Which indicators are living and non-living?

Biology
1 answer:
bulgar [2K]3 years ago
7 0
Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.

Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.

Because it is difficult to excrete iron once it is in the body, iron balance is maintained primarily through absorption. The iro
Rzqust [24]
<h2>The given statement is true</h2>

Explanation:

Iron absorption occurs in the duodenum and upper jejunum of small intestine

  • At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
  • Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
  • Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
  • Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
  • Transferrin is the major iron transport protein which transports iron through blood
  • Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
  • Fe2+ needs to be oxidized first so that it can be transported through ferroportin
  • Once iron gets inside the cell it can be used for various cellular processes

EXPLAIN The scuba diver is a living system. The scuba gear, or self-
zepelin [54]

Pt.I

All living things needs some form of oxygen to live. In talking about a scuba diver, we are talking about a human, who uses their lungs to breathe, and did not develop the ability to breathe under water. Instead, when in a body of water, we tend to hold our breaths until an opportunity arises for us to exchange our carbon dioxide for oxygen.

Take into account the scuba gear. The scuba gear fits the user, and has a number of protection, including the suit counter-balancing any pressure applied by the deep, and the tank providing much needed oxygen to the user during delayed periods within the water.

Pt.II

<u>How does these two systems interact?</u>

Like as a human is breathing on land or even swimming, the human expels carbon dioxide, which forms into "air bubbles" that are then expelled into the water surrounding. The user then draws air from the pressurized air tank, and is able to breathe as such. This allows the user to stay underwater for much longer than just one breathe, and is able to travel farther inside the deep.

Inside this system, the Oxygen is first input into the oxygen tanks, which are then used by the diver. The diver would draw the oxygen from the tank (output), and he will then expel the used air into the surrounding water.
