Fossils have animals, plants and living organisms imprinted into them, it helps us understand what lived and thrived in certain environments. The age of the rock can also help you understand when that thing lives.I hope this helps!
Answer:
The correct option is A, since if the DNA enters in a circular form it is called a plasmid, and the plasmids upon entering the bacteria self-replicate outside the genetic structure, which gives the bacteria better survival qualities.
Explanation:
Plasmids are generally circular extrachromosomal DNA molecules that replicate and transmit independently of chromosomal DNA, and are normally present in bacteria, archaea, and sometimes in eukaryotic organisms such as yeast. Its size varies from 3 to 10 kb. The number of plasmids can vary, depending on their type, from a single copy to a few hundred per cell. Plasmid vectors allow cloning of exogenous DNA ligands of up to 4 kb since a larger size than this makes cloning in these vectors difficult. The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952. Plasmids can only coexist as one or more copies in each bacterium, due to cell division they can be lost in one of the secreted bacteria.
Answer:
strengths:The cell model shows all the process involved, and it's easy to understand, even if a person isn't familiar with the process
weaknesses: it doesnt show organelle or rna
Decrease as the more frogs there are the more flies will be eaten so that means the flies will decrease.Also if the flie population gets low enough the frog population would shrink too to balance it.
That would be a hypothesis
Hope this helps you :)))
