Answer:
Like hot springs and geysers on land, hydrothermal vents form in volcanically active areas—often on mid-ocean ridges, where Earth's tectonic plates are spreading apart and where magma wells up to the surface or close beneath the seafloor.

Answer:
Fermentation is important can keep obtaining energy from glycolysis.
Explanation:
In the presence of oxygen, cells will use aerobic respiration to obtain energy in the form of ATP. In these conditions, it can produce up to 36 ATP molecules.
This process has three steps: glycolysis, citric acid cycle and electron transport chain.
During glycolysis, a glucose molecule is broken down into two pyruvate molecules, releasing electrons that are taken up by NAD+ which is converted into NADH, and producing a net total of 2 ATP molecules. The NADH produced during glycolysis and the citric acid cycle will go to the mitochondria and give away the electrons to start the electron transport chain that has Oxygen as the last electrons acceptor, and the NAD+ used to continue glycolysis is regenerated in the process.
In anaerobic conditions (no oxygen), the last electron acceptor is scarce, so the NADH can't give away its electrons and the NAD+ cannot be regenerated, so glycolysis stops, eventually causing cell death due to lack of ATP. To avoid this, cells perform lactic acid fermentation, where the NADH gives the electrons to pyruvate which is then converted into lactic acid. This regenerates the NAD+ necessary to continue glycolysis and keep obtaining some energy to survive until oxygen levels increase.
The correct answer is "securing the airway and providing ventilation".
It has been proven that the first priority when dealing with drowning victims is to try and resuscitate the victim. This is done by securing the airway and providing ventilation. Especially, in this prehospital stage, the first responders should assess the airway, breathing, circulation and cervical spine. After securing that the victim has normal breathing and circulation, the healthcare professional should focus on correcting any abnormal physiological functions, such as hypoxia and hypothermia.
<u>Answer:</u>
<em>Warm water </em><u><em>is less dense than cold water and has lower salinity than cold water.
</em></u>
<u>Explanation:</u>
When the <em>temperature of water increases</em> the freedom movement of molecules increases and they expand. Hence the space between the molecules increases thereby causing the liquid to occupy more volume. Density is <em>the ratio of mass and volume</em> which means an increase in volume will decrease the density of a liquid.
Thus an increase in temperature has a negative impact on density and the density decreases. Salinity tends to increase with density. Thus temperature has a negative impact on salinity as well. When <em>temperature increases salinity decreases.
