What is the independent variable shown on this graph?

O Only temperature ("C) is the independent variable.
Both flow time (s) and temperature ("C) are
independent variables.

What Is The Independent Variable Shown On This Graph?O Only Flow Time (s) Is The Independent Variable.O

Answers

Answer 1

The independent variable shown on this graph is option(b)i.e, Only temperature ("C).

Typically, the horizontal axis is used to indicate the independent variable. Temperature (°C) is labeled on the graph's horizontal axis, making it the independent variable. The vertical axis displays the dependent variable. It is Flow time in the graph (s). The dependent variable is determined by or explained by the independent variable, which is the input of the function or relation.

So you can see from the graph that the flow time, which is measured in seconds, depends on or is determined by the temperature, which is measured in degrees Celsius. The slope of the trend line is a measurement of the average change in the dependent variable for each unit change in the independent variable. The slope of the graph is calculated by dividing the temperature change by the flow time variation.

An independent variable's significance is a measurement of how much the network's model-predicted value varies for various values of the independent variable. Simply dividing the importance values by the largest significance values and expressing the result as a percentage is normalized importance.

Explanation:

There is nothing called as animal pollution... Types of pollution are air water and land

There is nothing called as animal pollution. Types of pollution are air water and land.

What is Pollution?

The introduction of hazardous elements into the environment is pollution. Pollutants are the name for these dangerous substances. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside.

For instance, the Antarctic ice sheet has been shown to contain chemicals and pesticides. The Great Pacific Garbage Patch is a massive accumulation of tiny plastic debris in the center of the northern Pacific Ocean.

Pollution is carried by air and water currents. Marine contaminants are dispersed widely by ocean currents and migrating fish. Radioactive material that has been unintentionally released from a nuclear reactor can be picked up by winds and dispersed globally.

Suppose a developer proposes to clear-cut a forest that serves as a corridor between two parks. To compensate, the developer also proposes to add the same area of forest to one of the parks. As a professional ecologist, how might you argue for retaining the corridor?

Answers

To compensate, the developer also proposes to add the same area of forest to one of the parks. As a professional ecologist

A habitat connecting wildlife populations in forest that are divided by human activities or constructions is known as a wildlife corridor, habitat corridor, or green corridor (such as roads, development, or logging). As a result, the detrimental effects of inbreeding and decreased genetic diversity (via genetic drift), which frequently occur within isolated populations, may be avoided. Additionally, corridors might make it easier for populations to repopulate after being diminished or exterminated by chance occurrences (such as fires or disease). so its important to save forest

If a hormone pathway produces a transient response to a stimulus, how would shortening the stimulus duration affect the need for negative feedback?

Answers

If a hormone system produces a brief response to a stimulus, shortening the stimulus length will have less of an impact on negative feedback.

Environment changes that can be noticed are known as stimuli. Sensitivity is the capacity of an organism or organ to react to outside stimuli.

When a stimulus is delivered to a sensory receptor via a stimulus transaction, a response is often generated.

A transitory reaction is how a system responds to a brief circumstance. There is a brief emergence of a temporary state. The duration of the inductance and capacitance's charge or discharge is what causes the transient condition.

The output is constant once they are fully configured. The steady-state condition is what we are referring to here.

Feedback is the result of stimulation or activity. Negative feedback is when a piece of a system's output reacts to its input in a way that modifies the outcome. To stabilize or restore internal equilibrium, the approach lowers a system's output.

When the stimulus strength is strong, accuracy and response time are quick; when the stimulus intensity is low, accuracy and response time are slow. The stimulus strength has a substantial impact on efficacy.

Answers

There are several things you can do to boost the species' carrying capacity, such as improving its food supply, shielding it from predators, and providing more nesting or reproduction places.

What would increase the carrying capacity of an ecosystem?

The quantity of decomposers has an effect on carrying capacity as well. Decomposers are creatures that break down and recycle dead organisms and organic debris. They keep dead stuff from piling up and taking up space in an environment. A species' population will grow in an ecosystem until it reaches carrying capacity.

What controls the carrying capacity for a species in an environment?

Carrying capacity is defined as the average population size of a species in a given habitat. Environmental considerations such as appropriate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.

Why is carrying capacity important to ecologists?

When scientists were trying to determine the molecule that can transform non-virulent bacteria into virulent bacteria, they found that a cell extract treated with rnase could still transform the cells. Why was this?.

Answers

Answer:

This question seems to be a little confusing but we can say.

Explanation:

Only the RNase-treated extracts using heat-killed cells are incapable of turning nonvirulent bacteria towards virulent ones.

Scientists conducted an experiment to discover Griffith's "transforming principle," which describes how transformation is indeed a method of recombining, transmitting, or even transferring genetic information across organisms either from one species to the next. They did this by using heat-inactivated cells & purifying their transforming factor.

As in experiments conducted by the scientists, the pure cells did not provide favorable outcomes, but they did show transformants that were quite close to DNA.  A scientist Avery, meanwhile, had his doubts that the outcome must be revised because the molecule did not contain DNA. This happens due to the transforming principle being unaffected by RNA degrading enzymes, whereas the only one cell extracts that can prevent the transformation of non-virulent bacteria onto virulent bacteria are those that have been treated with RNase.

After a heavy rain, earthworms come to the surface. How would you explain this behavior in terms of an earthworm's requirements for gas exchange?

Answers

Earthworms need to keep their skin moist for gas exchange but also require air beyond the sticky layer, which is why they come to the surface after a big rain.

The phylum Annelida, which includes terrestrial invertebrates, includes earthworms. While some Annelid species use specialized gills or paired projections called parapodia, many Annelid species breathe through their moist skin. They maintain life by exchanging gas through their skin. Areas of the bodily cavity where this takes place termed the capillary beds.The passive diffusion of gases over a surface is known as gas exchange. Gas exchange takes place when oxygen molecules enter the bloodstream and carbon dioxide molecules are expelled into the atmosphere.Reducing water loss and preserving a moist gas exchange surface are made possible by gas exchange (the lungs).
