The beetles on the previous page are all different species. How can change over time account for the diversity of beetles
Answer:
Mating and evolution
Explanation:
The beetles evolve as guided by the natural selection process of evolution. Natural selection leads to the evolution of traits that are best for an offspring to survive successfully under environmental stress.
These stresses in due course of time leads to evolution of further favorable traits in beetles.
With new traits originating in a given population of beetle, the population evolve.

Explain two ways the geography of China had a negative impact on the people.
Answer:
Explanation:
Air pollution. According to the Environmental Protection Agency's air quality scale, any pollution rating above 300 means the air is unsafe to breathe. Under these conditions, people should stay indoors with an air purifier running and remain as motionless as possible, according to U.S. Embassy Beijing guidelines.
Water pollution. Thousands of dead pigs floating past Shanghai, dramatic though they are, may be the least of China's water pollution worries. In January, a chemical accident leaked benzene, a known cancer-causing agent, into a tributary of the Huangpu River (where the dead pigs were discovered).
Desertification. China has a history of intensive agriculture going back millennia, so it's perhaps unsurprising that much of the nation's 3.7 million square-mile (9.6 million square kilometers) territory has been subject to deforestation.
Biodiversity. Closely related to deforestation and desertification is the issue of habitat loss and the resulting drop in biodiversity. As vast areas of forest are cleared for farmland, bamboo plantations, timber and fuel wood, endangered animals like pandas struggle to survive.

Select one of the Case Studies and imagine you could interview the forensic scientist who studied the blood evidence. Write the questions and answers from the interview. Be sure your questions demonstrate what you have learned about blood and blood-spatter evidence.
Answer and Explanation:
1. Why can blood sentence a criminal? The blood contains genetic material from both the victim and the criminal who can often get hurt during the crime and drop particles of blood, skin, hair or other elements that will allow him to be recognized and sentenced.
2. In addition to the genetic matrix, what can blood particles present? The blood particles show the type of weapon used in the crime, the number of blows, whether the victim died immediately or not, the position between the victim and the aggressor and the time the crime was committed.
3. Is there a period of time when blood can no longer be used as evidence of a crime? The more time the blood spends in contact with the more deteriorated environment it gets and thus, all the evidence it contains becomes more difficult to analyze, however, with the use of tests and correct equipment, we are able to analyze blood particles that they were exposed for a long time.
4. What are the most used tests? We generally use origination tests, which work on the basis of Hemoglobin. However, it is rare that only one test is used, and we can use luminescence tests, tests of certainty and human origin, among others.
PLEASE HELP ASAP!!!!! Dr. Nicole and her team are tasked with creating a new AP Psychology test. To do this, she must take several concepts into consideration. Define each term below, and explain how it will play a role in Dr. Nicole’s project.
Operational definition
Standardization
Normal curve
Reliability
Validity
Bias
Answer:
Operational definition
It is a definition of a variable in terms of precisely how it is to be measured. These measures generally fall into one of three broad categories: self-report measures, behavioral measures, and physiological measures. Generally, operational definitions should be concrete and measurable. Defining variables in this way will allow Dr. Nicole and her team to see if the AP Psychology test they are developing has validity. Also, they need operational definitions so as to understand how generalizable the findings of their test are.
Standardization
It refers to the consistency, objectivity, and uniformity of how tests are administered and scored. Many psychological tests are about comparing an individual's score to other people's scores to see how that person did in a specific measure. It is important for Dr. Nicole and her team to understand the concept of standardization so that the results of the AP Psychology test they're developing can be empirically documented, and the test scores can be shown to have a relative degree of validity and reliability prior to data analysis, such that the results of the AP Psychology test is generalizable and replicable.
Normal curve
The normal curve is a hypothetical distribution of scores that is widely used in psychological testing. Normal curve distributions are very important in psychological testing and assessment because of the relationship between the mean, standard deviation, and percentiles, and is used to characterize complex constructs containing continuous random variables. It is important for Dr. Nicole and her team to know whether scores are normally distributed because it makes a difference in the kind of statistical tests that are appropriate for analyzing and interpreting the numbers. When measurements produce a normal distribution, certain things are predictable. In fact, many behavioral measurements result in normal distributions.
Reliability, validity, and bias
Reliability is when a test or assessment consistently delivers the same results. Dr. Nicole and her team can strengthen the reliability of their test by providing data collectors and respondents with clear instructions on how to administer and complete the test.
Validity is when a test accurately measures what it intends to measure. Dr. Nicole and her team will know if their measurement is valid when it produces results addressing the specific outcome they wish to measure using the AP Psychology test. Validity is also supported when the results produced by the AP Psychology test can be corroborated by information from other sources.
Finally, tests should be free of bias, which is when different groups of people consistently have different scores on an assessment. Results are considered biased when they are systematically skewed or distorted, which is due to several reasons such as the over- or under-representation of particular groups in the dataset, and due to question wording that tends to encourage or discourage particular responses. The timing of data collection can also systematically bias results. These are the things that should be avoided by Dr. Nicole and her team.

PLEASE HELP! LMK N THE COMMENTS WHAT U WANT FOR ANSWERING AND I WILL GIVE Which of the contributions above do you think was the most helpful and made the largest difference for the country in its fight in World War I? Explain your answer.
Answer:
Convinced that Austria-Hungary was readying for war, the Serbian government ordered the Serbian army to mobilize and appealed to Russia for assistance. On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe’s great powers quickly collapsed.
Within a week, Russia, Belgium, France, Great Britain and Serbia had lined up against Austria-Hungary and Germany, and World War I had begun.
World War I brought about massive social upheaval, as millions of women entered the workforce to replace men who went to war and those who never came back. The first global war also helped to spread one of the world’s deadliest global pandemics, the Spanish flu epidemic of 1918, which killed an estimated 20 to 50 million people.
World War I has also been referred to as “the first modern war.” Many of the technologies now associated with military conflict—machine guns, tanks, aerial combat and radio communications—were introduced on a massive scale during World War I.
The severe effects that chemical weapons such as mustard gas and phosgene had on soldiers and civilians during World War I galvanized public and military attitudes against their continued use. The Geneva Convention agreements, signed in 1925, restricted the use of chemical and biological agents in warfare and remains in effect today.
