Ok where did the very first living organism ever come from? Do you believe in evolution which states that the first living organism ever. The first simple single-cell organism that appeared billions of years ago...where did the very first living thing ever come from? Did it literally "evolve" from nothing? To me that is one of the biggest downfalls of evolution. How can you say that something "evolved from nothing? The very first living thing ever in the history of time had to come from somewhere. And I don't buy that it came from nothing.

Also if possible how would i get them or make them?

As a teacher of AP biology, I know that biological evolution happens. I know that many biologists call the terms "microevolution" and "macroevolution" an artificial distinction. I agree. However, the terms are used in both the textbook I issued to my students (Solomon, Berg, and Martin's "Biology" 7th ed) and in the CliffsAP Biology study book that I have.

Solomon, Berg, and Martin describe microevolution as a shift in allele frequencies within a population (not within a species, although that would be a natural consequence, wouldn't it?) They define macroevolution as large-scale changes that result in the formation of new species, genera, families, etc.

The CliffsAP book says that microevolution includes speciation, and that macroevolution describes patterns of change in groups of related species over broad periods of geologic time.

The CliffsAP book is geared toward AP students, but most other sources have speciation as part of macroevolution. How do I approach this?

The same "scientist" who hoaxed human cloning, now says that he has genetically engineered cats that glow in the dark when exposed to ultraviolet light.

Render unto me a friggin break!

I've got psychedelic posters at home that do the same thing!

What do you think?

In an experiment we did in a lab class, we put the enzyme Beta Galactosidase (b-gal) in a test tube with ONPG, a lactose-mimicking chemical. We put the tube in a Spec 20 to measure the absorbance. As the ONPG was broken down by b-gal, the solution in the tube turned yellow.
We tested this at several different temperatures and measured the absorbance at 15 seconds. At low temperatures, the absorbance was very low. Warmer temperatures showed a higher absorbance. However, temperatures that were "too high" showed a lower absorbance.
My question is, what does absorbance even mean? Why do we see this trend in the enzyme data?

i believe there must be a self-evident, all inclusive, and more humanstic understanding of existence. one that accounts for time and space, history, and everything contained therein.
example: Life is a birth. The universe is a living entity and stars and planets are cells and cell structures. The galaxies are organs, the milky way is a uterus, the earth is our fertilized egg. The sun is the endometrium, the soil is the placenta, the grasses are microvilla, the foodchain is an umbilical cord. Water is the universe's maternal blood, streams and rivers are veins and arteries, animals and organisms are roving cells, the air is an amionotic fluid mixture, the ozon layer is the aminion sac, forests and wetlands are filterization & other systems, & humans are the individualized cells and cell structures of the human spirit. Life is a birth process, a beginning, and God is our father waiting outside our humble womb... sounds strange, but compare you sciences w/the act of birth.

Food contains both purine and pyramidine bases. But, from the books and teachers, we learned that the cell adops the denovo synthesis or salvage pathway.
But my question is:
Why are exogenous purines and pyramidines not incorporated into the cell's DNA/ RNA?

My postgraduate student posed this question. I went through couple of biochemistry and molecular biology books. And I also googled. I need an answer to satisfy student.

As the title says. I thought the greater the p your experiment is more correct. For my experiment I used three classes of beans and got about 80-70% p in my results. I thought this was good because my expected was kinda close to my observed result, (about 6 away from expected). I read online though that its the opposite or something like that and that the farther away from .05, the less reliable it is. The closer it is to .05 then that means the more likely it occurred by chance and the farther from .05 the more likely it was biased and something affected the results??? Can someone please explain to me what exactly p stands for??? I am very confused...

Suppose you are looking at a sample of pond water, and your see a single celled organism swimming in the water. It's green, and moves quickly.
Hey! I have an answer to this, but I'm not sure if it's right! :)


There's a clear picture of a nucleus, but you can't see any other organelles with your compound light microscope.

In what kingdom does this organism belong? What other characteristics do you expect this organism to have?
