Dive Biology Terms Lesson 22

Mitochondria – an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
Pancreas – secrete insuline & glucagon to regulate blood sugar levels
Promoter – region of DNA that indicates to an enzyme where to bind to make RNA
metaphase – stage of mitosis when the spindle is complete and the chromosomes, attached to microtubules at their kinetochores, are all aligned at the metaphase plate
chromosomes – Threadlike structures made of DNA molecules that contain the genes.
deductive reasoning. – reasoning that begins with premises assumed to be true and develops specific conclusions.
capture and transfer energy – function of the light dependent reaction
commensalism – one organism benefits and the other is neither hurt nor helped
organ – anatomical unit made of tissues that serve a common function
Phase of Mitosis do the spindle fibers disappear and new nuclear membranes and two new nuclei from around the chromosomes – Telophase
The watery liquid located in the anterior cavity of the eye is the
chemotherapy – Treatment of cancer by a chemical that kills rapidly dividing cells, specifically cancerous cells.
B2:Systems in Homeostasis – 1.RECEPTORS- Detect change in environment
2.PROCESSING CENTRES-receive info and determine body response
3.EFFECTORS-Produce response
Homeostasis – the steady-state physiological condition of the body
phloem – in the root of a dicot, the _________ fit between the "arms of the x"
The wаtery liquid lоcаted in the аnteriоr cavity оf the eye is the
A concentration gradient exists when one area has a higher concentration of a substance than another area does – true
metabolism – Chemical reactions in living organisms that are necessary to maintain life
Photosynthesis – 6CO2 + 6H2O –> C6H12O6 + 6O2 , A process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates, such as sugars and starches.
autosomes – Chromosomes that are not directly involved in determining the sex of an individual.
polymer – a large molecule made from smaller units(monomer)
