the animal and its mode of operation and how to prevent the entry of this animal pest into their field. This will help them adapt to animal.
With this the India would be able to feel loved and start adapting to the new changes.
More widely available food chain for other predators, an increase in population of the prey.
