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.

A. Humans were only related to
chimpanzees, but not other animals
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.

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.

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.

A commercial fish farm claims that each of its tanks used for growing fish is a “complete ecosystem that produces no biological waste.” Does this claim imply that the tanks contain which of the following?
A. decomposers
B. fish predators
C. at least four trophic levels
D. a diverse variety of species
Answer:
ff
Explanation:
ff
The claim that each of the fish farm tanks is a "complete ecosystem that produces no biological waste" does not imply that the tanks contain decomposers, fish predators, at least four trophic levels, or a diverse variety of species.
Why Decomposers are essential components?Decomposers are essential components of any ecosystem, as they break down dead organic matter and recycle nutrients back into the ecosystem.
The claim that the tanks produce no biological waste suggests that the waste products of the fish and other organisms are somehow being recycled within the tank, but it does not necessarily imply the presence of decomposers.
Fish predators are not necessary components of a fish farming system, as the purpose of the tanks is to raise fish rather than to provide a natural ecosystem.
Having at least four trophic levels and a diverse variety of species are both characteristics of a complex and diverse ecosystem, but they are not essential for a fish farming system to be successful.
Overall, the claim made by the fish farm is likely based on their use of technologies such as recirculating aquaculture systems, which aim to minimize or eliminate the waste produced by fish farming operations, rather than on the creation of a self-sustaining ecosystem.

In addition to all being autotrophs, what important feature do all three plants share?
A)
seeds
B)
flowers
C)
xylem and phloem
D)
seeds in ovaries
Answer:
C)
xylem and phloem
Explanation:
The three plants in the picture are all vascular plants. Vascular plants have dedicated tissues that aid the transportation of food and water. They have a root, shot, and the vascular system itself. The two main types of vascular tissues are the xylem and the phloem.
The xylem is used in the transportation and storage of the water-soluble nutrients. The phloem transports organic molecules such as the different types of sugars and proteins to the cells that require them in vascular plants.
