Answer:
miRNAs are short sequences of RNA (20-24pb) with high self-complementarity, allowing it to fold over itself (hair fork structure). This makes miRNA super stable, even in the highly reactive atmosphere of the cytoplasm.
miRNAs do not have RBPs as in RNAm. They are linked with different proteins of the post-transducer machenary, such as argonaute, DICER or others, to serve as a guide to the adequate protein complex.
A monohybrid cross only involves one trait, for example "shape". A dihybrid cross involves two traits, for example "shape " and "height".
Answer:
In the freshwater food web,
the relationship between the minnow and the water fleas can be described as <u><em> Predator-prey relationship</em></u>
Explanation:
A food web can be described as a diagram which shows multiple food chains. It represents the 'predator-prey' relationship in an ecosystem.
The freshwater food web will described all the predator-prey relationships in the fresh water.
The minnows in the fresh water feed on larval fishes, mosquito larvae and water fleas. Hence, minnows will be the predators and water fleas will be the preys. So, these organisms will show a predator-prey relationship.
For example, an internal combustion engine converts the potential chemical energy in gasoline and oxygen into thermal energy which, by causing pressure and performing work on the pistons, is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy).
I hope this is what you need. :)
