Hello There!
-There are 2 possible ways that a pond could form-
The first way it could happen is because of erosion. Erosion is the movement of weathered materials. This includes gravel, soil, and sand. This is the reason why the Earth's surface is always changing.
The second way ponds could made is by a person. This is called man made because someone had to be able to build hem
The answer would be mouth and stomach
The answer is (d.) Some scientists believe that prions, tiny proteins much smaller than a cell, that can replicate themselves may be living organisms.
Prions are like viruses, they are not alive making statement B to be true. Prions lack the ability to grow and reproduce. they are dependent on the living cells to replicate. Statement A is absolutely correct while Statement C is somehow wrong. According to scientists, the accurate count of cells in a human is 37.2 Trillion.
Henry observed the aquatic life in the pond, but also the
trees, vegetation, and animal’s species on land. The diversity observed by
henry is ecological diversity. Ecological diversity is the variation in the
ecosystems found in a region or the variation in ecosystems over the whole
planet. Ecological diversity includes the variation in both terrestrial and
aquatic ecosystems.
Firstly, we need to know what a healthy ecosystem is. When an ecosystem is healthy, this would mean that it could supply all the resources that all organisms present in it and with all the resources, there is diversity. Old growth forests are considered healthy because of this reason. These forests remain untouched and had remained in providing the resources needed for the organisms present in it.
