Which is a disadvantage of the genetically engineered potatoes

Answers

Answer 1

Answer:

The question lacks options, the options are:

A) They are easier to transport and store than injectable vaccines (shots).

B) They make it easier to administer edible vaccines.

C) They are more expensive than potatoes without the vaccine.

D) They have nutritional value while potatoes without the vaccine do not.

Thw answer is C

Explanation:

Agricultural crops have faced series of problems caused by pest, nutrient composition etc. However, technology has made sure they these problems are reduced in the least possible way via the use of genetic engineering. Genetic engineering, also called genetic modification is the manipulation of an organism's genes using biotechnology procedures.

In this case, the potato crop was genetically modified, meaning that, the crop was improved genetically. Although, this process has many advantages like inserting a vaccine in the edible crop and easy storage, it also has disadvantages. One of these disadvantages as mentioned in the options is that they become more expensive than potatoes without the vaccine. The price increases due to the vaccines they now contain in comparison to the potatoes without vaccine (not genetically modified).

This price can become not affordable for an average person. Hence, it is a disadvantage of the genetically modified potato crop

Answer 2

Answer: Disadvantage:
1. Cause health problems for animals eating the product.
2. Some GM foods may contain allergens and toxins.
3. Gene transfer may occur between organisms.

Impala share the African plains with other grazing animals and predators. Which change would lead to a DECREASE in the impala population?

Answers

So, the Impala share their food with other grazing animals. These animals are their competition.

If there is an increase in the competition, that is in the number of other grazing animals, such as other species of antelope (Impala are antelopes) then the population of impala would decrease in size.

So the answer is: an increase in the number of other grazing animals,

Answer:

B) an increase in the number of other grazing animals

Which type of genetic exchange occurs among bacteria in which dna is carried into a bacterial cell by means of a virus?

Answers

Answer:

Transduction

Explanation:

Among the three types of gene transfer in bacteria, transduction does not require physical contact between the two bacteria cell. Viruses that infect bacteria accidentally move pieces of chromosomal DNA from one bacterium to another. These viruses that infects bacteria are called bacteriophages.

Simply put, transduction is a process of genetic recombination in bacteria which involves the incorporation of the genes of a host cell (bacterium) into the genome of a viral cell (bacteriophage) and then conveyed to another host cell when the bacteriophage infects it. The process of transduction is of two types; generalized and specific depending on whether any gene or specific gene is transduced respectively.

The aim of these viruses when they infect bacteria cell is to harness the ability of bacteria to replicate, transcribe and translate their genetic material and use it to procreate into many virons or complete their viral particle.
