C. Agar provides a solid surface for bacterial growth.
Agar is a substance obtained from red algae which when added to a culture media, provides a solid surface for the growth of bacteria. When the agar is not added then the culture media remains as the broth and when the agar is added then the broth gets solidified.
Agar is added 1.5-2% in the broth to get solidified. The growth of the bacteria depends on the amount of agar added. Agar is used for the growth of bacteria because it has gel like properties which holds the nutrients evenly and the bacteria can use it accordingly.
A. prevent cross-contamination.
As the bear enters hibernation, its metabolic processes such as body temperature, heart rate, and respiratory rate are reduced. But bears do not lower the body temperature as much as once thought. Their hibernation temperature is around 88 degrees and waking temperature is 100 degrees F. This relatively high sleeping temperature allows bears to become fully alert if aroused, perhaps to enable the bear to protect itself from predators and other dangers without unnecessarily taxing their energy reserves. Over the course of a hibernating season it is thought that bears use approximately 4 thousand calories a day, which results in a weight loss of about 20 percent of it body weight by spring.
Answer:
The pesticides are worn off by the weather.
Explanation:
Becuase the chemicals can only work for a little in the pesticides so when bad weather comes around it finishes the rest of the chemicals in the pesticide.
Hope this Helps :)
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!
