Answer:
10°C.
Explanation:
Heat released in any system can be calculated as follows:
Heat released = m c DT
Here, m is the mass , c is the specific heat and DT is the change in temperature.
Heat released = 200 kcalories = 200,000 calories
The mass of water = 20 kg = 20000 g
The specific heat of water = 1 cal / g degree
The rise in the temperature is as follows:
heat released = m c DT
200,000 = 20,000 ( 1) (DT)
DT = 10°C.
Thus, the answer is 10°C.
Answer:
C) extended, with more than two conclusions
Explanation:
We can state that the argument shown in the above question is an extended argument because it consists of more than one subarguments, which are "Like 'The Simpsons' is a popular television show" and "It follows that it has many loyal fans whose viewing habits would be dangerously interrupted if the show were withdrawn ". Moreover, we can conclude that the argument has two conclusions which are:
Answer:
The development in the field of genetic engineering allowed the production of insulin in E. coli and yeast, which have been approved for therapeutic applications in human by FDA [14,15]. Nowadays, recombinant human insulin is mainly produced either in E. coli or Saccharomyces cerevisiae.
Answer: E.coli or Escherichia coli
Explanation:
1. Obtain the segment of DNA in a human chromosome that contains insulin gene. Cut the gene using a restriction enzyme. This enzyme cuts the restriction site at the two ends of the gene to produce sticky ends. Each sticky end is a single strand sequence of DNA bases. These bases can pair with complementary bases to form a double strand.
2.Obtain a plasmid from a bacterium. Cut the plasmid with same restriction enzyme. This produces 'sticky ends' complementary to the ends of the Insulin gene.
3. Mix the plasmid with the DNA segment containing the human insulin gene. The human insulin gene will bind to their sticky ends. Add the enzyme DNA ligase to seal the human plasmid containing DNA from two different organisms is recombinant plasmid
4. Mix the recombinant plasmid with E.coli bacterium. Apply temporary electric shock. This opens pores of cell surface membrane of the bacterium for the plasmid to enter.
5.The transgenic bacterium will use the new gene to make insulin
The insulin protein has to be extracted and purified before it can be used
B. Cell Membrane
C. Mitochondria
D. Ribosomes
E. Chloroplasts
F. Nucleus
G. Vacuole
H. Golgi apparatus
Answer:
R.H. Whittaker introduced the five kingdom classification of organisms .
The cascade of different hormones,that occur during adolescence is referred to as puberty.
Explanation:
Puberty is defined as a period of sexual maturity when Reproductive organ of the individual become functional. This results from several hormonal changes that take place in the body during this period.
In males, puberty is characterized by onset of spermatogenesis and in females, it is characterized by onset of ovulation or menstrual cycle.
During puberty, the individual develops secondary sex characters.
