Answer;

-Atrial contraction;

Explanation:

-The cardiac cycle comprises all of the physiological events associated with a single heartbeat, including electrical events, mechanical events (pressures and volumes), and heart sounds.The atria and ventricles alternately contract in each cardiac cycle.  The pressures in the chambers change greatly over the course of the cardiac cycle.

-During atrial contraction, blood flows from atria (high pressure) to ventricles (low pressure). Similarly, this same pressure gradient exists during ventricular filling.

To be able to grasp the concept of the answer, let us discuss a bit on what commensalism; herbivore is.

Commensalism as a word is basically biological phrase in which during the relationship between  creatures of different species or the same specie( for instance, lets say we have Specie A and Specie B).

Which one of the following accurately describes the Lac operon?
Zepler [3.9K]
D. The repressor is freed from the operator when lactose is present.
Think of a bacteria that comes into contact with some lactose sugar in milk. Normally it's not in milk, so the gene is repressed (prevented) from making the lac enzyme (which digests lactose). Now when it comes across some milk, it wants to make as much lac as possible to eat up all the lactose.
FYI: trp for tryptophan works the exact opposite with repressor blocking when trp IS PRESENT.
