The correct answer is D. More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory.

Explanation:

In biology, selection occurs as certain organisms with adaptative characteristics prevail over time as they are more likely to reproduce and survive, while organisms with other characteristics disappear. This process can occur by artificial means as human beings intervene in selection.

According to this, the one that is an example of artificial selection is "More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory", because in this case, elephants without tusks are more likely to survive and reproduce and due to this, they are more common today which explains selection. However, this process occurred mainly because of poachers which means there is intervention from human beings and therefore the selection is artificial.

Eva8 [605]
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>

Answer:

Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.

Explanation:

  • As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth.  Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
  • Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
  • On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.

Please see attached image for better understanding.

Hope it helps!
