2. What is the difference between an organ and an organ system

2 answers:

The difference between an organ and a tissue is that basically tissues are a group of similar cells that works together. Then a group of tissue that works together would make up an organ. Groups of organ working together later makes up an organ system. This is the main difference between an organ and a tissue.

The difference is an organ system is made of a GROUP of ORGANS that are working to do a specific job while a organ is made up of a group of TISSUES, not group of organs, but tissues, to work in harmony to do a specific job. So basically the organ system is in its name, system of organs, so that helps u see that its a group of organs running together.

Naoki's bicycle has a mass of 10 kg. If Naoki sits on her bicycle and starts pedaling with a force of 168 N, causing an accelera

White raven [17]

Answer:

50 kg

Explanation:

Data:

Mass of bicycle = 10 kg

F = 168 N

a = 2.8 m/s²

Calculation:

F = ma Divide each side by m, Then

m = F/a

= 168/2.8

= 60 kg

m = mass of bicycle + Naoki's mass. Then

60 = 10 + Naoki's mass Subtract 10 from each side

Naoki's mass = 50 kg

A 0.45-g sample of aspirin is decomposed into its constituent elements and found to contain 0.27 g C, 0.020 g H, and 0.16 g O. C

slamgirl [31]

Answer:

Explanation:

mass % of C = 0.27/0.45*100 = 60%

mass % of H = 0.02/0.45*100 = 4.4%

mass % of O = 0.16/0.45*100 = 35.6%

Total = 60%+4.4%+ 35.6% = 100%

In a hypothetical atom, electron N transitions between energy levels, giving off orange light in the transition. In the same ato

Zielflug [23.3K]

Answer : Electron P has greater energy difference than the Electron N.

Explanation :

Wavelength range of violet light = 400 - 500 nm

Wavelength range of orange light = 600 - 700 nm

The Planck's equation is,

$E=\frac{h\times c}{\lambda}$

where,

E = energy of light

c = speed of light

$\lambda$ = wavelength of light

According to the Planck's equation, wavelength and energy follow inverse relation. As the wavelength increases, energy decreases.

From the given spectrum, the wavelength of violet light is less. We conclude that When electron P gives violet light on transition it means that energy difference between the energy level was high.

From the given spectrum, the wavelength of orange light is more. We conclude that When electron N gives orange light on transition it means that energy difference between the energy level was low.

So, Electron P which gives violet light on transition has greater energy difference than the Electron N.

What is a chemical formula, and what does it tell you?

katrin2010 [14]

Explanation:

chemical formula tells you the specific elements included in the compound and the number of atoms of each. The letters in a chemical formula are the symbols for the specific elements. So for example, H means hydrogen.
