Answer:

osmosis

Explanation:

another kind of diffusion. - diffusion of water through a differentially permeable membrane from a region of high concentration to a region where the concentration is lower. osmotic pressure. of a solution is a measure of its tendency to draw water molecules into it by osmosis.

Answer:

Osmosis. The direction of water movement across the cell membrane depends on the concentration of free water.

A molecule of roughly spherical shape has a mass of 6.10 × 10-25 kg and a diameter of 0.70 nm. The uncertainty in the measured p

Ilia_Sergeevich [38]

Answer:

$\Delta v = 0.123 m/s$

Explanation:

As per the law of uncertainty we know that

$\Delta p \times \Delta x = \frac{h}{4\pi}$

now we know that

$\Delta x = 0.70 nm$

$m = 6.10 \times 10^{-25}$

also we have

$h = 6.626 \times 10^{-34} J.s$

now we will have

$m\Delta v \times \Delta x = \frac{h}{4\pi}$

$(6.10 \times 10^{-25})\Delta v \times (0.70 \times 10^{-9}) = \frac{6.626 \times 10^{-34}}{4\pi}$

$\Delta v= 0.123 m/s$

Estefan has determined his BMI at 31. Explain how he can apply the FITT training principles to improve his body composition.

-BARSIC- [3]

Frequency:

Cardio : Five or more
HIIT: 5 or 4

Strength: 2-3 days on non-consecutive days a week

Intensity:
How hard you work during the session

For cardio : workout at your target heart rate.
For HIIT: varying intensity from high to low or rest ( no slow pace)
For strength: you should lift enough weight to complete the needed number of reps and sets.

Time:

For cardio 30- 60 min
For HIIT 45 min (short periods of bursts followed by rest)

For strength depends on the amount of weight.

Type:

Either cardio, HIIT or strength training (resistance training)

How does the matter and (solar) energy move through the sphere?

Tema [17]

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

Describe the valence electrons in nitrogen and how it could bond to other atoms?

Gekata [30.6K]

Answer:

Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond. This is because each nitrogen atom has 5 valence electrons. Each atom can complete its octet by sharing three electrons.

I hope this helps!
