"Scientific knowledge builds upon previous knowledge."

1 answer:

5 0

<span>The answer is C. This is because the discovery of the cell and its organelles began with the discovery of the microscope in the 17th century. As powerful microscopes were developed over time, the cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of elements, hence monitoring of biochemical pathways also became possible.</span>

Why do we classify organisms??

OLEGan [10]

Answer: we classify organisms to group living beings who share the same characteristics or who have common attributes

Explanation: So, since the late '60s and based on the proposal of the researcher Robert Whittaker, most biologists group living beings into 5 large groups called Kingdoms, based mainly on three characteristics:

* type of cell,

* number of cells in each organism and

* the way of obtaining energy.

As a result, we could have 5 kingdoms; and these kingdoms are:

Monera, represented by the microorganisms of prokaryotic type known colloquially as "bacteria"

-Fungi, represented by mushrooms

-Plantae, the kingdom of the plants

-Animalia, the kingdom of the animals, and

-Protist, a very diverse group of organisms of eukaryotic type.

Which is an example of a substitution mutation?

Marta_Voda [28]

Answer:

CAT - GGC - TAC mutates to CAT - GGC - TAG

Explanation:

Changes occur in the nucleotide sequence of the DNA molecule. These changes referred to as MUTATION are usually due mistakes during DNA replication or induced by mutagens (mutation-causing substances). Mutation can be of different types depending on the kind of change that occured to the nucleotide sequence. Based on this question, one of the mutation types is SUBSTITUTION MUTATION.

Substitution mutation is a kind of mutation in which one or more nucleotide base replaces another in the sequence.

The option that suits an example of substitution mutation is: CAT - GGC - TAC mutates to CAT - GGC - TAG because Guanine nucleotide replaces Cytosine nucleotide in the third CODON i.e. TAC becomes TAG.
