Answer:
New species can appear gradually through small changes in an ancestral species.
Explanation:
The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
Answer: When the plant has enough water in its cells the guard cells swell up and open the stomata. When the plant isn't getting enough water the guard cells can't swell and the stomata stay closed, so the plant doen's lose water. But if the stomata are closed photosynthesis can't happen and eventually the plant might starve.
Explanation:
we use the model to learn about how to create new things
Hello!
RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.
RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.
Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information.
Have a nice day!
