Answer and Explanation: Nondisjunction occurs when sister chromatids are not pulled apart at anaphase II. This will cause both sister chromatids/ homologous chromosomes to be pulled to just one pole of the cell.
Since the anaphase I stage in Meiosis I occurred without errors, this would result in four haploid gametes being produced.
However, two of these gametes will be normal, will have the normal number of chromosomes. The other two gametes would have an abnormal number of chromosomes and be aneuploid. One would have n+1 number of chromosomes, and the other would be n-1.
Answer:
Hemoglobin.pulmonary artery.
Explanation:
1. about hemoglobin.Hemoglobin is the protein inside red blood cells. It carries oxygen.
2. about pulmonary artery.The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
3. There exist a concentration difference of carbon dioxide and oxygen inside the alveoli and capillaries due to which the diffusion of the two gases takes place. The carbon dioxide moves from the blood to the alveoli sac and the oxygen moves from the sacs to the blood.
The scientific method's foundation is best described as "the process of hypothesis and testing through which scientific inquiry happens." Thus, the correct option is D.
<h3>
What is scientific method?</h3>
The scientific method is a set of actions that are followed in order to develop scientific knowledge.
The scientific process includes the following steps:
- To make observations on a particular natural occurrence and then generate questions based on those observations.
- To answer these questions, you must propose a credible explanation (i.e., a hypothesis).
- To put the working hypothesis to the test using experimental and/or observational methods.
- To gather information in order to confirm or refute a working theory.
- Analyze the findings and develop conclusions.
