The correct answer is B. Vitamin A.
Vitamin A (retinol, retinoic acid) is a fat-soluble vitamin important for vision, growth, cell division, reproduction and immunity. It also has antioxidant properties.
Vitamin A is present in many foods, such as spinach, dairy products and liver. Other sources are foods rich in beta-carotene, such as leafy vegetables, carrots and cantaloupe. Your body transforms beta-carotene into vitamin A.
There are two dofferent types of vitamin A. The first type, preformed vitamin A, it is found in beef, poultry, fish and dairy products. The second type, provitamin A, is found in fruits,vegetables and other products of vegetable origin. The most common type of provitamin A present in foods and dietary supplements is beta-carotene.
Not consuming enough vitamin A, can cause diseases (which can be avioded with a good diet). Vitamin A plays a very important role in vision. On the one hand, it is essential for the production of the pigment consumed by photoreceptors responsible for vision in darkness. Therefore, low levels of vitamin A lead to night blindness.
Answer:
Science is a system of body of knowledge that contains established truths based on observation of facts by empirical means, collection of such data, theorizing on that basis, do experiments on the data, repeat the experiments under different data of similar nature, once confirmed, make it a law.
So you can define science as logical construction of empirical data. The principles involved is the principle of verifiability, confirmability, conformability and falsifiability. Science is always opne and subject to correction by new observations. If there is a dispute between a Law already established and a new observation, the new observation will replace even the law for rejection or modification.
Theology is a study of God, beliefs and the relationship between God, universe, our knowledge and man's link with all these issues. It is a rational way of studying religious ideas. For example, we talk about Christian theology. It is more concerned with our beliefs mostly unquestionable in principle. they are more like axioms. You can say that they are self evident truths which do not require any proof.
Explanation:
Theology can use the principles and methodology of science to establish some of its tenets. But generally, theologians claim that their system falls outside science and it is supra science and science is too little or limited with its rusted tools to examine and verify Theological doctrines.
Science does not need theology nor the other way round, but man needs both. 60% of the total population believe in god and 40% are non-believers in the sense some are irreligious and some are anti-religious and some NOTA category. But all of them, in some sense, get some "religious" anxiety, when during a flight take off, if there is turbulence at the tail end of the flight!
