Blog #10 Dissection

Why is dissection an important part of a biology curriculum?  

         The reason why dissection is important for biology is because it keeps the classroom more interested. Not only that but instead of seeing a  picture of it and trying to figure out how parts work and where they are, you can have a student be up close and personal with the dissection. For me when i dissected a cow eye and a squid, i actually remembered more clearly where everything was and how to dissect. Usually when you're confronted with something, you tend to remember exactly where everything is. It just becomes sort of part of a memory. So dissecting can be part of a good studying technique.

Which animals and/or plants should be included in biological studies?

         I think we should dissect a cow eye, just because in past experiences its been really interesting. Also maybe dissecting a frog, squid, baby pig. Also dissect a fish, just to see how difficult it is since they are so tiny. I can't think of anything else. But anything really interesting and out of the ordinary would be great to dissect.

Blog #9 Community Interaction

Competition: Is a contest between species and other organisms that compete to live.

Commensalism:two different kinds of organisms that benefit from another without hurting it.

Mutualism:When two organisms interact but also get benefits from each other.

Predation:  Where a predator feeds off of its prey.

Parasitism:When one organism benefits from the other organism by damaging it.

Blog #8 What I Learned / Questions

Well after doing some of these recent blogs I've been learning about how this world we live in has so many biomes. You look at how much space a certain biome takes up, and what kind of characteristics it has, like what type of animals live in those areas. Also how certain plants live in specific biomes, and cant be found anywhere else. Also how the biomes were formed so many yeas ago. It just really makes you think about nature, and what it has to brign to the future. But our human race tends to be blind to the beauty of these biomes, and we decide that we need it for more useless space.

Blog #7 Two Biomes

Forest Biome:

1/3 of Earths land area

2/3 of leaf area of land plants

70% carbon in living things

worshipped in ancient religions

dominated by trees and other woody vegetation

there are different classifications of forests such as :

-tropical forest

-temperate forest

-boreal forest

Grassland Biome

dominated by grass

to types of grasslands:

-savannas

-temperate grasslands

hills of grasses and wildflowers

grasses and small plants

has some rain during the year

Blog #6 Which level of a food pyramid is the most important?

Well i believe that every single level of the food pyramid is very important, but at the same time i think that fruit is a little more important than the rest. It reduces the risk for having strokes and other cardiovascular diseases, and it reduces the risk of type two diabetes. Also give have nutrients such as potassium, dietary fiber, vitamin C, and folate. Fruits basically give you a lot of health benefits and nutrients.

Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?

 Well it is said that 3 species are getting extinct every hour. Which is a lot.... they say that humans could be tha cause for he 6th extinction but not completely our fault. It could also be caused by natural causes such as .....transformation of the landscape ...over exploitation of species....pollution.... the introduction of alien species. But i guess you can say that humans are part of the reason why.

Blog # 4 Describe the three types of selection

Directional: process when a trait becomes more common within a population
Stabilizing:  process where heterozygotes arew used instead of homozygotes,to maintain a genetic           stabilty
Disruptive: a change in the populations genetics, caused by extreme phenotypes
