Answer:
D.type
Explanation:
<em>FITT principle is a guideline for an effective exercise program depending on the main aim of the program. The F stands for frequency, I stands for intensity, the first T stands for time while the last T stands for type.</em>
Frequency is a measure of how often the exercise is carried out, intensity is a measure of how rigorous the exercise is, time is a measure of the duration of the exercise while type refers to the different kinds of exercise that is carried in the program.
Swimming, walking, jumping, cycling, weight lifting, etc. are different types of types of exercise.
Hence, the choice of swimming instead of walking is an example of type as far as FITT principle is concerned.
<em>The correct option is D.</em>

Answer: The advancement in the science and technology also comes with some of the risks which needs to be maintained at the time of surgery.
Explanation:
The fluoroscopy involves the use of X-rays, a form of ionizing radiation which increases the chances of radiation induced cancer.
Though this risk depends on the risk length of procedure and intensity of rays.
The higher intensity of the rays can also cause burns on the skin which can be equivalent to the sun burns.
The brightness of the screen is also introduced so that the patient is exposed to less intensity of rays.
A tributary is a freshwaterstream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
