Answer:
Explanation:
As you probably already know, all of the cells in your body started from a single cell. That single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell
The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences
The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.
Answer:
well you could be aleck and say they are both cells
Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
