Get a picture of alternation of generations put it in your blog and explain how it relates to plants

Alternation of generations (also known as alternation of phases or metagenesis) is a term primarily used in describing the life cycle of plants (taken here to mean the Archaeplastida). A multicellular diploid sporophyte, with N paired chromosomes (i.e. 2N in total), alternates with a multicellular haploid gametophyte, with N unpaired chromosomes. A mature sporophyte produces spores by meiosis, a process which results in a reduction of the number of chromosomes by a half. Spores germinate and grow into a gametophyte. At maturity, the gametophyte produces gametes by mitosis. 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. This cycle, from sporophyte to sporophyte (or equally from gametophyte to gametophyte), is the way in which all land plants and many algae undergo sexual reproduction.

Why is dissection an important part of a biology curriculum? Which animals and/or plants should be included in biological studies?

Dissection is important because it is usually the process of disassembling and observing something to determine its internal structure and as an aid to discerning the functions and relationships of its components.lt is necessary to use it in order to do much deeper research.Without to cut it out,we can only see the organism's cover,and it's not enough.However,l think the animals or the plants which is in danger should be included in biogical studies because after we keep on studying,it may have some breakthrough which can help them.

Blog 9 Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each

competition occurs when organisms of the same or different species attempt to use an ecological resource in the same place at the same time.for example,tiger and lion may compete each other by fighting for their prey.
predation is an interaction in which one organism captures and feeds on another organism.such as panther is depend on sheep or other animal to be its food.it needs to eat them in order to survive.

in mutualism,both species benefit from the relationship.many flowers depend on certain species of insects to pollinate them.they both get good advantage from each other.

in commensalism,one member of the association benefits and the other is neither helped nor harmed.for example,small marine animals called barnacles,often attach themselves to a whale's skin.yet,the barnacles benfit from the constant movement of water past the swimming whale,because the water carries food particles to them.however,whales do not have any disatvantage.

in parasitism,one organism lives on or inside another organism and harms it.as a parasite obtains all or part of its nutrientional needs from the other organism.
