Answer:
The subject definition has always been listed in the overview section elsewhere here.
Explanation:
Something you are attempting to calculate is a variable. It can be something, such as things, quantities of time, emotions, actions, or thoughts. If you're researching how people here feel regarding specific tv programs, television shows as well as emotions are the factors throughout the analysis. If you are learning how various forms of fertilizer influence how tall plants develop, fertilizer form and plant height seem to be the variables.
<u>Independent Variable</u>
- The independent variable seems to be the variable whom the adjustment is not influenced throughout the analysis by every other variable. Usually, the researcher herself needs to modify the independent variable or it adjusts by itself because nothing influences or adjusts this one in the project.
<u>Dependent Variable</u>
- Throughout the analysis, the dependent variable that's what's being examined but instead evaluated. As something of a consequence of the modifications to something like the independent variable, that's what modifications.
Answer:
1. Sympathetic input increases ventricular contractility, thereby increasing stroke volume.
2. Sympathetic input decreases conduction time within the heart, decreasing the delay between atrial and ventricular contractions.
3. Sympathetic input increases the speed of ventricular contraction.
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force<span> (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. </span><span>If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant. the source i found this answer is, https://www.mansfieldct.org/Schools/MMS/staff/hand/lawsunbalancedforce.htm

Answer:
Flatworms and cnidarians
Explanation:
In simple organisms, such as cnidarians and flatworms, every cell in the body is close to the external environment. Their cells are kept moist so that gases diffuse quickly via direct diffusion. Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane
