If fertilizers enter the St.Johns river they will result in nutrient overload, or eutrophication and harming the ecosystem of the river. The river will exceed its assimilative capacity for nitrogen and phosphorus. this will <span>deplete oxygen in the water needed by fish and reduce light that is essential to submerged vegetation. </span>
Answer:
The pressure of a given amount of gas is directly proportional to the temperature at a given amount of volume. When the temperature of a system goes up, the pressure also goes up, and vice versa.
Explanation:
This occurs because of the pressure temperature law. (or also known as the Gay-Lussac's law)
<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>
Answer: A.it is a relatively new human adaptation.
Explanation:
Fight or flight response is a response shown by a human or animal body towards acute stress. It is a physiological reaction that occurs in response to the perceived attack, survival threat and attack. The animals or humans react to threats by the hormonal secretion from sympathetic nervous system. This prepared animals for fighting. The hormonal secretions like catecholamines, epinephrine and nonepinephrine helps in generation of response. Neurotransmitters dopamine, estrogen, testosteron e and cortisol affects how organisms react to the stress.
Fight-or-flight reaction is not a relatively new human adaptation but it is evolved as a survival mechanism which was also present in primitive human beings and mammals and helped them to react in the life-threatening situations.
