The correct answer for the question that is being presented above is this one: "broadcasting the very first transatlantic radio signal." Marconi expanded on Morse's invention of the telegraph but he also changed media forever by <span>broadcasting the very first transatlantic radio signal. </span>The first successful long-distance wireless telegraph was created by him.
Answer:
I think the answer to this question is O population, community, ecosystem.
Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
Answer:
The answer to your question is: Synthesis
Explanation:
Synthesis in this reaction tow molecules combine to form a new one.
Decomposition in this reaction, one molecule decomposes to form 2 or more molecules
Single replacement one element replaces another one in a molecule.
Double replacement there is an interchange of elements between two molecules.
Combustion one molecules with carbon, reacts with oxygen to produce carbon dioxide and water.
