Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.
Answer:
They go through many developmental changes. ... Studies by independent researchers show a link between pesticides and frog deformities.

Answer:
A dominant trait is a trait that overpowers, a recessive trait is more rare.
Explanation:
Dominant traits are the most common trait in a pair. They will be seen the most often in offspring. Recessive traits are usually repressed traits that the parents had that were not previously visible
Answer:
The correct answer is A. scavengers and B. producers
Explanation:
Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.
So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.
So both scavengers and producers are living organisms therefore both are examples of biotic factors.
Protein channels + no energy spent + following concentration gradient = passive transport via facilitated diffusion :)
