It is C, because DNA has 2 pairs: a t and c g.
When translated into RNA, a pairs with u instead.
Difference between plant and animal respiration would be the procurement of glucose and oxygen (for Krebs's cycle). Animals obtain their glucose,by breakdown of carbohydrates in diet,while plants photosynthesize their glucose.
Molecular biology - DNA
development biology - embryo
comparative anatomy - limb of pig and calf
Answer: single- unit smooth muscle
Explanation:
Answer:
Each trophic level represents the beings of an ecosystem and their amount of energy.
Explanation:
In a food chain, the highest energy level is made up of producers (e.g. chlorophyll plants), with the rest of the ecosystem dependent on their energy, captured from sunlight and stored in organic compounds.
The next trophic level belongs to primary consumers (herbivores) and then secondary consumers (carnivores).
From the producers, only part of the amount of energy is passed from one trophic level to the other, In other words, the higher the trophic level, the less energy is absorbed.
In an energy pyramid, each area is represented by a trophic level (from a food chain) of size proportional to its amount of energy.
The elements of the food chain are represented with the producers at the base (higher energy) and the consumers of each trophic level above.
As explained earlier, the amount of energy absorbed at the highest levels is low and therefore insufficient to support another trophic level.
