The DNA molecule is very similar among all living things. The pairings are always the same and there are only six components that make up DNA.

Why is there so much diversity of life?

The sequences of base pairs are different.

Organisms use DNA differently.

The sugar component of the nucleotides are different.

Organisms contain different types of DNA.

The correct answer is A.

Explanation:

Though animals may (or probably) be all linked by one source, organisms still have their own types of sequences in their DNA. Because of this, these form different species/organisms in the environment and create variety. For example if the DNA of a Red bird and a blue bird bred, it is possibly that they could create a newer variety of birds that could be a mixed species, having their own type of DNA, that is altered from the red and blue bird(s).

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
