Answer: Independent variable

 

An independent variable is a condition in a scientific study that is changed or manipulated to test the effects on the dependent variable. The experimenter controls the value of independent variable and its value represent inputs or causes like potential reason for variation.

Additionally, there are tendencies that independent variables are included in a scientific study especially if the experimenter has no intention to test their effect directly.

Muscles that move the eyeball have ________ fibers.
ozzi

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.

<h3>What are fast muscle fibers?</h3>

Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.

Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.

Therefore, the correct option is A.

Contribution of prophase stage of mitosis cell division to growth of plant
seraphim [82]

Answer: Spindle Formation

Explanation:Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved. Cohesin is retained, however, at the most constricted part of the chromosome, the centromere (Figure 9). During prophase, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
