Answer:
B
Explanation: I’m just using common sense. If part of the prairie grass is destroyed, that would mean less food for the bison. Which in turn would result in a decrease of Bison?
Growth hormone encourages the growth of bone and cartilage during this stage of development. Growth hormone controls various parts of human metabolism, including insulin activity and blood sugar levels, as well as the fat, muscle, tissue, and bone in our body.
For example, hormones tell the body when to grow and when to stop growing. These hormones circulate throughout the body and work with other cells to coordinate and regulate a variety of bodily functions, including controlling mood, growth and development, tissue function, metabolism, sexual function, and reproductive processes.
Growth hormone-releasing hormone (somatocrinin) and growth hormone-inhibiting hormone (somatostatin), both of which are secreted by the neurosecretory nuclei of the hypothalamus, regulate the release of growth hormone.

Answer:
Seasonal fluctuations in water availability cause predictable changes in the profitability of habitats in tropical ecosystems, and animals evolve adaptive behavioural and spatial responses to these fluctuations. However, stochastic changes in the distribution and abundance of surface water between years can alter resource availability at a landscape scale, causing shifts in animal behaviour. In the Okavango Delta, Botswana, a flood-pulsed ecosystem, the volume of water entering the system doubled between 2008 and 2009, creating a sudden change in the landscape. We used African buffalo (Syncerus caffer) to test the hypotheses that seasonal habitat selection would be related to water availability, that increased floodwater levels would decrease forage abundance and affect habitat selection, and that this would decrease buffalo resting time, reduce reproductive success and decrease body condition. Buffalo selected contrasting seasonal habitats, using habitats far from permanent water during the rainy season and seasonally-flooded habitats close to permanent water during the early and late flood seasons. The 2009 water increase reduced forage availability in seasonally-flooded habitats, removing a resource buffer used by the buffalo during the late flood season, when resources were most limited. In response, buffalo used drier habitats in 2009, although there was no significant change in the time spent moving or resting, or daily distance moved. While their reproductive success decreased in 2009, body condition increased. A protracted period of high water levels could prove detrimental to herbivores, especially to smaller-bodied species that require high quality forage. Stochastic annual fluctuations in water levels, predicted to increase as a result of anthropogenically-induced climate change, are likely to have substantial impacts on the functioning of water-driven tropical ecosystems, affecting environmental conditions within protected areas. Buffer zones around critical seasonal resources are essential to allow animals to engage in compensatory behavioural and spatial mechanisms in response to changing environmental conditions.

No. Glucose is split by glycolysis before the aerobic parts of cellular respiration, when oxygen enters the process.
