Controlling populations of harmful invasive species is a challenge. Using any pest control method could potentially harm the ecosystem. If you had to decide whether to use the frog control method proposed by the scientists in the video, what five questions would you ask the scientists before making your decision?

By taking the quotients between the percentages, we will get:

1) 0.7702)0.2703) 0.0124) 0.5225) 0.478

How to get the probabilities?

1) The probability of not getting an orange one is equal to the quotient between the percentage of not orange ones, and 100%.

We know that 23% are orange, then 100% - 23% = 77% are not orange, so the probability is:

P = 77%/100% = 0.770

2) 12% are red, 15% are green, so 27% are either red or green, the probability is:

P = 27%/100% = 0.270

3) To get 3 blues we can estimate the probability as:

P = (23%/100%)^3 = 0.23^3 = 0.012

But this would be incorrect, as we draw blue peanuts, the probability of drawing another is reduced (because now there are less on the package).

4) Same procedure as before, 15% are green, so 85% are not green, so to draw 4 non-green ones the probability is:

P = (85%/100%)^4 = 0.522

5) The probability of getting at least one green in 4 daws is 1 less what we got above.

P = 1 - 0.522 = 0.478

Explanation:

Generativity versus stagnation is the seventh of eight stages of Erik Erikson’s theory of psychosocial development. This stage takes place during middle adulthood between the ages of approximately 40 and 65. The eighth and last stage is integrity vs. despair.

During this time, adults strive to create or nurture things that will outlast them; often by parenting children or contributing to positive changes that benefit other people. Contributing to society and doing things to benefit future generations are important needs at the generativity versus stagnation stage of development.

What Are Generativity and Stagnation?
Generativity refers to "making your mark" on the world by caring for others as well as creating and accomplishing things that make the world a better place. Key characteristics of generativity include:

Making commitments to other people
Developing relationships with family
Mentoring others
Contributing to the next generation.

As you might imagine, these sorts of things are frequently realized through having and raising children. Those who are successful during this phase will feel that they are contributing to the world by being active in their home and community.

Stagnation refers to the failure to find a way to contribute. These individuals may feel disconnected or uninvolved with their community and with society as a whole. Some characteristics of stagnation include:

Being self-centered
Failing to get involved with others
Not taking an interest in productivity
No efforts to improve the self
Placing one's concerns over above all else
Those who fail to attain this skill will feel unproductive and uninvolved in the world.

Answer and Explanation:

1. The experimental units are the 80 people used in the experiment. This is because an experimental unit is the smallest element of an experiment where the treatment is applied. In this case, the smallest element of the experiment subjected to the experimental treatments is the people who are participating.

2. Two treatments are used in this experiment. Experimental treatment is what you want to measure and test through the experiment. In this case, the experiment wants to test the difference between ordinary Nike shoes and Nike shoes manufactured to reduce arthritis cases, that is, there are two shoes tested, therefore, there are two treatments.

3. A potential problem presented in the project is the lack of homogeneity of the experimental units. This is because, although all the people who are participating in the experiment show first signs of knee arthritis, the researcher did not define the age, gender, height and weight that the volunteers should have to participate in the experiment. This can promote inaccurate data as these elements are also important in the onset of arthritis. To improve this problem, the researcher should have selected people of the same age, height, weight and gender.

4. A placebo-controlled, double-blind study is a study that seeks to discover the effects of an element on a person's body. In the case shown above, the element is Nike shoes that slow the progression of knee arthritis. In the case of the placebo-controlled, double-blind study, the individuals who will test the studied element will be divided into two groups. One of the groups will receive the element capable of causing changes in the body (in this case Nike shoes that delay arthritis), while the other group will receive a placebo, which is an element exactly the same as the element that promotes modifications, but has no function. . This type of study is called double-blind, because neither the researcher nor the volunteers know which group they are in. In this way, the experiment is able to present real results data, because neither the participants will be psychologically led to think that they are feeling the modifications of the tested element, nor will the researcher be led to believe that these changes actually occurred.

5. The blocking can divide 20 men and 20 women for each group. This is because the experimental block limits the randomness in the formation of experimental groups when this randomization is very difficult to achieve. Thus, when using the blocking , the researcher configures the randomness of the groups, which will facilitate the analysis of results and prevent all women from forming a group and all men from forming another group, as well as preventing groups from being formed with different amounts between men and women.

my friend who does edge said no, but they have this smart technology to know if you are cheating .. when you start an exam you have to type a paragraph so they can see how you type and if in the exam it is different it will assume you are cheating. you must have your camera on cause it tracks how your eyes move .. and it also knows if you switched out of the test tab or not.

Answer:

Numerous studies have shown that caffeine is toxic to a variety of wildlife at high concentrations. The effects are less clear in cases of continual exposure at low levels  like those documented in nature by Granek and Nagoda  because little research has been done in this area. Studies involving the use of caffeine on plants have shown that, initially, cell growth rates are stable but soon the caffeine begins to kill or distort these cells, resulting in a dead or stunted plant.
