Quotes About Biology

I learn something I didn't know about the human body : if your mom cries, you cry.

time, cost, or safety concerns. • MasteringBiology: Virtual Biology Labs offer unique learning experiences in microscopy, molecular biology, genetics, ecology, and systematics. • Choose from 20–30 automatically graded, "pre-set" lab activities that are ready to assign to students, or create your own from scratch. • Each "pre-set" lab provides an assignable

Down there between our legs, it's like an entertainment complex in the middle of a sewage system. Who designed that?

The four most common chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth. We are not simply in the universe. The universe is in us.

If a huge genetic gap separated us from our closest relative in the animal kingdom, we could justifiably celebrate our brilliance. We might be entitled to walk around thinking we're distant and distinct from our fellow creatures. But no such gap exists. Instead, we are one with the rest of nature, fitting neither above nor below, but within.

If you removed all the arteries, veins, & capillaries from a person's body, and tied them end-to-end…the person will die.

Collectively, these findings tell us it's conceivable that life began on Mars and later seeded life on Earth, a process known as panspermia.

I learned in biology class that more bacteria live and work in one centimeter of my colon, than the number of people who have ever existed in the world. That kind of information makes you think twice about who–or what–is actually in charge.

If all the molecules on Earth were stacked on each other end-to-end, everything on Earth would die.

From that day on, I began to think of people not as the masters of space and time but as participants in a great cosmic chain of being, with a direct genetic link across species both living and extinct, extending back nearly four billion years to the earliest single-celled organisms on Earth.

Within the chemically rich liquid oceans, by a mechanism yet to be discovered, organic molecules transitioned to self-replicating life.

One could make a compelling argument that we know more about the universe than the marine biologist knows about the bottom of the ocean or the geologist knows about the center of Earth. Far from an existence as powerless stargazers, modern astrophysicists are armed to the teeth with the tools and techniques of spectroscopy, enabling us all to stay firmly planted on Earth, yet finally touch the stars (without burning our fingers) and claim to know them as never before.

Three quarks for Muster Mark!" One thing quarks do have going for them: all their names are simple—something chemists, biologists, and especially geologists seem incapable of achieving when naming their own stuff.

life began on Mars and later seeded life on Earth, a process known as panspermia.

Your body has to come up with about 100 watts of energy to keep yourself warm

Between 1 and 10 quadrillion ants live on (and in) Earth

The four most common, chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth, with carbon serving as the foundation of biochemistry. We do not simply live in this universe. The universe lives within us.

A fontos, ám ellentmondásos felvetés azt állítja, hogy a Földön található fajok egy kollektív organizmust alkotnak, ami folyamatosan (ám akaratlanul) úgy szabályozza a bolygó atmoszférájának összetételét és klímáját, hogy az biztosítsa az élet feltételeit – és ezzel a folyékony víz jelenlétét.

Which came first, the chicken or the egg? The egg, laid by a bird that was not a chicken.

If it weren't for Jupiter, you can justifiably question whether Earth could have ever made it from simple life to complex life." ?

My first ideas of human in vitro fertilization (IVF) arose with my Ph.D. in Edinburgh University in the early 1950s. Supervised by Alan Beatty, my research was based on his work on altering chromosomal complements in mouse embryos.

I'm interested in using evolution to move forward into the future, to get biology to do a lot of new chemistry for us.
