storchak [24]

Answer:

Multiaxial joint

Explanation:

Joint is understood as the set of structures that allow the union of two or more bones and / or cartilage with each other. The synovial joint is a union that is established between bones that have different articular surfaces. There are factors that determine the axes of space in which a joint can be mobilized, in such a way that uniaxial, biaxial or multiaxial joints are identified. The multiaxial joint is movements in around three axes or three degrees of freedom. These joints can perform any movement. This movement that is carried out in the three axes is called circumduction movement (in a circle). The movements that a synovial joint can carry out are sliding, extension, flexion, abduction, adduction, medial rotation, lateral rotation, circumduction, protrusion, retrusion, diduction, pronation, supination, inversion, eversion, among others.

Diastole is the ________ phase of the cardiac cycle.
STatiana [176]
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.

Help!! I'm doing a lab report and am unsure which variables are independent, dependent, and controlled. My lab is due tomorrow
victus00 [196]

Im not sure but if you think of it, the one that you didn't put any salt is a independent  variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !
