Answer:
Henri Becquerel and the Curies worked with uranium, radium, and polonium, all of which give off radiation.
Explanation:
Henri Becquerel and Marie Skłodowska-Curie discovered the process of radioactivity. They were awarded Nobel prize for their work. Radioactivity is the process in which an unstable element emits energy in the form of radiation. This process also produce a lot of heat. Radiations are very harmful for human health however they have wide applications in modern technology.
I think the correct answer would be the last option. In the lysogenic cycle, viral dna is replicated along with host dna. It is one of the cycles for viral reproduction. It is distinguidhed by the integration of the nucleic acid of the bacteriophage to the genome of the host bacteria.
The mechanisms of evolution allow evolutionism to be explained according to the scientific method. Through the mechanisms of evolution we can understand how the equilibrium in a population is changed and the consequences that this change causes.
The most important mechanisms of evolution include:
- Trial and error: It is the simplest of all methods of evolutionism; in principle it is typical of microorganisms with a lot of progeny in each generation and relies on the later mechanism of natural selection.
- Natural Selection: In the strict and exclusive sense, it would act as the only method of effective evolution, since random modifications alone would not achieve the observed evolution of living beings. Assuming the randomness of modifications, the earlier trial and error method would be more general than natural selection, since it does not always operate. Natural selection is characterized as a method of verification exogenous to the evolutionary system itself or the system of creation of genetic modifications, as it acts “a posteriori”.
- Exhaustive proof or simulation: Of the results predicted by the genetic modifications made. In certain cases, living organisms may prove the effect of replacing, for example, one protein with another, if the evidence is satisfactory with respect to the functionality of the new mechanism of evolution; and there is no risk of having side effects on suppression of the first protein, genetic modification could be carried out without major problems as the guarantee objective would be fully covered.
- Partial Proof of Modifications: When an evolutionary system is complicated and contains many interrelationships, exhaustive proof of the effects of a small modification will not be possible and will have to be limited to more or less extensive but not total proof. To the extent that the range of possible effects of genetic modification has been covered, it will carry greater or lesser risk. The risks of this method are very well known to computer programmers.
Answer:
The correct option is <u>A. It will soon start to grow.</u>
Explanation:
In biological terms, a food chain can be described as a linear representation of energy flow in an ecosystem. It usually starts with the producers and then represents a chain until the decomposers.
A change in any of the species population of the food chain can affect the food chain widely. For example, in the question above, <em>as the population of algae increases, the population of minnows will also increase. This is because there will be more supply of food for the minnows.</em>
The food chain would most likely collapse slowing, without a producer other animals cannot get the needed nutrients required to survive.
