20 is the Number of Neutrons of potassium.
Answer:
The environment usually refers to all the biotic and the abiotic components that are surrounding us. This environment undergoes changes depending upon various factors which can be natural and/or due to the anthropogenic activities.
When there occur rapid environmental changes, then it directly affects the lives of species, in different ways, such as-
- Those species that are comparatively weaker in adapting according to the environmental changes that occur, will not be able to cope up with the new environment. They may become extinct.
- Some variety of species will be able to adapt to the new environment because of their easily adapting capabilities.
- The traits that will be developed within the species in the new environment will be more successful in terms of reproduction.
- The previously existed traits may have a harmful impact in the newly formed environment.
I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
<h2>The answer is:</h2>
B) All organisms that cannot synthesize their food by means of photosynthesis or chemo synthesis are heterotrophic.
<h2>Explanation:</h2>
All those organisms that cannot manufacture their own food and instead obtains its food and energy by taking in organic substances in the process of photosynthesis usually in the animals and plants. All animals, protozoans, fungi, and most bacteria are heterotrophs.
Answer:
The correct answer is - Archaea or archaebacteria.
Explanation:
Archaea is the domain and the kingdom of the single-cell prokaryotic organisms as they lack a nucleus. These organisms are present in extreme habitats such as hot springs, high saline water. These organisms can live in extremely aggressive environments which makes it a uniqe characteristic of this organism.
In the given condition the organism that lives in hypersaline water is most likely a member of the Archaea domain or Archaebacteria kingdom as it is found in the hypersaline waters of Southeastern Australia and unicellular organisms.
