Answer:
Due to the presence of limited number of species.
Explanation:
Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.
Answer:
1) IRIS
2) LENS
3) RETINA
4) Fovea Centralis
Note: Answers 1 - 4 follows question pattern
Explanation:
The PUPIL is the hole in the MIDDLE of the IRIS of the eye, through which light passes to be focused on the RETINA.
The IRIS is the contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
ACCOMMODATION is the change in the adjustment of the eye lens to help focus light ray.
RETINA helps to receive light rays that the lens has focused. It contains two cells: rods and cones
Fovea Centralis is at the center of the retina responsible for sharp and accurate vision, also it is where cones cells cluster.
The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ = 
(for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ = 
(for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
