I think the hydra lacks the specialized cells for touch and chemical detection. On the other hand earthworms have touch, light, vibration and chemical receptors along the entire body surface. Both of them are invertebrates (those animals without a backbone), they include insects, worms, jelly fish, spiders among other animals.
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!
<h3><u>Answer;</u></h3>
Gene therapy to correct defective genes that cause diseases.
<h3><u>Explanation</u>;</h3>
- Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.
- Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.
- The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.
