Amino acids are joined by peptide bonds in a polypeptide chain. A peptide bond is one in which the molecules of a carboxyl react with the amino group of another molecule. A molecule of water is then formed and release, leaving the functinal groups to bond together and form a polypeptide chain.
The answer is c ) reservoirs
The third choice is the answer.
This is because chemical change occurs when the (for a lack of better wording) interior of the object is changed in the second one the bread is being broken down chemically by the stomach acid this is because the acid is breaking down the formation of the bread dissolving it and chainring it into something else.
In the 4th one the change that is seen is chemical because the formation of the roof is change the physical appearance may be the same (ie. The size & shape) but their are other changes in the color, texture and maybe taste ( don’t taste a rusting roof lol) these are ways in which you can figure out if a change is chemical or physical.
Physical change occurs when the size and/or shape of an object is changed.
Chemical change occurs when the texture, taste and/or color of the object is changed, but-sometimes chemical change cannot be seen.
Hope this helped :)
D. melting is a phase change from a solid to liquid.
e.g ice melts
Answer:
Fur colour can be represented by both the dominant and the recessive alleles of the gene encoding the fur color.
Explanation:
- Considering that the fur colour trait follows Mendelian laws of inheritance.
- The dominant allele can express itself in both the homozygous and heterozygous condition.
- The recessive allele can represent itself only in the homozygous condition.
- Therefore, there will be two phenotypes, one will be represented by both the homozygous dominant and heterozygous dominant genotypes and the other represented by the homozygous recessive genotype.
- Considering that the fur colour trait does not follows Mendelian laws of inheritance (Incomplete Dominance or Codominance).
- In Incomplete dominance, three phenotypes are observed, for each of homozygous dominant, heterozygous dominant and homozygous recessive genotypes respectively.
- In Codominance, phenotypes of both the dominant and recessive genotype is shown in the same individual.
