the appearance of nodules or bumps on the root of the plant. It helps the plant by giving it usable nitrogen and in return the bacteria gets energy from the plant itself. This relationship of two organisms benefiting from each other is called mutualism. Then heterotrophs‚ organisms that consume other organisms for energy‚ eat the plants and take in their nitrogen. When animals urinate they also pass nitrogen back into the soil or water to be re -used. Which substance‚ rhizobium‚ nitrogen (in the

Ecosystem Components and Interactions I. Introduction An ecosystem is a complex relationship between a community of organisms and the environment that they dwell in where energy is exchanged and transformed. Ecosystem includes the biotic (living organisms)‚ the abiotic (physical and chemical factors)‚ and the interactions made between these. They continually interact with each other‚ thus making complex systems with intersecting properties wherein “everything is connected”. In ecosystem ecology

First Friend: A History of Dogs and Humans‚ by Katherine Rogers‚ articulates the history of the relationship that exists between dogs and humans. Wild Justice: The Moral Lives of Animals‚ by Marc Bekoff and Jessica Pierce‚ investigates if and how dogs exhibit morality amongst each other. In both books‚ anecdotes are used to adequately portray instances of dogs’ displaying cooperation‚ empathy‚ altruism and by extension‚ morality. So from these books‚ how might we describe the capacity for sociality

RESULTS Aphid survival experiment Aphid survival rate varied with both of different combinations of predators-aphids and various times in presence or absence of ants (Table 2). GLM results showed that the interaction of ‘time × different combinations of predators and aphids × ant’ (F = 0.211; df = 10‚ 317; P = 0.995)‚ ‘ant × time’ (F = 0.490; df = 2‚ 317; P = 0.613) and ‘different combinations of predators and aphids × time’ (F = 1.639; df = 10‚ 317; P = 0.095) on the survival rate were not significant

Thank you for inquiring your data to our organization. We have completed an inventory of the biological diversity in Central America and interpreted the distribution of the Choloepus hoffmanni (two-toed sloth) and Bradypus variegatus (brown-throated three-toed sloths). The possible locations the sloths could be located are‚ agriculture (AG)‚ low land old growth (LL OG)‚ low land secondary forest (LL SF)‚ mountainous old growth (MTN OG)‚ mountainous secondary forest (MTN SF)‚ and finally clear cut

EVOLUTION and NATURAL SELECTION (30 pts) a. What is a mutation? Provide 3 examples of different mutations causing specific diseases in human population. For each example explain what kind of mutation that is (ie. A point substitution‚ a chromosomal duplication etc). Mutation is a genetic mistake(s) that occur during DNA replication. 1. Progeria accelerated aging; mutation in the LMNA gene 2. Hypertrichosis excessive hair on the shoulders‚ face and ears; implicate it to a rearrangement
