A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms
Explanation:
Carbohydrates are the main energy source of the human diet.
Fats are also a source of energy but fats are the slowest source of energy.
C, triglyceride and cellulose
triglycerides make up lipids. cellulose is not a lipid, but a carbohydrate. carbohydrates are made from sugars :)
I think the answer may be D. But don’t answer yet, I may be wrong.
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.
