The answer is the smoking of crack cocaine. This drug is more simply known as<span> '</span>crack'<span>, and is widely considered the most addictive form of cocaine. Crack is widely used as a recreational drug, and was first widely used in US cities during the mid 1980s. The term 'crack epidemic' describes the rapid increase in its use and the resulting socio-economic problems that resulted.</span>
Answer:
up and running the way I could
Explanation:
know I don't know how I wish
The control variable in any experiment is designed in order to apply the same steps of the experiment but with no change happens in the observations.
In this experiment, the student tries to know the effect of solubility of different water-soluble salts (NaCl, CaCl2 and KCO3) on the melting point of the solution. All these salts dissolve in water and give some effect on the melting point except for the sand as the sand doesn't dissolve in water.
Answer:
-if I'm not wrong the technique is used to produce the bacteria cell is DNA cloning because after a ligation, the next step is to transfer the DNA into bacteria in a process called transformation.
-The organic compounds scientist used to cut DNA is enzymes.
-the possible result would be the transformations made and selection of the bacteria.
Answer:
32 possible combination of chromosome
Explanation:
According to the law of independent assortment as proposed by Mendel, alleles of a gene will separate into gamete independently of the alleles of another gene. Since this organism contains 10 chromosomes in its somatic cell, it will undergo meiosis to produce half number of chromosomes in its gametes i.e. 5 chromosomes.
If we know the haploid number of chromosomes of an organism i.e. n, we can calculate the possible combination of chromosomes that will be present in its gametes as a result of independent assortment during meiosis using the formula:
2^n, where n= haploid no. of chromosome
If n is 5 chromosome in this case, the possible combination of chromosome in its gametes will be 2^5 = 32. Hence, as a result of independent assortment, an organism with 10 chromosome in its somatic cell will produce 32 possible combinations of chromosome in its gametes.
