I would say the correct answer is B: <span>People tend to overuse or degrade shared resources. It is often not clear how much exploitative pressure a natural resource can sustain before the exploitation becomes unsustainable. So for example, various industries may dispose of waste into a river. The river has a capacity to absorb and clean a certain amount of effluent by natural degradation systems. However, at some critical mass of pollutants, these natural processes are no longer able to function properly, and the river becomes very polluted to a point were the resource cannot be utilised. Monitoring can help to gauge at which point a common resources is becoming unacceptably degraded, and this can guide policy.</span>
Adenohypophysis, and nerohypophysis.
Explanation: Adenohypophysis (anterior lobe) derived from buc cal ectoderm. Nerohypophysis (posterior lobe) is also called pars nervosa derived from neural ectoderm.
Answer: D. manipulating the DNA of cats.
Explanation:
Deoxyribonucleic acid (DNA) refers to the organic chemical which consists of genetic information. The DNA can be found in the cells of organisms.
Since the new line of cats are genetically modified to eliminate or reduce their allergy-causing properties, then we can infer that the DNA of the cats have been manipulated. In this case, the allergy causing property won't be passed across to the offspring since the DNA has been manipulated.
Answer:
I think the amount of atmospheric CO2 has increased in the last 550 million years.
Explanation:
Carbon dioxide creates greenhouse gases heating up our atmosphere and climate. Since the CO2 is rising, our planet is heating up, global warming, and one effect of that has been the ice caps melting..
Answer:
>>>steady nutrient supply
>>>>ample sunlight
Explanation:
The neritic zone lies in the continental shelf and it extends from the surface to about a depth of 200m. Below the neritic zone is the bathyal zone.
The neritic zone is a shallow zone of water. It is sunlit and it receives ample solar insolation all year round. The salinity of this zone is very stable. This makes for organims to thrive. The neritic zone is home to diverse aquatic life. Due to the ample sunlight available here, photosynthetic rate is very high.
Due to high insolation in this region of the ocean, surface temperature is very high. The deeper we move in the ocean, the colder the water body becomes.
