The smallest unit of matter that has the characteristic properties of it’s element is called an “atom”.
Individual atoms are called “elements” for that reason.
There are smaller divisions of matter, however those no longer have the characteristics of the element that they may be a part of. A hydrogen electron is indistinguishable from an argon electron, or any other.
A fossil will most likely be found in a sedimentary rock.
Ecosystems can be large and are made of biomes. Some examples of ecosystems are deserts and forests.
Mitochondria and chloroplasts likely evolved from engulfed bacteria that once lived as independent organisms. ... Eukaryotic cells containing mitochondria then engulfed photosynthetic bacteria, which evolved to become specialized chloroplast organelles.
The answer is prokaryotes
There are choices for this question namely:
<span>1 Lifelong passive immunity
2 Long lasting active protection
3 Immediate passive short term immunity
4 Stimulation for the production of antibodies
</span>
The correct answer is "immediate passive short term immunity". The administration of tetanus immunoglobulin will directly attack toxins associated with tetanus for a short time, providing short term immunity and this effect is immediate.The passive immunity from tetanus immunoglobulin is not lifelong. Choices 2 and 4 talks about active immunity which is not characteristic of tetanus immunoglobulin injection.
