Answer:

The correct answer is - The axis must be tilted at a certain angle that."  remains unchanged.

Explanation:

On the earth there ae many seasons but there are four major season, winter, summer, spring and autumn. The main reason that leads to all four season is the tilt of the sun at a specific angle that remain unchanged  which leads to change in the distance to the sun at specific time of the year which result in different rays of sun the part. So, whatever hemisphere or part tilted towards the sun leads to different season for instance:

North pole tilted towards the sun - summer in northern hemisphere

south pole tilted towards the sun -  winter in northern hemisphere

If the extracellular fluid has an excess of sodium ions, a. sodium ions move into cells b. intracellular fluid moves to the outs
Mandarinka [93]

Answer:

b. intracellular fluid moves to the outside of cells

Explanation:

The presence of an excess of sodium ions in the extracellular fluid would make it hypertonic with respect to the intracellular fluid. The concentration gradient would drive the intracellular fluid towards the outside of the cell to balance the concentration of the fluids on either side. The passive movement of fluids occurs across the cells and is driven by the concentration gradient only. The biological membranes are permeable for fluid movement such as the movement of water across it.

If the force exerted on a sled is 100 N and the mass of the sled is 50 kg, what is the acceleration of the sled?
Anna35 [415]
<h3><u>Answer;</u></h3>

acceleration= 2 m/s²

<h3><u>Explanation;</u></h3>

From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.

That is;

F = ma

Thus; F = 100 N, m = 50 kg

a = F/m

  = 100/50

  = 2 m/s²

A generalist predator does which of the following
Degger [83]

Answer:

Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.
