Parasites can have large effects on their host populations and communities; can determine the competitive balance between two species, whether one species can invade or coexist with another; change the flow of energy through and relative balance of different trophic levels; act as “ecosystem engineers” to change the environment in which other organisms live; have cascading effects on entire ecosystems, determining their biomass or diversity. Indirect interactions Direct interactions a...

A biology exam covers a wide range of topics, incorporating detailed aspects of cellular biology, genetics, and biochemistry. Students may encounter questions related to cellular respiration (C6H12O6 + 6O2 → 6CO2 + 6H2O) and photosynthesis (6CO2 + 6H2O + light energy → C6H12O6 + 6O2), exploring the intricacies of metabolic pathways. Genetic concepts like DNA replication, transcription, and translation are integral, involving molecular processes and chemical structures such as nucleotides (A,...

ecology “the study of the processes determining the distribution and abundance of organisms” (Krebs) or of “the interaction among organisms and between organisms and their environment” (Poulin) In infectious disease (ID) context: incidence (number of new infections per unit time) and prevalence (number of infected individuals in the population). We may also be interested in the parasite burden or intensity of infection: how many bugs/host on average? How do we get this information?...

simple easy notes

Extensive effort put into condensing long lecture notes into these that were used to study for the exam

AS and A level Biology

Corresponding to IGCSE Edexcel Pearson Biology specification (information likely to apply to/cover other exam boards). Highly detailed notes, includes step-by-step methods and examples (where helpful to topic) and annotated diagrams. FREE!

Embryo development is a topic related to plant development biology in the Botany. It gives information on the endosperm development during seed formation. Thenceforth it a good class note to be referred.
