Charra [1.4K]

A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation.  It can be a deletion, addition or inversion of a single nucleotide base.

In the following, the mutations that occurred are 1. C and 2. B.

<h3>How the mutation can be explained?</h3>

  • <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.

  • <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.

Therefore, silent and nonsense mutations are the correct options.

1-what are three ways organisms deal with limited resources
lys-0071 [83]

1- Animals survive when they compete. In limited resources, animals either compete, kill or co-operat. There are 3 ways animals complete with each other to get access o limited resources. These ways are:

- Parasitism – In this relationship, one animal gets benefit and the other gets hurt.

- Mutualism – in this interaction, both organisms benefits each other and survives.

- Commensalism- In this interaction, one organism gets benefit whereas the other gets nothing in return.

2- Living organisms are classified as:

- Producers

- Consumers  

- Decomposers  

Producers are the energy generators. They are the biggest source of energy for other levels. Consumers feed on producers and other animals. And the end, when consumers die, decomposers feed on them, break down their bodies and mix it with soil increase its fertility and the cycle of energy flow goes on.

Tema [17]

One of the challenges that scientists face when classifying a new fossil is that any tiny detail is all that separates one species from another. Further exploration is required to identify another set of characteristics that may help in deciding which organism belongs or create a new class.
