Answer:

Work

Explanation:

Work can be referred to as the application of a force (F) over a distance (d). In other words, WORK is done when an applied force causes a body to move. Hence, work is a product of the force and the displacement in the direction of the force i.e. W = F × d

In this case, a desk is PULLED along the floor in your classroom, this best indicates WORK because a force (pull) is applied on the desk causing it to move over a distance in the direction of the pull.

On topographic maps, how does the spacing of contour lines relate to continental and ocean-floor topography? A. For both contine
Trava [24]

For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.

Explanation:

The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.

The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.

Some elements of the contour lines or that go with them to give better representation are:

  • black dots (representing a top)
  • thicker lines (every fifth, so that the counting is faster and easier)
  • small lines with given direction (representing cliffs or highly steep slopes)
  • numbers (providing information about elevation)

Which of the following statements about aldosterone is NOT correct?- Aldosterone is stimulated by decreased plasma sodium levels
lisov135 [29]

Answer:

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation;

  • Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney.Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium.
  • When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the .body to maintain the high water levels in the body.

people once believed organisms could grow from food or dirt.How might the scientific study of cells have affected this view?
almond37 [142]
It proves that living organisms MUST come from other living organisms, an egg couldn't magically appear in a pile of chicken seed, a hen would have had to lay the egg first, just as a nucleoulus makes ribosomes so the cell can have proteins, the proteins don't just materialize within the organism.
