Answer:

prostrates. is the answer to this question

Answer:

To answer this question, we must define the two key terms within this question, organism, and ecosystem.

Organism, by definition, is "one animal, plant, or single-cell".

Ecosystem, by definition, is a "community of organisms interacting with their environment".

For an organism to survive in a certain ecosystem, the ecosystem must provide a certain amount of basics:

1) Food: The ecosystem must provide edible substance to the organism, whether as plants, other animals, or a way to get nutrients.

2) Water: Of course, there are plants and animals that can survive long time without water. However, water is a key component to the survivability of the organism.

3) Shelter: Most animals must have a long-term shelter against the weather. Shelter also provides protection against predators.

4) A way to reproduce: Whether an animal reproduces asexually or sexually, the organism must have a way to keep the population alive. Remember that the disappearance of an organism can greatly affect the food chain & web, and can lead to the destruction of the ecosystem.

Organisms in an ecosystem survive by transforming energy through photosynthesis or consumption, maintaining balance by competing for resources, avoiding predators, reproducing, and not degrading their environment.

Organisms in an ecosystem survive by maintaining a balance through the flow of energy and the cycling of nutrients. The energy needed by ecosystems primarily comes from sunlight. Plants conduct photosynthesis using sunlight to produce food, while animals consume plants or other animals to gain energy.

In addition to obtaining energy, organisms must maintain a stable internal environment, compete for limited resources, and reproduce successfully. Ecosystem stability requires a healthy balance among various species populations, each having different reproductive strategies and competing in their physical and geographic environment.

Consider a pond ecosystem as an example: it includes birds, fish, frogs, insects, plankton, and aquatic plants. These organisms compete for resources such as light and nutrients, avoid predators, and strive to reproduce, ensuring their survival without degrading their habitat.

Answer:

The answer is B

(also, this is chemistry not biology)

An ion is an atom or molecule that gains a positive or negative charge by losing or gaining electrons, resulting in an unequal number of protons and electrons. Cations are positive ions, while anions are negative ions.

An ion is defined as an atom or molecule that has acquired a positive or negative charge due to the loss or gain of one or more electrons, resulting in an unequal number of protons and electrons. These charged entities play crucial roles in various chemical reactions and form the essential basis of many phenomena in physics and biology. When an atom loses electrons, it becomes a positively charged cation, and when it gains electrons, it becomes a negatively charged anion. The electric charge of one electron is equal to the charge of one proton, but with an opposite sign.

Answer:

Study 1:

Independent- Light

Dependent - flowering patterns

Study 2:

Independent- Penicillin

Dependent - Growth of E. Coli

Study 3:

Independent- Progesterone

Dependent - Ovulation

Explanation:

To differentiate independent and dependent variables, just remember that the dependent variable is not changed by the researcher. It changes depending on the independent variable. in short, it is what is being tested on. The independent variable on the other hand, is manipulated by the researcher to elicit a change in the dependent variable.

In the three study scenarios provided, the independent variables 'light', 'penicillin', and 'progesterone' are manipulated to observe the outcomes on the dependent variables 'flowering patterns', 'growth of E. coli', and 'ovulation', respectively.

Understanding the concepts of independent and dependent variables is crucial for analyzing experimental studies. In each given study, the independent variable is the one that is being manipulated or changed by the researchers, while the dependent variable is the one that is being measured or observed to see how it is affected by the changes in the independent variable.

Study Identifications:

Study 1: The independent variable is light, because it's what the researchers alter to observe the effect. The dependent variable is flowering patterns of plants because it's what changes as a result of light exposure.

Study 2: The independent variable is penicillin, and the dependent variable is the growth of E. coli, which is measured to determine the effect of penicillin.

Study 3: The independent variable is progesterone, as this is what's being tested, and the dependent variable is ovulation in rats, as this is what is influenced by the hormone.

When constructing data tables or charts, remember to place the independent variable on the x-axis and the dependent variable on the y-axis. Also, ensure rows and columns are clearly labeled with appropriate units.

Answer: C. imprints of organisms known to have lived during a specific time period.

Explanation:

Index fossils are the fossils which are used to compare the age of the other fossils. These fossils can be used for relative comparison and providing the relative age of the fossils. These fossils can be considered to be living in a particular geological time. These fossils exhibit a wide geographical distribution but exhibit a short time duration or specific time of their survival.

These fossils can be used for determining the geological time scale of the organisms or rocks as these allows the correlation of the entities with the strata.

These fossils can be found as imprint fossils over the surface of the rocks as the organisms after death buried inside the heap of earth. Their soft body parts are consumed by the microbes and the hard remains are left. These hard remains leave their impression over the hard surfaces such as rocks.

On the basis of the above description, C. imprints of organisms known to have lived during a specific time period. is the correct option.

The fossil record of horses shows that over millions of years, horses have become larger, developed hooves in place of toes, and have adapted to eat grass instead of leaves.

The fossil record of horses was found in sedimentary strata since the beginning of tertiary period in a life span known as Eocene. That is about 50 million years ago.

According to evolution theory, it is very possible to follow horse evolution through millions of years: how the horse became larger and stronger, lost most of its toes, and how the structure of its tooth changed when its moved from eating plant, trees and shrubs to feeding on high dry grass. The horse evolution is believed to been fueled by drying and cooling climate.  

The first set of horses lived in humid forest; it is a forest that is full of plant rich in foliage. Their toes, with three at the rear and four at the front spread out at different angle, and this really helped them from drowning into marshy grounds. Plants rich in foliage disappears as climate became drier and new huge grass fields formed. As a result of dried land, the grazers become better runner and were able to escape predators.  

All the horses are categorized as the same family (Equidae) because they all resemble each other and due to the striking similarities, it can be hard to recognize any differences through the study of fossils skeleton alone.

Resilient

Explanation:

In ecology, resilience (or resilience stability) is the ability of a system to restore its balance after it has been disrupted by a disturbance, that is, its resilience. It differs from resistance, which is the ability of a system to maintain its structure and function after a disturbance. The term resistance (or resistance stability) is the ability of a system to maintain its structure and function in the face of a disturbance. For this reason, we can say that resilience best describes how Alaska's spruce forest reacts to fire.

Explanation:

Its molecules move very faster and some atoms go through ionization because the collision of the atoms because their increase in movement speed and intensity. Ionization is the loss or gain of electrons, which are around the nucleus of atoms. Since equals charges repeal and electrons have negative charges, they move from their levels of energy during collisions. Its conductivity can also become lower, because the flow of electrons can be interrupted by the violent movement of the molecules.

- Keystone herbivore

- Predator

Explanation:

The prairie dog is a herbivore, as it feeds upon plants and their products. But that is not its only role. The prairie dog also helps in the aeration of the soil, which is excellent for the grasses. It fertilizes the soil, and it spreads out the seeds, which contributes to much denser and healthier vegetation in the prairie. It is also a prey, namely of the coyote. So all in all, the prairie dog is a keystone herbivore, as it is a species on which the ecosystem heavily relies on. The coyote's role in the ecosystem is much simpler, it is a predator, thus it has a role of regulating the population of the herbivores, such as the prairie dog.

The terms that best describe the role played by each organism in an ecosystem is D. The prairie dog is best described as a keystone herbivore , and the coyote is best described as a predator.

The cell membrane is said to be fluid. D. it moves sideways

At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic in which transmembrane proteins can move laterally in the lipid bilayer.

According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.

Cell membrane is fluid because individual phospholipid molecules and proteins can diffuse within their monolayer and thus move around. The fluidity is affected by: The length of the fatty acid chain. Here, the shorter the chain the more fluid is the membrane.

2. When a mineral is nutritionally inorganic, it means that it is without any organic (carbon-based) molecule. When a mineral is nutritionally organic, it means that it is chelated or bound to organic molecules, such as an amino acid.

3. Oxides are distinguished from other oxygen-bearing compounds such as the silicates, borates, and carbonates, which have a readily definable group containing oxygen atoms covalently bonded to an atom of another element.

4. any compound of sulfur and a metal or other electropositive element or group while sulfate is (organic chemistry) any ester of sulfuric acid.

5.Native element. Even a single native element can occur in widely diverse environments. Native iron ( kamacite ), for example, is found primarily in meteorites. The iron meteorites called hexahedrites are almost completely composed of kamacite, and in those called octahedrites it is the principal constituent.

Answer:

1.For minerals to form through natural processes, the correct elements must be present in the right amounts. The physical and chemical conditions, such as temperature, pressure, and pH, must be favorable. In addition, there must be enough time for the atoms to become ordered. Otherwise the mineral grains will remain very small.

2.In most cases, minerals are considered inorganic substances because they’re not derived from or made by living matter, such as plants and animals. There are a few minerals, however, that are produced by living organisms.

3.In oxides, the oxygen atoms bond directly to one or more metals. In other minerals, such as carbonates, sulfates, and silicates, the oxygen atoms are part of molecules in which the oxygen is already bonded to another element, such as carbon, sulfur, or silicon. These molecules then bond to other elements.

4.In sulfides, sulfur atoms bond with one or more metals. In sulfates, the sulfur atoms are part of a molecule that also contains oxygen. The sulfate molecule is what bonds to other elements.

5.Native elements are unique in that they’re composed of atoms of a single element. For example, gold is composed only of gold atoms. Silver is composed only of silver atoms.
