STatiana [176]3 years ago

Diastole is the relaxation phase of the cardiac cycle. It is the normal rhythmic dilation of the heart's valves. During this time, the valves start to gather blood inside of their chambers. There are two types of diastole that occur in the heart, and they are:

1. Ventricular diastole - this is the period where the ventricles are filling and relaxing. 
2. Atrial diastole - the period in which the atria are relaxing. 

This is a continuous cycle that occurs in the heart the moment a person is conceived until the person meets his/her death.

Travka [436]

The correct answer is co-adaptation.  

Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.

loris [4]

The lack of adaptations to the habitat most likely caused the walleye to move to a different river.

Adaptation

It is a biological mechanism that increases the chance of its survival in a new environment or the changes in the existing environment. Adaptation occurs as a result of evolution and allows the organism to survive and reproduce efficiently in its environment.

Physical adaptations include accumulating changes in the physical characteristics of an organism that help them to survive and reproduce better. Example: evolution of long necks in giraffes.

Behavioral adaptations are changes in the behavior or habits of organisms that help them to sustain in a changing or new environment. Example: Hibernation.

Due to some reason, the walleye were not able to adapt to the environment of the east river which is why they must have moved to a new river despite the presence of a lot of prey.
