1 answer:

3 0

Nitrogen is essential to life. It is a component of all proteins and can be found in all living organisms. Nitrogen in the atmosphere. The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with bean plants.

Answer:

1-As winds rise up the windward side of a mountain range, the air cools and precipitation falls.

2-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls.

3-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks.

4-Rain shadow deserts are formed because tall mountain ranges prevent moisture-rich clouds from reaching areas on the lee, or protected side, of the range.

5-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks. So there is very little precipitation on the leeward side of a mountain range.

6-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks. So there is very little precipitation on the leeward side of a mountain range.

8. A 60 kg runner has 1500 J of kinetic energy. How fast is he moving?

tresset_1 [31]

Answer: 7.07 m/s

Explanation:

Mass of runner = 60 kg runner

Kinetic energy = 1500J

Speed of runner = ?

Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass and speed by which it moves.

Hence, K.E = 1/2 x mass x (speed)^2

1500J = 1/2 x 60kg x (speed)^2

1500J = 30kg x (speed)^2

(speed)^2 = 1500J/30kg

(speed)^2 = 50

To get the value of speed, find the square root of 50

speed = √50

speed = 7.07 m/s

Thus, the runner moves as fast as 7.07 m/s

1.) What things signal the coming of spring?

olasank [31]

Answer:

In Explanation

Explanation:

The signs of the coming of spring include firstly the sight of Robins. It is believed that the sight and singing of the Robins is considered arrival of spring by many in the US. Secondly, the winter is not yet over but the blooming of Daffodils first of all flowers is indication of the spring. As the air gets warmer the flowers bud and new leaves start growing on trees since the days also begin to get longer providing much warmth which also an indicator of the spring.
Without the axial tilt of our Earth, firstly, the Sun would have remained above the equator (Equinox) forever but fortunately due to the tilt we get equinoxes twice a year and not forever. Moreover, the temperature and precipitation levels would not vary much and the equator would remain always warm and the poles always cold. Secondly, due to the tilt as the Earth orbits around the Sun and with changes in solstices we get variety of the seasons which would have been impossible otherwise.

Ions are unequally distributed across the plasma membrane of all cells. This ion distribution creates an electrical potential di

nekit [7.7K]

Answer: Resting Membrane Potential

Explanation:

The resting membrane potential refers to the difference in voltage between the inside and outside of the cell membrane when the cell is at physiological rest. It should be noted that the cell membrane is a selective semipermeable barrier, which only allows the transit through it of certain molecules and prevents the transit of others.

This selectivity causes an uneven distribution of charged particles (ions), as the membrane only accepts some types of ions.

Now, in the case of neurons, which are electrically excitable nerve cells; the transport of electrical signals is due to these changes in the permeability and asymmetric distribution of ions (mainly sodium and potassium) when the neuron is not excited (at rest).
