Translation – the process in which cellular ribosomes create proteins. In translation, messenger RNA (mRNA)—produced by transcription from DNA—is decoded by a ribosome to produce a specific amino acid chain, or polypeptide.
Prokaryote – Cells with NO nucleus
Punnett square – model for predicting all possible genotypes resulting from a cross, or mating.
Plasmodesmata – channels between cells for transport
pellicle – a firm, flexible coating outside the plasma membrane
Nucleus – the central membrane-bound organelle that manages or controls cellular functions.
nucleus – contains the cell's genetic material (DNA) and controls the cell's activities
WHY IS YEAT USED TO MAKE BREAD RISE? 2 – Yeast carries out fermentation, producing ethanol and carbon dioxide
Aldosterone – A hormone released by the
adrenal glands that increases
sodium reabsorption to
maintain the water-salt
balance
The fibrous joint in which a cone-shaped peg fits into a socket. The example is the root of a tooth:
animal kingdom traits.. – multi-cellular heterotrophs and no cell wall
density – the ratio of mass to volume of an object
BMI – (Body Mass Index) = body mass (kg) / height^2 (m)
Cell walls – provide rigidity to plant cells (and some bacteria) and are not found within animal cells.
pH – Acidity or Alkalinity; measured by a scale of 0 (most acidic) to 14 (most alkaline) One unit of a pH scale means a ten-fold difference in acidity or alkalinity.
The fibrоus jоint in which а cоne-shаped peg fits into а socket. The example is the root of a tooth:
Why was Darwin's theory controversial when he first came up with it? – – Because of strong religious beliefs of the time (God created everything etc.)
– He didn't have much evidence to back it up
Builder for RNA – RNA Polymerase
500. Parts of Blastocyst: – Thicker mass of cells becomes embryo.
Rest of blastocyst develops into membranes that surround, nourish and protect the embryo
