Answer:
a rat with rabbit hemoglobin genes
Explanation:
When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.
This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.
Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.
Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.
Genetically modified bananas as edible vaccines are another example

Answer;
Volcanic eruption.
Explanation;
Primary succession is most likely caused by volcanic eruption.
it occurs in lifeless areas; such as regions in which the soil is incapable of sustaining life as a result of factors like lava flows, newly formed sand dunes, or rocks left from a retreating glacier.
The other type of succession is called secondary succession which occurs as a response to disturbance; such as forest fire, tsunami, flood, among others.
