Answer:

Professor Kwang Jeon observed that some amoebas in his invaded amoeba colonies survived because of the changes made by the invading bacteria. This verified the endosymbiotic theory that organelles are regularly invading free living prokaryotes forms that were integrated and swallowed by others to create a new living unit.

Use the original DNA sequence above to write an example of each of the following types of mutations: insertion, substitution, an

Tanya [424]

For example: GGATACCTAGGTAAT

Insertion: GGATGACCTAGGTAAT

a nucleotide that was not present before is inserted into the original sequence

Substitution: CGATACCTAGGTAAT

the first nucleotide was substituted in for another (C for G)

Frameshift (basically a insertion or deletion, we'll try deletion here): GATACCTAGGTAAT

the first nucleotide was deleted, causing the reading frame to be shifted (instead of GGA as the first codon, we have GAT)

natta225 [31]

Answer:

Plants

Explanation:

They are multicellular organisms. In plants there are two types of reproduction :- sexual and asexual. Sexual reproduction happens when androecium and gynoecium both fuses and in asexual reproduction when only androecium or gynoecium is present in a plant. Androecium us a male part off flower and gynoecium is the female part of flower. Plants can't move that we all know and they are autotrophs coz they can make their own food in presence of sunlight, water, air and chlorophyll.....

I hope u will understand it :-) :-)
