Answer:
i really really need the brainly points
Explanation:s
sry for the answer
If he studied a small sample it wouldn't be a representative sample. since he got such a large sample there is a chance most likely all organisms follow the rules of evolution.
Answer:
Conditioned stimulus
Explanation:
The conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
Populations tend to grow because of repopulation.
-carbohydrates contain carbon , hydrogen and oxygen
-also known as saccharides
-glucose is a hexose monosaccharide (composed of 6 carbons )
-two structural variations: alpha α and beta β glucose ,in which the OH group on carbon 1 is in opposite positions
- glucose : polar and soluble in water due to the bonds that form between the hydroxyl groups and water molecules
-glycosidic bond : bond formed between two glucose molecules by a condensation reaction forming a disaccharide
-fructose +galactose =sucrose
-galactose +glucose = lactose
- starch :many alpha glucose molecules can be joined by glycosidic bonds to form two slightly different polysaccharides
- one of the polysaccharides of starch is called amylose
- amylose : formed by alpha glucose molecules joined together only by 1-4 glycosidic bonds
-amylopectin: both 1-4 and 1-6 (every 25 glucose subunits )glycosidic bonds between alpha glucose molecules. 1-6 glycosidic bonds cause branching
-glycogen : more branches than amylopectin . Compact so ideal for storage . Speeds up the process of storing and releasing glucose molecules required in the cell.Insoluble
-hydrolysis reactions opposite of condensation reaction
-cellulose:beta glucose molecules. Join together by alternate beta glucose molecules turn upside down
- straight chain molecule: cellulose
-cellulose molecules make H bonds with each-other forming microfibrils. Microfibrils join together to form macrofibrils which combine to produce fibres
