Answer:
Diffusion
Explanation:
The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.
For example:
Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.
While,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
If you mean organelles then chloroplast
No,not all organs are weighed on a triple beam balance.
<u>Explanation:</u>
- Usually smaller sized organs like adrenals, thyroid are commonly used to be weighed on triple beam balance, whereas larger organs like lungs, liver and heart can only be weighed on grocer's scale.
- Only weight of the smaller body organs can be measured very precisely with the help of triple beam balance, where as if we measure the weight of the larger organs using the same triple beam balance,then the resultant value thus obtained will not be accurate enough.
- Hence organs are weighed on a triple beam balance.
Cells have unique characteristics wherein each develop a specific function determined by the activation of certain DNA sequences to generate this specific cell into its supposed design, this is why cell specialization exists.
Hence, these cells can be directly identified with their morphological structures and the DNA sequences they posses.
