Answer:
circulatory and respiratory
Explanation:
The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.
When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.
Thus, circulatory and respiratory is the correct answer.
In chickens, the black wing allele is co-dominant with the white wing allele. Black and white birds are homozygous for the black (B) allele or the white (W) allele.
In genetics the terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are being expressed separately to produce the different traits in the individual. In perfect dominance, only the one allele of the genotype is also present in the phenotype. In codominant cases, both the alleles of the genotype are present in the phenotype. In the case of the imperfect dominance, the phenotype shows the mixture of genotypic alleles. In the genetics terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are expressed and separately to produce the different traits in the individual.

Answer:
All given options are correct.
Explanation:
Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.
The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.
Thus, all the given option are correct.
