What is the difference between unicellular and multicellular organisms?

1 answer:

8 0

Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.

A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.

Maslowich

The production of an electric current by a changing magnetic field is known as electromagnetic induction.

The phenomenon when the current is produced due to changing magnetic field is given by Faraday.

And this phenomenon is called the electro-magnetic induction or magnetic induction since the electricity is generated due to the fluctuations or variance in the magnetic field.

The human eye is most sensitive to green light of wavelength 505 nm . Experiments have found that when people are kept in a dark

liq [111]

1. $5.94\cdot 10^{14} Hz$

The frequency of a photon is given by:

$f=\frac{c}{\lambda}$

where

c is the speed of light

$\lambda$ is the wavelength

The wavelength of the photon in this problem is

$\lambda=505 nm=5.05\cdot 10^{-7}m$

So, the frequency of the photon is

$f=\frac{3\cdot 10^8 m/s}{5.05\cdot 10^{-7} m}=5.94\cdot 10^{14} Hz$

2. $3.94\cdot 10^{-19}J, 2.46 eV$

The energy of a photon is given by

$E=hf$

where

h is the Planck constant

f is the frequency of the photon

The frequency of the photon in this problem is

$f=5.94\cdot 10^{14} Hz$

so its energy in Joules is

$E=(6.63\cdot 10^{-34}Js)(5.94\cdot 10^{14}Hz)=3.94\cdot 10^{-19}J$

And since

$1 eV = 1.6\cdot 10^{-19}J$

The energy in eV is

$E=\frac{3.94\cdot 10^{-19} J}{1.6\cdot 10^{-19}J/eV}=2.46 eV$

Any example of acceleration related to human body??? answer quickly plz :)

Hitman42 [59]

Answer:

Acceleration stress, physiological changes that occur in the human body in motion as a result of rapid increase of speed. ... A force of 3 g, for example, is equivalent to an acceleration three times that of a body falling near Earth.

When can we be certain that the average velocity of an object is always equal to its instantaneous velocity?

balandron [24]

Answer:

Average velocity is said to be equal to the instantaneous velocity when acceleration is zero. When acceleration of an object is equal to zero, there can be no change in speed or direction.
