The concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many
Elodia [21]

The concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many scientists but is not yet considered a law. Evolution by way of natural selection is most likely which type of concept?

a hypothesis that can be accepted as true based on repeated experimentation with similar results

a likelihood based on the chance that a particular event will or will not occur

a statement of fact that is generally accepted to be true and universal because it has always been observed to be true

a probability that is an answer to a scientific question and is based on prior knowledge or research

A hypothesis can be a true based which is found on repeated experimentation which has similar results. Thus, option "A" is correct.

<h3>What is evolution?</h3>

Evolution is termed as the change in characteristics which are heritable of population over successive generation.

A good example of biological organisation include molecules, individual organisms and level of species.

The repetition of formation of new speciation, they change within anagenesis and loss of extinction to all through the history of evolution in life.

The hypothesis explains more about a phenomenon. For a hypothesis to be scientific it needs to be tested first.

Thus, option "A" is correct.

In a quadrat that is 0.5m along each side, you count 3 daisy
Snowcat [4.5K]

Answer:

Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!

A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.

This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.

On his trip to the laguna atascosa wildlife refuge, mr Ortiz wants to analyze the overall health of alligator pond. Which of the
VikaD [51]

Answer and Explanation:

To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:

  • <u>pH level test</u>

pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.

<em>pH is acceptable in a range of 6.5 to 8.2.</em>

  • <u>Nitrates and Ammonia (NH3) levels</u>

Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.

Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.

<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.

<em>Less than 0.1 </em>indicates a healthy alligator pond.

  • <u>Bacterial coliform test</u>

This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.

If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
