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

The alternation of generations relates to plants because it is a term that is used in describing the life cycle of plants. This treats the alternation of multicellular diploid forms of plants with a multicellular haploid form as the defining characteristic.

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 lets the people who want to learn about what the animal has in the inside of it or something they can't see and really want an answer about it.  I don't know if these animals/ plants are already being studied as we speak but, the animals that I think are interesting and that should be studied should be wild animals that nobody ever sees.  They should be studied since no one really knows what they inside their bodies and would be really interesting to see what they have inside their bodies. Some plants as the ones in the forest.  Their are beautiful flowers and plants in the Forest that no one has ever seen before and no one might not even know their characteristics.  They should really studied to see what they have or even if they can cure an illness.

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

Competition:
In ecology, the interaction between two or more organisms, or groups of organisms, that use a common resource in short supply. 







Sea Anenomes compete for the territory in tide pools


CommensalismIn ecology, commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit).




Barnacles attaching to scallops, not harming them. 


Mutualism- Mutualism is the way two organisms biologically interact where each individual derives a fitness benefit




A hummingbird benefitting from a flower, however the flower also benefits from it by getting pollinated.


MutualismIn ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked).







Praying mantis eating a bee. 


Parasitism- A type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host.
