AP Biology UNIT 8 Ecology 8.4 Effect of Density on Populations Video
Ever wondered how population density affects survival in ecosystems? In this video, we break down the effect of population density and how limited food, water, and living space can impact organisms. You'll learn how dense populations increase competition, spread disease faster, and change how species interact with their environment. We also explore how ecosystems like rainforests, savannas, deserts, and wetlands support different population sizes based on available resources and carrying capacit

AP Biology UNIT 6 Gene Expression 6.3 Transcription & RNA Processing Video
In AP Biology Unit 6.3, transcription is the process where RNA polymerase reads a DNA template strand to synthesize a complementary RNA molecule. In prokaryotes, transcription occurs directly in the cytoplasm and the mRNA can be translated immediately with little or no modification. In eukaryotes, transcription happens inside the nucleus and the initial RNA transcript must undergo RNA processing, including the addition of a 5′ cap, a poly-A tail, and splicing to remove introns. These modificatio
