Answer:
No, there are some organisms that only have one cell, although there are organ systems that are made up of many cells. Not all organisms have organ systems.
Explanation:
For example, the Trichoplax. It is an animal with no organs that is tiny and multicellular, and only feeds on microalgae. A Trichoplax are flat organisms about a millimetre in diameter with no internal structures and typically have two cellular layers. These organisms live in the oceans and seas all around the world but are not necessarily found in their natural habitat, more so in captivity such as a marine aquarium. Trichoplax are found to live in symbiosis with such things as bacteria and others in the oceans and seas.
Precipitate is silver sulfate and the net ionic equation is
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
<u>Explanation:</u>
The given reaction is the reaction of sodium sulfate with silver nitrate and as the reaction goes we will get the precipitate of Silver sulfate and the balanced reaction is given as,
Na₂SO₄ + 2 AgNO₃→ Ag₂SO₄↓ + 2 NaNO₃
Here silver sulfate is obtained as a precipitate.
Net ionic equation is the equation in which the ions involved in the reaction only taken into account that is ions forming precipitate, whereas the other ions are considered as spectator ions, ions do not involved in the reaction.
Here the net ionic equation is:
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
Answer:
Wavelength of this beam of light: .
Explanation:
The speed of light in vacuum is approximately .
Light behaves like a wave. The wavelength of a wave is equal to the distance that it travels (in the given medium) in each period of oscillation.
On the other hand, the frequency of a wave is the number of periods in unit time. means one oscillation per second. The frequency of this particular wave is . In other words, there are oscillations in each second.
The period of oscillation will be equal to
.
In that period of time, a beam of light in vacuum would have traveled
.
In other words, if this beam of light of frequency is in vacuum, its wavelength will be equal to .
A proton is a positively charged particle found within the nucleus of an atom, a neutron carries no charge and is also found in the nucleus. An electron is a very small negatively charged particle found in the outer "shells" or orbitals of the atom.
