1. An organism with only one kind of enzyme (two alleles that are the same) is said to be what?

2. An organism with two different versions of one kind of enzyme (two alleles that are not the same) is said to be what?

3. What kind of biomolecule is hemoglobin?

4. Explain the difference between Hemoglobin A (Normal) and Hemoglobin S (sickle cell) in terms of their chemical structure and resulting function.

Please explain as detailed as you can

Homozygous, Heterozygous, Protein sub u its

Explanation:

When two alleles are of the same it is said to be homozygous.When two alleles are different, it is called heterozygous.Hemoglobin gives red color to the blood.  It is composed of four protein chains, two alpha chains and two beta chains. The oxygen is transported through the blood. Each of the protein chains is similar in structure to myoglobin, the protein used to store oxygen in muscles and other tissues. In sickle cell the red blood cell is in the form of a sickle and the hemoglobin count reduces.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
