Answer:
A
Explanation:
basically, this shows how much energy is consumed the higher up in the food chain you go. Plants/producers would have 100% because that is the maximum amount we can get based on conditions. Not all plants get eaten/ are edible so primary consumers (think bugs, herbivores, etc.) do not get the absolute maximum amount of energy available. This happens again at the next level where not everything is eaten so energy is lost
1- the correct answer is D
2- the correct answer is C
The answer is the relative size and weight of the component.
The resolution of the centrifuge is dependent
on the speed in revolutions per minute. The heavier elements will accumulate at the
bottom of the tube as a pellet while lighter
molecule will be left in the supernatant
Evolutionary adaptations for survival on land produced tetrapods, which later evolved into amphibians, reptiles, and mammals.
Evolution: It can be defined as a natural phenomenon that involves the modifications in physical, biological, and metabolic characteristics of any species which get inherited from one generation to another resulting in better, more advanced new forms of species. This is a very slow process that usually took millions of years to establish a new species from a preexisting one.
The evolution of tetrapods started in the devonian period at around 400 million years ago which are kept under superclass tetrapoda which includes amphibians, reptiles, bird and mammales. The body plan, breathing plan, navigating plan all evolved with time and the tetrapods gets cherecterised into amphibians, reptiles, and mammals.
These facts were estabilished by the transitional fossils collected in late 20th century which are tested and studied on the basis of modern phylogenetic analysis.
