Answer:
The recombination frequency between two genes exhibits a positive correlation with the distance between them, that is, farther they are, and more will be the chance of recombination. Thus, recombination frequency is used to signify distance among the two genes, for example, 1 percent recombination frequency demonstrates distance of 1 map unit.
Let us consider that the heterozygous female of genotype AaBb can generate four kinds of gametes, that is, AB, Ab, aB and ab. Of these, the two gametes are the outcomes of recombination, or it can be said that 50 percent are recombinants. Thus, it can be concluded that in case of two linked genes, the maximum probable recombination frequency is 50 percent.
This shows that any genes, which are distant than 50 map units will function as unlinked and will function as if they were on distinct chromosomes, and the frequency of recombinant frequency will be 50 percent.
In the given question, it is given that the map distance between the two genes is 80 map units, that is, more than 50 map units. The maximum probable recombinant offspring will be 50 percent of the entire offspring.
Asexual reproduction is better because it is more convenient!
1. It only requires one organism
2. Results in more offspring
3. Usually a quicker process
OR
Sexual reproduction is better because it results in more genetic diversity!
1. Requires two organisms of the same species
2. Genetic material mixes together to create a random, unique combination
3. Recombination of genes decreases the chances of defects, diseases and mutations
Hope this helped some! :)
What is clear here is that sedation was provided by a physician or other qualified health care professional. Read at the CPT Coding Changes For Moderate Sedation in 2017. It states there will be several codes for moderate sedation. Your statement of the case is not complete, as age is important. The codes for moderate sedation is 99151 to 99157.
Answer:
carbon dioxide- burning of fossil fuels
fluorinated gases- industrial processes
methane- production and transport of oil and natural
gas
nitrous oxide- agricultural and industrial activities
Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
