MA_775_DIABLO [31]

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

Thepotemich [5.8K]

Answer:

Avirulent.

Explanation:

VIRULENCE is the ability of a pathogenic organism  to infects the host, leading to damages  or death of the host. The extent of these virulent effect depends on  certain chemical substances ( called Virulence factors) produced during the  pathogenic processes.

The virulence effects  is achieved  due to the ability of the virulent factor to disrupt the entire physiological mechanisms of  the organisms; e,g crop plants; though  suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.

In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because

none of the d crop pant is completely diseased.

the nascent intenodes and leaves  are growing to usual size.

Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.

What is the significance of the red blood cell being anucleate?
vekshin1
The red blood cell does not have a nucleus. The lack of nucleus enables the rbc to have more room to contain hemoglobin which increases it's efficiency to carrying oxygen
