<em>Homo neanderthelensis</em> or Neanderthals are the close relatives of the <em>Homo sapiens</em> or modern humans which became extinct around 10,000 years ago.
The Neanderthals and sapiens are the two related species of the same genus Homo but they showed distinct features like Neanderthals were muscular and shorter in height compared to the <em>Homo sapiens</em>. Recent fossils indicated that Neanderthals and<em> Homo sapiens</em> interbreed in some parts of the world as they were closely related to each other.
Thus, Option-B is the correct answer.
Answer:
<u>Option-(A,D):</u> Consistent fitness benefits of high allocations to defense and differing strategies for overcoming plant defenses among herbivores.
Explanation:
The plants or primary producers are there in order to provide the optimum amount of energy for the different beings to survive, but there are some limitations for each living being itself and for that reason the plant life have also evolved it self not be over consumed by the herbivores or the primary consumers. As the herbivore are also evolving through time as they assembled there system and chemical balances that corresponds to any of the harmful material present inside the plants body and during the ingestion of such body parts the herbivores may be effected. So,they have evolved there body system in order to make some arrangements for confronting any complication faced by them.
Correct answer: A) A small structure within the cell that serves specialized functions
Organelles are small,specialized structures found inside the cell which perform a specific task and help in the functioning of the cell.
Organelles are known to be found in all the eukaryotic cells. There they serve a essential and specialized functions such as making proteins, getting rid of waste, harvesting energy etc.
Example: Mitochondria, endoplasmic reticulum, nucleus etc.
Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?
B phenotype (think pheno= physical)
