Answer:
A) The male stamens hold the pollen, the female pistil holds the ovule, and the petals attract pollinators.
Stamens (male reproductive parts of a flower) collectively forms the male reproductive organ (androecium) in a flower whereas pistil (the female reproductive part of a flower) forms the female reproductive organ called gynoecium.
Stamen consists two parts that are anther (that produces pollens, male reproductive cells) and a stalk like structure called filament, which supports/ holds pollen producing anther.
The female pistil holds the ovule that is enclosed by ovary in flowering plants (angiosperms) and the petals in a flower attract pollinators.
Thus, option A) is the right answer.
Explanation:
Surprisingly, until recently, not much was known about the genes that control melanin production. 6 were known (MC1R, TYR, OCA2, SLC24A5, MATP and ASIP) and 17 more have been recently identified (DTNBP1, GPR143, HPS3, KITGL, MLPH, MYO5A, MYO7A, SLC45A2, TYRP1, ERCC6, GNAS, HERC2, IRF4, OBSCN, SKC24A5, TPNC2 and MITF), all of them directly or indirectly related to the process of melanin formation and distribution. Since there are so many different genes, if we count all the possible alterations, many different color variants can be produced.
Answer:
The correct option is D. (Hippocampus)
Explanation:
Hippocampus is known as the part of the brain and situated in the bottom middle section inner folds which are called the temporal lobe. The main function of the hippocampus is memory and learning. It plays an important role in retrieve two types of memory which are known as declarative memories and spatial relationship memories.
1) Declarative memories: It is related to events and facts such as learning how to memorize lines.
2) Spatial relationship memories: It is related to routes and pathways such as when a driver learns pathways through the city.
Dissolved gasses under lots of pressure are being trapped in the magma, these expanding gases and steam are what causes it. Also, because of this heat getting more and more hotter, and the volume being lost due to the gasses over time the lava bursts out.
