Which five statements about hemoglobin and myoglobin structure are true? Each hemoglobin molecule can bind four oxygen molecules

, and each myoglobin can bind only one oxygen molecule. Molecular oxygen binds irreversibly to Fe2+ in heme. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent a change in the oxidation state of the iron ion. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron ion. Heme is composed of an organic protoporphyrin component and a metal ion. Each iron ion can form six coordination bonds: One of these bonds is formed between iron and oxygen. Hemoglobin and myoglobin are heterotetramers.

How homologous structures and vestigial structures are evidence of evolutionary relationships.
natali 33 [55]

Answer:

Due to presence of these structures in ancient as well as modern organisms.

Explanation:

Homologous and vestigial structures are the evidences that show  evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.

PLEASE ANSWER ASAP!!!
KATRIN_1 [288]

Answer:

An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess.
