And increase in food and a decrease in predators would most likely

Answers

An increase in food and decrease in predators would most likely create a habitat that would be over run by animals. Without predators these animals will take over the area and become a nuisance to people and other animals in the area. One example would be the starling in New York city. They were released in Central Park and had no natural predators so they became to flourish and would invade and take over the area from other birds.

Which statement supports the modern extension of the cell theory that states "all living cells come from preexisting cells"? a. All living organisms are multicellular. b. Cells pass on hereditary information. c. Each cell in an organism contains a single nucleus. d. The chemical composition of cells varies by organism.​

Answers

The statement that supports the modern extension of the cell theory that states "all living cells come from preexisting cells" is that they pass on their genetic information. Option B is the correct answer.

What is the presence of nucleus like ?

The presence of nucleus is like the central position in which all the machinery of the cell parts are all included.

All organisms only  inherit genetic information just by  specifying the structure and the  function from parents.  In that case , all  the cells that  arise from the type of the preexisting cells such that  the genetic material needs to be replicated along with passing  from  the parent to the  progeny cell in each  of the cell division.

DNA, or  the deoxyribonucleic acid in which it is hereditary material in  the humans and all  the other organisms.  Nearly every cell in  person's body is having same kind of DNA. A sperm and egg each of them just  contain  a set of  the total pair of 23 chromosomes. When sperm fertilises egg,  then the two copies of chromosomes  are just  present and an embryo just  forms up.

What does "all living organisms have a universal genetic code" mean

Answers

Well allliving organisms contain genetic information, stored in DNA and RNA molecules,which directs the functions of cells. 

The general coding and structureof these molecules is universally shared by all organisms. Questions about theorigin of these molecules are fundamental to our understanding of the origin oflife on Earth.

Experimentslike the one conducted by Miller and Urey demonstrated that organic moleculescould have formed spontaneously in Earth's early atmosphere, and smallermolecules could bond together to build large organic molecules. Somescientists hypothesize that some of the first large organic molecules to formand self-replicate were RNA molecules, with DNA molecules forming much later. This is called the RNA worldhypothesis.

These early RNA molecules were probably smaller than the RNAmolecules in our cells today. They would have contained the codes for buildingspecific protein molecules from the amino acids present on Earth at that time.Proteins are necessary components of all living cells.

It means that all of us- every living creature- was built off the same genetic code.
