Cell, tissue, organ, organism, population, community, ecosystem, biosphere

A population and ecosystem both include organisms, however a population is one type of species while an ecosystem is both biotic and abiotic things.

DNA, cytoplasm, ribosome, and plasma membranes

Any organism capable of self nourishment to get energy

To protect the nucleus and filter particles

Proteins, nucleic acids, carbohydrates, and lipids

an organism that consists only of 1 cell eg. bacteria/microorganisms

Constructive metabolism that synthesizes more complex substances from simple substances

A large naturally occurring community of fauna and flora occupying that habitat

Made up of 2 hydrophobic tails for each hydrophilic head. Structure is flexible and changes shape easily due to fluidity. Structure is strong due to attraction between hydrophobic tails

the feature that can't be directlytaken from the features of its simpler parts eg. the taste of salt w/ the combination of Na+Cl

Used to build and maintain the membrane, and modulates membrane fluidity

acrosomal contents to the outside of the sperm and exposes the inner acrosomal membrane proteins on the sperm's outer plasma membrane

water is attracted to other substances

Watson and Crick

Each cell in a multicellular organism contains all of the genes of that organism. The genes that are activated are different for each cell in our body to have its own function. Cells will develop in their own ways by differentiation which depends on the gene expression

Smallpox vaccine

Store extra bile from the liver

tracheids, vessels, parenchyma, and fibers

Singer and Nicolson

Scientists had experimented and found the cell was the smallest piece of living matter that could live on its own, and because of these units were so small, they were named cells. Cells could only reproduce from living matter, because cells cannot reproduce unless the cells can perform cell reproduction, which is impossible with a dead cell

those it spreads across, maximizing contact — are known as hydrophilic. Those that naturally repel water, causing droplets to form, are known as hydrophobic

A red blood cell;
with hemoglobin, carries oxygen in the blood.

the resting potential, threshold, the rising phase, the falling phase, and the recovery phase

short sections of DNA formed at the time of discontinuous synthesis of the lagging strand during replication of DNA.
