The right answer is: An organism's characteristics are determined by their genome which is inherited from one generation to the next.
We can give some characteristics of a living organism:
* The ability to stay alive by drawing energy and necessary components into the environment. This ability is based on the metabolism that includes various functions, such as nutrition, respiration, photosynthesis ...;
* The ability to develop according to a certain organization (growth, morphology, cell division, development);
* The ability to reproduce and give birth to other living organisms (vegetative or sexual reproduction);
* The need for a favorable environment to survive (temperature, pressure, oxygen, water ...).
Living matter is based on organic chemistry based on carbon.
Answer: The surface water is usually saturated with oxygen, absorbed from the atmosphere and from photosynthesis of algae. In the deep water the oxygen is consumed when breaking down the organic matter that sinks from the surface. ... In areas with poor water turnover the oxygen in the deep water can become completely used up.
Explanation:
Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
Isobars. Like for the barometro the term bar indicates the measurement of pression. Iso stays for "the same" (like isoscele=same sides)
