A hypothesis is a ___.
Aloiza [94]

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. <u>It is a specific, testable prediction about what you expect to happen in a study.</u>

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that <em>The hypothesis</em><u> is a simple statement that defines what you think the outcome of your experiment will be.</u>

21. The Function and Organization of the Motor System Controlling Flight Maneuvers in Flies (Drosophilla (fruit fly))
viva [34]

The effects of Function and Organization of the Motor System Controlling Flight that flies possess a strong equilibrium reflex wherein angular rotations of the body elicit compensatory modifications in each the amplitude and stroke frequency of the wings of Drosophilla.

The daunting challenge of controlling their limbs the usage of a small set of rather restricted actuators. This problem is specifically demanding for insects along with Drosophila, which need to alter wing motion for both quick voluntary maneuvers and sluggish compensatory reflexes the use of only a dozen pairs of muscles.

Techniques through which animals execute particular movements using sparse motor networks, the hobby of a entire ensemble of wing manage muscles in intact, flying flies. Our experiments uncovered a remarkably efficient good judgment in which each of the skeletal factors at the base of the wing are ready with each large active muscle mass able to executing big adjustments and smaller tonically energetic muscular tissues specialized for non-stop quality-scaled modifications.

Can someone help me understand interphase, prophase, metaphase, anaphase, and telophase
Tcecarenko [31]

Answer:

They are all stages of mitosis, which is cell division (for new cells for repair and growth)

interphase- the longest stage of the process. The DNA in the chromosomes copies itself, ready to split for mitosis. ALL 23 pairs copies itself so now there is 46 pairs of chromosomes (23 for each new cell).

prophase- The DNA in the chromosomes are more visible now, and the membrane around the nucleus disappears ready for the next stage

metaphase- Chromosomes and their copies line up in the middle of the cell, so that they could be pulled apart in the next stage

anaphase- Spindle fibres attach themselves to either end of the chromosome. They are then pulled apart to either ends of the cell. 23 on one side, 23 on another.

telophase- membranes form around the 23 pairs of chromosomes at their end of the cell. Two new daughter cells are produced. The cell membrane pinches in and divides the cells in two.
