Darina [25.2K]

Answer:

The answer is 97%.

Explanation:

The zika virus' 1% incidence rate in the population has no effect over the probability of the patient being infected or not. If the test has a 3% false positive rate that means that if it is positive, the results have a 97% chance of being true. Therefore the chance that the person who took the test and had a positive result being actually infected is 97%.

I hope this answer helps.

Eduardwww [97]

DNA plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major role in the everyday workings of your cells. It does this by creating molecules, such as enzymes, that regulate cell functions. These enzymes belong to a larger class of molecules known as Proteins.

  • DNA is important in terms of heredity. It packs in all the genetic information and passes it on to the next generation. The basis for this lies in the fact that DNA makes genes and genes make chromosomes. Humans have 23 pairs of chromosomes – a total of 46 chromosomes.
  • Information that is stored in DNA molecules is used to manufacture proteins through the process of transcription and translation.
  • During transcription, DNA molecules are used to generate mRNA (messenger RNA), which then undergoes translation in the cytoplasm to generate proteins. These proteins include enzymes that control or regulate and catalyze different biological reactions in the body.
  • Additionally, one of the characteristic of protein is being protein in nature which means like proteins they are produced through translation in the ribosomes.

Name 3 reasons why recycling is bad
morpeh [17]
1. Air pollution would still be an issue since fossil fuel trucks that produce exhaust have to go pick up recyclable items and bring them back. Also, the recycling process itself produces a lot of pollutants from inside the factory. 

2. Contamination is also a huge obstacle in the recycling industry. Sometimes there are errors with sorting through recyclable stuff and let's say, for example, a spray can gets mixed in with other types of recyclables; it can contaminate the new products.

3. Most plastics can not be recycled. There are about seven types of plastic that we find and encounter on a day to day life, but only two of those plastics are recyclable. What isn't recyclable will be collected, processed, sorted and then thrown into a landfill. 

Hope this helps.

Ipatiy [6.2K]
The overload principle is defined as working harder as the body essentially grows fitter. This is to stimulate muscle hypertrophy against resistance as well as overall cardiovascular health. For instance, an experienced body builder should lift more weight up up to failure to grow even fitter.
