Which statement correctly describes the relationship between air temperature and air pressure?
1. Warm air rises, creating an area of low pressure.
2. Cool air sinks, creating an area of low pressure.
3. Warm air sinks, creating an area of low pressure
4. Cool air rises creating an area of low pressure.

Answers

Answer:

jayfeather friend me

Explanation:

Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.

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

Answers

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.

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic
isolation allow for the change of gene pools over time?

Answers

bio-geographic isolation affects the random changes that take place within gene pools
The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.
The mixing of there genes within the same species is separated by the geographical barrier.
The barrier allows the mating of the species in a different way as compared to the previous one.

Answers

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.

Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.

Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.

The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.

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.

Answers

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.
