Many scientists claim that the facts support the belief that climate change is really happening. By examining scientific researc

h and evidence, you will better understand issues and cut through the myths. As you read in the unit, it is important to carefully consider evidence because there is a lot of information in the public sphere that looks like science but it is not based on the scientific method. For this activity, you are going to do your own research on global warming and sort out the facts for yourself. Do research online to find evidence about global warming. To find reliable information, be sure that you use reliable websites, such as those from government organizations (.gov) or universities (.edu). You can also look at publications that are reputable, such as Popular Science, Discover, or National Geographic. Find a minimum of three sources that provide evidence about global warming.

\boxed{\color\red\huge\tt\bold\purple{Answer}}

The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view,[7] though a few organizations with members in extractive industries hold non-committal positions,[8] and some have attempted to convince the public that climate change is not happening, or if the climate is changing it is not because of human influence, attempting to sow doubt in the scientific consensus.

Assume that two genes are 80 map units apart on chromosome II of Drosophila and that a cross is made between a doubly heterozygo
STatiana [176]

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.

Which type of reproduction is better, sexual or asexual. Provide at least three reasons to support your answer.
yulyashka [42]
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.

Match the name of the greenhouse gas with one of the human activities that produces it.
Svet_ta [14]

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.
