:the act or action of propagating: such as. a : increase (as of a kind of organism) in numbers. b : the spreading of something (such as a belief) abroad or into new regions. c : enlargement or extension (as of a crack) in a solid body. What does propagation mean in plants? Pl...
The mean density of large prey species differed significantly among habitats for decapods and echinoids (nested ANOVA,F2,14.4= 5.225,P= 0.020 andF2,21.8= 4.322,P= 0.026, respectively). Decapods and echinoids were significantly more abundant on coral reefs than in mangroves and seagrass beds (Figu...
Spermatazoa are the male gamete,meaning they are the cells that fuse with the egg in fertilization giving rise to the embrion and future baby.
It recognizes the reproductive intent of those who, say, do not contribute a gamete to the process, or of a female who does not gestate the child she intends to rear. It also recognizes instances where an individual or couple intend to rear a child whom they neither beget nor bear, in...
Saying `I was not a little upset' when you mean `I was very upset' is an example of litotes Common Curiosities What is the purpose of mitosis in multicellular organisms? Mitosis is essential for growth, cellular repair, and asexual reproduction in multicellular organisms. 14 How does meiosis ...
You’re searching the database and land on a donor you really like – she played your favorite sport as a child and her eyes remind you of your mother’s. Then you notice she is listed as an “open release donor” and your mind races – What does this mean? What am I signing up...
Nondisjunction may occur whenever a cell divides its chromosomes. This happens during normal cell division (mitosis) and gamete production (meiosis). Mitosis DNA replicates prior to cell division. The chromosomes line up in the middle plane of the cell during metaphase and the kinetochores of sister...
In order to make that argument, we first need to establish what it would mean for aging to exist as a single, objective phenomenon, what we refer to as a “unitary phenomenon.” Some 20–30 years ago, many researchers in the biology of aging believed aging was due to a single ...
