Ecology is the study of how organisms interact with one another and with their physical environment. The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, nonliving or physical, factors. biosphere
The broadest, most inclusive level of organization is the biosphere. This includes both biotic and abiotic components of the earth and the part of the atmosphere that supports life. biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors. Ecology studies the interactions between biotic factors, such as organisms like plants and animals, and abiotic factors. For example, all animals (biotic factors) breathe in oxygen (abiotic factor). All plants (biotic factor) absorb carbon dioxide (abiotic factor) and need water (abiotic factor) to survive. Abiotic factors are the non-living parts of an environment. These include things such as sunlight, temperature, wind, water, soil and naturally occurring events such as storms, fires and volcanic eruptions. Biotic factors are the living parts of an environment, such as plants, animals and micro-organisms. An organism is made up of four levels of organization: cells, tissues, organs, and organ systems. These levels reduce complex anatomical structures into groups; this organization makes the components easier to understand.
Destruction of neurons in the hippocampus as a result of stress can lead to problems with long term shrinkage of hippocampus.
<h3>What is the impact of stress on hippocampus ?</h3><h3 />
The hippocampus is the central organ of learning located near amygdala of the mid-brain.
It convert the working memory into long-term form memory for storage.
During stress, our brain wants to focus on sensory stimuli and quick problem-solving which resulted in alteration of function in hippocampus
Both acute and chronic stress causes less functionality of hippocampus
stress alters synaptic plasticity and firing properties of hippocampal neurons, changes neuronal morphology, proliferation and reduces hippocampal volume.

Answer:
Cohesiveness, adhesiveness, and surface tension: would decrease because without the +/-‐ polarity, water would not form hydrogen bonds between H20 molecules. As a result, water would not “bead” up (skcking to itself), or suck to other surfaces well, or form surfaces that can support small amounts of pressure.
