Answer:
The answer is option C : a bacterium
Answer: it is used primarily in conjunction with surgical anesthesia
Explanation: it is one of the synthetic opioid , it is used intravenously as anesthesia and to treat pain. It is given with a muscle relaxant and a sedative hypnotic. The effect is quick in the body and central nervous system and can last less than 2 hours.
Answer:
0%
Explanation:
This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.
A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:
TT- T and T
Tt- T and t
Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.
TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.
The correct answer is D.
The domain is the broadest category in the classification of living organisms. All the living organisms are placed in three domains, which are archaea, bacteria and eukaryotes. The prokaryotes are separated into two groups, that is archaea and bacterial based on the differences in their 16S rRNA genes. Amoeba is classified as an eukaryotes because, its cell is more developed than that of bacteria.
The type of inversion is Paracentric inversion.
There are two types of inversion at the chromosome level, depending on the centromere:
Paracentric inversions:
the centromere is not included in the inversion.
Pericentric inversions:
The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.
the structure that will form during synapsis is inversion loop.
These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.
