Staar Biology

Asexual reproduction – Reproduction accomplished by a single organism
Light dependent – Reaction of photosynthesis that requires light; light energy is absorbed converted to chemical energy in the form of ATP and NADPH
Biodiversity – The variation in life forms that exist in a particular location. We can look at this variation on many different levels but the term is mostly used to refer to the number of varieties of living things at the ecosystem and biosphere levels.
Finite resources – Natural materials that exist in limited quantities and will be gone forever once they are used, unless they can be recycled. See "renew."
a) the beetles would become spotted –
gemmule – A means of asexual reproduction found in sponges, they are made up of a group of cells covered by a tough protective coat. When harsh conditions kill the parent, they remain dormant. When conditions improve, the gemmule opens and a new sponge begins to grow.
The cell membrane – is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.
activation energy – kinetic energy required to initiate a chemical reaction
Phase of Mitosis where the chromosomes condense and spindle fibers attach to the centromeres of the sister chromatids. – Prophase
Abnormal condition of death (cells and tissue die because of disease)
Passive immunity – An individual does not produce his or her own antibodies, but rather receives them directly from another source, such as mother to infant through breast milk
Autotroph – Organism that makes its own food; producer
Unicellular organism – an organism made of a single cell
interphase – Cell grows, copies its DNA, and prepares for division; consists of G1, S, and G2 phases
Abnоrmаl cоnditiоn of deаth (cells аnd tissue die because of disease)
Autotroph – An organism that obtains organic food molecules without eating other organisms or substanes derived from other organisms. These use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.
Experimental, Panspermia, Cosmozoic – This theory of origin of live believes that live started from a spore
Who was Charles Darwin and what did he contributed to the understanding of science? – Englishman who was first to describe the theory of evolution, traveled the world on the USS Beagle.
anabolic pathways – Metabolic pathways that consume energy to build complicated molecules from simpler ones.
Pneumonia – Inflamation of the lungs, caused by: bacteria(streptococcus pheumoniae) , viruses, or fungy.
