Plz mark as brainleast plzzz :)
The correct option is B.
A multi cellular organisms has many cells which carry out various function and which are organised into tissues, organs and organ system. A unicellular organism on the other hand has only one cell with different cell organelles. Thus, in unicellular organisms, it is the cell organelles that carry out different functions. <span />
Answer:
B
Explanation:
The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.
In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.
If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)
However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.
<span>Answer: Biodiversity</span>
The suppression of forest fires causes a decrease in biodiversity because
some habitats require exposure to fire. Most ecosystems of savanna, chaparral
and coniferous forests have developed with fire as an essential contributor to habitat’s vigor
and regeneration.
Additionally, wildfire suppression eliminates plant species
in fire-affected environments that require fire to germinate, established, or to
reproduce. Also, animals that depend on these plants will be affected too.
