Biology is the study of living organisms. List and describe the seven characterisitcs that most iving things share?
The seven characteristics that most living organisms share is movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. Movement can refer to the ability of an organism to walk or can be less obvious such as plants being able to grow. Respiration refers to the chemical reaction where cells make food from a source of energy. An example of respiration would be a plant performing photosynthesis. They use energy from the sun to make food. Sensitivity refers the ability of an organisms to sense changes within its environment. When it rains plants recognize this and will take up the water molecules in their roots. Growth refers to the ability of all living creatures being able to grow. For example a plant starts as a seed and grows into a flower. Reproduction is the ability of an organism to pass its genetic makeup to their offspring. Many plants use seeds or pollen to spread their genetic makeup. Excretion is the ability for an organism to get rid of waste. Oxygen is created as a by-product of a photosynthetic reaction, this is given off by plants! Nutrition involves the intake and use of nutrients from the environment. Plants take up nutrients when they take vitamins and minerals from the soil around them.
You are working in a clinic and a patient comes to you stating that they were previously diagnosed with a rotator cuff injury. You know exactly what they mean as the rotator cuff is a group of tendons that form a "cuff" over the humeral joint. What four muscle's tendons make up this cuff?
The four muscles the rotator cuff is made up of are the supraspinatous muscle, infraspinatous muscle, teres major muscle, and subscapularis muscle.
