Answer: D. The genes for antibiotic resistance help the transformed bacteria survive in their environment.
Explanation:
First and foremost, we should note that plasmids used in the delivery of DNA typically consists of genes which helps in antibiotic resistance.
Based on the question given, we should note that the genes for antibiotic resistance help the transformed bacteria survive in their environment. This is because cells that have been treated with plasmid are able to survive and grow compared to those that have not been treated with plasmid which are eventually killed by the antibiotic.
Answer:
equivalent resistance = R1R2/R1+R2
= 30/13 ohm
V = IR
= 5×30/13
V = 150/13 ohm
Answer:
because the ecosystems are not adopted to this type of animals thus the invasive species will have the upper hand and will spread to the native animals disadvantage

Plant development is seeded in the perspective that a cell divides itself to form a tissue and tissues grouped will become an organ and the organism itself. The cell hierarchial model is followed in the development in both of these diverse however seemingly similar organisms. </span>
The correct answer is B. Two oppositely-charged ions
Explanation:
In chemistry, ionic bonds only occur between ions oppositely charged, this means one of the ions has to be positively charged and the other has to be negatively charged. This is because there is a natural attraction between particles with different charges and this leads to the formation of chemical bonds. Also, this bond implies the transfer of electrons between ions. In this context, this type of bond can only occur with oppositely-charged ions. Moreover, particles with the same charges either negative, positive, or neutral do not experience attraction and cannot form ionic bonds.
