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:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
Answer:
Explanation: Eagles are endotherm and homoeothermic.
Coyote are endotherms and homoeothermic.
Walrus are Endothermic and homoeothermic.
The above organisms maintain constant internal body temperature irrespective of fluctuations in surrounding temperature.
Artic shrimp are ectotherms; and homoeothermic. Despite the fact that it has negligible source of intenal heat, its environmental temperature is relatively stable, therefore it is both ectotherms and homoeothermic.
Butterfly, freshwater catfish, Salamander are Poikilothermic. These organism’s body temperature fluctuates with the immediate surrounding temperature. They lack internal body temperature.
Temporary teeth
I -
3/3 C - 1/1 P - 4/4 M - 0/0 = 16 x 2 =
32
Permanent teeth
I -
3/3 C - 1/1 P - 4/4 M - 3/3 = 22 x 2 =
44
where I = incisors, C = canines, P =
premolars and M = molars
Dental formula can be defined as the number of teeth on one
side of the upper jaw over the number the same type of the number of teeth at the
lower jaw. Thus, the formula is for one side of the mouth and the total number
of teeth is the total in the formula multiply by 2.
