1
A nucleotide derived from adenosine that occurs in muscle tissue; the major source of energy for cellular reactions.
2
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.
3
A type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
4
Endangered Species: Threatened by factors such as habitat loss, hunting, disease and climate change, and usually have declining populations or a very limited range.
5
An enzyme that catalyzes the formation of cyclic AMP from ATP.
6
The energy that an atomic system must acquire before a process (such as an emission or reaction) can occur.
7
Any of various molecules that are capable of accepting one or two electrons from one molecule and donating them to another in the process of electron transport.
8
Transport of a substance (as a protein or drug) across a cell membrane against the concentration gradient; requires an expenditure of energy
9
The local voltage change across the cell wall as a nerve impulse is transmitted.
10
The study of organic particles, such as bacteria, fungal spores, very small insects, pollen grains and viruses, which are passively transported by the air.
11
The branch of biology that studies the development of gametes (sex cells), fertilization, and development of embryos and fetuses.
12
The part of an enzyme or antibody where the chemical reaction occurs
13
Animals, like flatworms and jellyfish, that have no body cavity (coelom). Semi-solid mesodermal tissues between the gut and body wall hold their organs in place.
14
The female gametophyte of a seed plant, within which the embryo develops. ... (in flowering plants) a large cell of the rudimentary seed, within which the embryo develops.
15
Depending on free oxygen or air.
New game
