Honors Biology EOC Practice Questions with Verified Solutions How do transport proteins assist in moving molecules across the cell membrane? Transport proteins facilitate the movement of molecules across the cell membrane by providing specific pathways for substances to enter or exit the cell. What is the role of the Golgi apparatus in a cell? The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. How do the two stag...

Aristotle, a philosopher - Answer-Pre-300 BCE -described species as fixed -Scale of nature: arranges species in order of lowest to highest complexity -linear hierarchy Hutton, a geologist - Answer-1795 -proposed gradualism -change is a slow but continuous process Thomas Robert Malthus, an economist - Answer-1798 -published "Essay on the Principle of Population'" -Human population growth is limited by resources; At some point we will reach carrying capacity, -can't grow exponentiall...

HSC Biology Module 5 Reproduction Reproductive success The ability to produce fertile offspring that survive to reproductive maturity and produce offspring of their own. Biological fitness the measure of an individual's reproductive success. It is calculated as the average contribution to the gene pool made by a certain genotype within a population and the relative likelihood that these alleles will be represented in future generation. Sexual reproduction It involves the meet...
