Can you think of a real-life example of how man-made pollution affected a real ecosystem, its abiotics (e.g. temperature, water

quality, etc.) its biotics (e.g., species extinction), or its habitat?

Answer:

Nigeria Niger Delta Community

Explanation:

Human activities in the form of man-made pollution has had an almost irreparable condition to the ecosystem, abiotics, biotics and habitat of the Niger delta region of Nigeria, West Africa.

These activities has brought an end to the rich fish species in this region, it has destroyed completely the marine life. Some species of birds are no more. Obviously, the soil is destroyed, it's micro organism and nutrients levels are all gone.

Some of such activities that has led to this destructive situation includes:

1.  Natural Gas Flaring

2. Depletion of Aquatic stability

3. Oil Spillage

4. Destruction of Mangrove forest etc.

Answer:

1) Toxic gases released from the exhaust of cars into the atmosphere can pollute the environment and habitat.

2) Improper disposal of waste or sewage, which ends up in the soil, streams or rivers where human get drinking water and it can even pollute the atmosphere too.

3) Spillage of oil which can enter the rivers

4) Burning of clothes, tires and other materials that release black smoke, carbon monoxide and other harmful gases.

Chronic exposure to nicotine desensitizes _______ receptors in the midbrain.
Nikitich [7]
<h2>Nicotinic ACh</h2>

Explanation:

  • They serve differing and regularly basic capacities all through the focal and fringe sensory systems, and have developing jobs in non-neuronal systems, .  
  • The synapse acetylcholine (ACh) can direct neuronal edginess by following up on the cys-circle cation-leading ligand-gated nicotinic ACh receptor channels (nAChRs).
  • These receptors are broadly disseminated all through the focal sensory system, being communicated on neurons and non-neuronal cells, where they take part in an assortment of physiological reactions, for example, uneasiness, the focal handling of torment, nourishment consumption, nicotine looking for conduct, and psychological capacities.
  • In the mammalian cerebrum, nine distinct subunits have been discovered up to this point, which amass into pentameric edifices with much subunit decent variety; anyway the α7 and α4β2 subtypes prevail in the CNS.

At one time, membrane biologists thought that transport proteins might act by binding a solute molecule or ion on one side of th
Ivahew [28]

Answer:

The process of passage of different molecules, solutes, and liquids, through the phospholipid bilayer in human cells, and really in all animal cells, is highly dependent on a tight coordination between chemical, and thermodynamic balances, that will collaborate in these elements being able to pass, or not pass, through a cell´s membrane, and activate other mechanisms within the cell when their passage is not possible. Unlike what was once believed, that transport proteins were like buses parked at the membrane and waiting to be loaded with molecules to later remove themselves from the membrane and carry their load into the cytoplasm, scientific research has found that this is definitely so, and that transport proteins do not come off the layer to transport  molecules. They are permanently anchored to the membrane and through a series of second messenger systems, energy produced by the passage of certain ions like potassium and sodium, and other such processes, these transport proteins become activated, allow the passage of molecules and change them in such a way that they can be taken into the cell in vesicles, or, they will anchor them to second messengers, who will be responsible for carrying the molecule inside.

From the list of words given and the two sentences down below, which are two reasons why the earlier believed models for transport proteins are not correct would be:

1. Integral membrane proteins are embedded stably in the membrane and protrude from one or both side based on their hydrophobic, or hydrophilic, regions. These sides will not switch because of the disbalance that would be created if the two sides had to be switched chemically to allow them to pass to the opposie sides.

2. For protein to traverse a membrane, movement of its hydrophilic regions through the interior of the membrane would be required, which would be highly endergonic and hence thermodynamically improbable.

2. Nitrogen, as it is found in the ATMOSPHERE, can be used by plants and
irina1246 [14]

Answer:

false

Explanation:

Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
