It is important to identify compensations seen during the modified thomas test because option D: most people have short/stiff anterior hip muscles.
The modified Thomas test measures the femur's angle of abduction in relation to the pelvis, which is an objective measure, and the pelvic position is constant when comparing results from one test to another. The lower extremity on the concerned side won't be able to stretch all the way at the hip if the iliopsoas muscle is short or there is a contracture. This results in a favourable Thomas test result. This therefore, implies that option D is the right choice.
A psoas dysfunction may occasionally coexist with a very flexible patient's Thomas test being normal. However, a positive test is a good indication of psoas hypertonicity in the patient with a normal hip joint.

Light dependent reactions require an actual source of light, and this is from the sun, for energy to carry out the first stage of photosynthesis. They need solar energy to split a water molecule in order to obtain electrons from hydrogen to be used in fueling photosynthesis.
Light independent reactions do not require a light source for energy but rather they use energy that was created by the light dependent reactions to complete the process of photosynthesis in which different carbohydrates for the plant are made.
Cells provide structure for the body. They take in nutrients and convert it to energy as well.
B is correct.

Answer:
C
Explanation:
Ammonia is toxic to the body. Animals that live in water excrete their waste in ammonia (aqueous) form because it is less toxic when diluted. However, land animals need to convert the ammonia to a less toxic product such as urea before excretion. Ammonia is formed through deamination of amino acid.
