If a test tube has been used, and its contents is supposed to be disposed, carefully pour the contents to the lavatory with a confirmation of a professional (as it may damage the pipelines of the sink) and ensure that there are no splashes created that can contact the human skin. Wash the test tube thoroughly and let dry.
The answer is a Reptile.
Because it lives in water (also out) and has rough skin.
Answer:
DNA plasmid that contains both "old" and "new" gene segments and confers new characteristics to the organism in which it is placed.
Explanation:
During the genetic engineering procedure, which aims at producing an organism with better and desirable characteristics, a DNA called PLASMID is usually used to convey the gene of interest into the organism.
A plasmid is a self-replicating extra-chromosomal DNA found in the bacterial genome. The plasmid becomes a RECOMBINANT PLASMID when a foreign DNA of interest is inserted into it, in order to act as a vector (carrier). Therefore, a recombinant plasmid is a DNA plasmid that contains both "old" i.e bacterial genome and "new" i.e foreign gene segments and confers new characteristics to the organism in which it is placed.
A zygote will not undergo meiosis
in an environmental state that is not favorable for the zygote’s survival i.e.
the chance of the zygote to survive is not certain. Take for example, chlamydomonas
will form a zygote under normal asexual mitotic reproduction in a favorable environmental
condition. However, under unfavorable environmental conditions the organism
also reproduce sexually to form a zygote but will never proceed to meiotic
division because of the unfavorable environmental state.
