What causes gene flow ?
Answer: Evolution and Migration
Explanation: When evolution occurs genes can be passed on through natural selection. The gene flows occur when there is migration because they can be transferred from different types of populations.

Accoring to the data table, Molly observed rust on the sample of iron filing and dries the sample thoroughly. She then finds the mass of the entire sample and finds it has more mass than the 188g of the original sample. As the rusted iron filing occurred in an open system, which of the following best explains the increase in mass?
Select one:
A. The sample gained mass because rust is a different color than the iron fillings, and the different color rust has more mass that the original iron fillings.
B. The sample gained mass because the iron fillings combined with oxygen in a chemical reaction, thus making the final rusted sample to have more mass.
C. Molly made a procedure mistake when measuring the mass of the entire sample. She should remeausre her sample.
D. The sample gained mass because rust is a physical change and the color change causes the mass to be more than the original sample.

Selective breeding programs, such as those that produce throughbreds, and captive breeding programs, such as those used to increase the takhi population, have different outcomes. Which statement both describes an outcome of one type of breeding program and is supported by the information about the takhi?
Select one:
A. Long-term slective breeding for specialized traits produces high-quality genes that improve a species’s changes of continued survival.
B. The takhi captive breeding program has demonstrated that populations with genetic diversity have a greater likelihood that some individuals will have traits that favor survival.
C. The takhi captive breeding program has proven that only a few individuals are necessary to produce a population with traits that ensure survival.
D. Long-term selective breeding for specialized traits can make it less likely that individuals will express desired traits.
Several tests have been evaluated in horses for quantifying insulin dysregulation to support a diagnosis of equine metabolic syndrome. Comparing the performance of these tests in the same horses will provide clarification of their accuracy in the diagnosis of equine insulin dysregulation. The aim of this study was to evaluate the agreement between basal serum insulin concentrations (BIC), the oral sugar test (OST), the combined glucose-insulin test (CGIT), and the frequently sampled insulin-modified intravenous glucose tolerance test (FSIGTT). Twelve healthy, light-breed horses. Randomized, prospective study. Each of the above tests was performed on 12 horses. Minimal model analysis of the FSIGTT was considered the reference standard and classified 7 horses as insulin resistant (IR) and 5 as insulin sensitive (IS). In contrast, BIC and OST assessment using conventional cut-off values classified all horses as IS. Kappa coefficients, measuring agreement among BIC, OST, CGIT, and FSIGTT were poor to fair. Sensitivity of the CGIT (positive phase duration of the glucose curve >45 minutes) was 85.7% and specificity was 40%, whereas CGIT ([insulin]45 >100 μIU/mL) sensitivity and specificity were 28.5% and 100%, respectively. Area under the glucose curve (AUCg0-120 ) was significantly correlated among the OST, CGIT, and FSIGTT, but Bland-Altman method and Lin's concordance coefficient showed a lack of agreement. Current criteria for diagnosis of insulin resistance using BIC and the OST are highly specific but lack sensitivity. The CGIT displayed better sensitivity and specificity, but modifications may be necessary to improve agreement with minimal model analysis. Copyright © 2016 The Authors.

Explain how our body systems work together to get oxygen into and around our body
PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

B. The first species appeared on Earth
about six million years ago
C. Each species was unchanged since the
moment of its creation.
D. All of the above
Answer:C each species was unchanged since the moment of its creation
Explanation:
people believed we were all the same and we just were there on the earth
Before Darwin's theory of evolution people believed that : ( C ) Each species was unchanged since the moment of its creation
Before Darwin proposed the theory of evolution most people believed that the species of plants and animals on earth were not connected to each other and could not have evolved from each other. because they believed that human species were outside the earth given that the earth was perceived as been too young.
Darwin's theory of evolution proposes that species evolve ( change in physical attributes ) over time through the process of natural selection. Darwin believed that man evolved from Apes over million of years.
Hence we can conclude that Before Darwin's theory of evolution people believed that : Each species was unchanged since the moment of its creation.

Explanation:
They often use up resources that other organisms need.
The reason of nonnative species a threat to biodiversity is because of using resources that other organisms need.
Reason why nonnative species a threat to biodiversity:It leads to various kinds of diseases. It acted like predators or parasites. It acted like a competitor or rivalry.

You have discovered a new organism. It only has one cell and was found in the ocean floor, at a vent of boiling hot water. The organism has a cell wall but no nucleus. Explain how you would classify this organism.
Answer:
The organism would be classified as a prokaryote. The reason for this, is because it's a simple organism that lacks a nucleus, and is unicellular. (hope that helps)
You would have to classify this organism in the category of a prokaryote. This is because a prokaryote has a cell wall that is made up of peptidoglycan while they lack a well-defined nucleus.
What is an Organism?An organism may be defined as a type of living thing that is typically made up of one or more cells depending on its structural identity and function.
Prokaryotes are simple types of organisms that lack complex genome organization. Such types of organisms have a cell wall, flagella, etc. but do not have a well-defined nucleus and other membrane-bound cell organelles.
Prokaryotic organisms have the tendency to survive on the ocean floor where the temperature of the surrounding water is of utmost high.
Therefore, you would have to classify this organism in the category of a prokaryote. This is because a prokaryote has a cell wall that is made up of peptidoglycan while they lack a well-defined nucleus.
