Please select the best answer from the choices provided.

Answer:
False. During physical exercise the oxygen concentration in the blood remains the same, with regard to rest.
Explanation:
In a healthy person, the concentration of oxygen —also called O₂ saturation— in arterial blood is in the order of 97 and 100%, both at rest and during exercise.
The concentration of oxygen in blood is a parameter that depends on proper respiratory function, and varies according to whether the blood is arterial or venous, where this percentage is lower.
The O₂ saturation in arterial blood allows to know the amount of oxygen that reaches the tissues and it is not a parameter that is modified with the exercise, although the respiratory and cardiac frequencies increase.

Answer:
The answer is
* they are eukaryotic
* they contain chloroplasts

Hope I helped!!!
Explanation:
Plant cells are eukaryotic organisms. They have some features which makes them unique from other organisms. These include presence of chloroplast, immobile nature, and autotrophic mode of nutrition. Thus, the correct options are B, C, and D.
What are plant cells?Plant cells are the multicellular eukaryotic organisms. These are eukaryotic as they contain double-membranous structures and a well-defined nucleus.
Plant cells contain chloroplasts which perform photosynthesis. Photosynthesis is the process by which plants synthesize their own food by the help of sunlight, carbon dioxide and water. Chloroplast is absent in animal cells.
Plant cells are immobile because they do not have any locomotory organelle on their surface which can cause movement. Plants are anchored deep into the soil with the help of their roots.
Plants show autotrophic mode of nutrition as they can prepare their own food by the method of photosynthesis.
Therefore, the correct options are B, C, and D.
