Why is fossil record hard to interpret?
Ever since and before Darwin's time, evolutionists have repeatedly insisted that all species of life have descended from a common ancestor as a result of a purely natural process of adaption to changing circumstances. So in lieu of the existence of any present proof for evolution, Darwin said that the only evidence of it would come from examining the fossil record. Thus if evolution did occur, one would expect to find a gradual series of fossils embedded in the rocks, from simple "almost life" chemicals, to one-celled creatures, then two-celled creatures, on and on with greater complexity until you have the sponges and algae, the chordates and the trilobites and all of the invertebrates, then the vertebrates appearing animals with backbones, these last including fish, amphibians, reptiles, and man. That is only the Animal Kingdom; there is still the Plant Kingdom to be considered, with grapes and giant sequoia trees, carrots and flowers, potatoes and lawn grass, all of which supposedly evolved from the same common ancestor, according to evolutionists. Darwin stated that many of the great scientists of his time held the fossil record up as evidence against evolution, not for it.

Why evolution is a theory?
The theory of evolution was developed by Charles Darwin, an amateur English naturalist, in the 19th century. He proposed that all of the millions of species of organisms present today, including humans, evolved slowly over billions of years, from a common ancestor by way of natural selection. This idea said that the individuals best adapted to their habitat passed on their traits to their offspring. Over time these advantageous qualities accumulated and transformed the individual into a species entirely different from its ancestors. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival - a process known as "natural selection." These beneficial mutations are passed on to the next generation.

Last Blog Of Semester
My favorite activity was aerobics because im going to lose weight. My least favorite was Math because that class is so borning and the teacher doesn't teach that good. One thing I would change is for me to do all of my work.

Explain how contamination of one animal in a food web can affect other animals
Food contamination can be microbial or environmental, with the formerbeing more common. Environmental contaminants that can enter the food supply chain include pesticides, heavy metals, and other chemical agents.Many opportunities exist for food to become contaminated as it is produced and distributed. Toi start with, bacteria are present in the animals raised for food. Meat and poultry can become contaminated during slaughter through cross-contamination from intestinal fecal matter. Similarly, fresh fruits and vegetables can be contaminated if they are washed using water contaminated with animal manure or human sewage. During food processing, contamination is also possible from infected food handlers. Lastly, poor hygiene in the home is also a factor.
Should we be able to choose the traits of our babies?
In the movie Gattaca the parents are able to choose there traits of there babies. I think that parents shouldn't choose there kids traits. One reason is because kids wouldnt be kids they would be different cause of the traits the parents pick for them. If parents never picked traits for there kids they would come out normal and unique. So I think we shouldn't be able to pick traits for our babies.

STD'S
Jenny: OMG Laliii i want pizzaa and tatertots. !
Lali: Ahhh Youuu Fattieeee. Ahahaa.
Jenny: Dudee im in 4th period and theres this major cutie in my class. !

Jenny: Hit It Quit Say i Never Did It.? (; Ahahaa. <3
Lali: Thatss Wasssuupppp (; But Ayee i Would Check If His Clean First Cause Today In My Bio Class We Were Talking About STD'S. ! Other than HIV, the most common STDS in the United States are chlamydia,gonorrhea, syphilis, genital herpes, human papillomavirus, hepatitis B, trichomoniasis, andbacterial vaginosis.
Jenny: Omg. ! For reals.?! Ahh Thatt Neverr Crossed My Minddd. ! Soo i Should See If His Clean Or Not.?
Lali: YESSSS !!!!!!!!!!!!

Helpful Bacteria/Harmful Bacteria
We actually have helpful bacteria that exist on this earth and you may be shocked at how helpful they are both to the environment and to human beings as well. The Rhizobia bacteria, is a group of helpful bacteria that converts nitrogen gas into other useful substances that help plants to grow well. The E. coli bacteria, are also helpful bacteria that live in the intestines of living people and animals such as cows, giraffes and goats. These bacteria help a lot in food digestion for both people and animals. The E. coli bacteria in an organism's body to be very important due to the fact that, without them, proper food digestion may fail to take place hence complicating things for the organism. Azotobacters are other types of helpful bacteria found on earth.These bacteria stay in the soil and are able to convert gaseous nitrogen to ammonium compounds.
Disease causing bacteria gain entry to your insides through inhalation, ingestion or a break in the skin. Some familiar sounding diseases, or life inconveniences, caused by bacteria include:
