<h3>Global travel and spread of certain species</h3>

Explanation:

Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.

When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.

The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.

Calix’s karyotype showed that he has a genotype of XXY. Explain how nondisjunction caused Calix to be XXY.
Juli2301 [7.4K]

Answer:

A XY or XY gamete fuses with a normal gamete (X or Y)

Explanation:

Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.

The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.

Anna [14]

The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment.  Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.

While the introduction of the mutant synthetase gene restored some of the growth characteristics, this strain still does not gro
katen-ka-za [31]

Answer:

A and D

Explanation:

Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.

If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:

  • Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
  • The normal synthetase might be present but not in an adequate amount.
