An experiment is designed to determine if wheat grows better when it is planted alone or with clover. The design calls for 3 pan

s of each treatment. Pans A, B, and C contain only wheat. Pans D, E, and F contain clover and wheat planted in alternating rows. Each pan contains a total of 100 seeds. All treatments contain the same type of soil, are planted in the same size pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. Use the passage in red to complete the following statement: The treatments planted with only wheat are the A. sample sizeB. The controlC. environmental variableD. null hypothesis

Answer: Option B

Explanation:

Usually in scientific experiments, at least one parameter is checked; here, the growth rate of wheat in two different conditions is being evaluated.

Hence, growth rate of wheat alone in pans A, B and C becomes the standard or referential control against which the experimental control (Wheat + clover) in pans D, E and F is evaluated, since both treatments are exposed to the same external conditions.

I hope this helps

Answer:

Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.

Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

Answer:

See explanation below.

Explanation:

1. Explain the difference in the roles of producers, consumers, and decomposers in the Everglades.

In the Everglades, producers would be all <u>species of organisms that are autotrophs such as different species of plants</u>. Consumers are categorized into three: primary, secondary and terciary consumers. <em><u>Primary consumers</u></em><u> feed on plants (e.g. insects), </u><em><u>secondary consumers</u></em><u> eat the primary consumers (e.g. mice or rats), while </u><em><u>tertiary consumers</u></em><u> are higher predators that eat the secondary consumers (e.g. racoons)</u>. Finally, decomposers are bacteria, archaeans, fungi, or worms that live in soil which decompose organic matter.

2. Based on your knowledge of how to classify living organisms, in what domain and kingdom do the producers, consumers, and decomposers belong?

In Biology, the three domains are Archaea, Bacteria, and Eukarya; while there are six kingdoms: Archaebacteria, Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

  • Producers, that is plants, belong to the Domain Eukarya and the Kingdom Plantae.
  • Primary, secondary, and tertiary consumers also belong to the Domain Eukarya and to the Kingdom Animalia as they are all animals and eukaryotes.
  • Decomposers are classified into the three domains: Archaea, Bacteria, and Eukarya. Bacteria belong to the domain Bacteria, archaeans belong to the domain Archaea, and worms and fungi belong to the domain Eukarya. On the other hand, decomposers are classified into Archaebacteria, Eubacteria, Protista (oomycetes), Fungi, and Animalia (worms).

3. How did energy travel in the Everglades BEFORE the alligators were removed?

Aquatic plants (producers) <-- bass <-- bluegill <-- gar <-- alligator

Aquatic plants (producers) <-- zooplankton <-- bass/bluegill <-- wood stork <-- alligator

Plants (producers) <-- cattle <-- alligator

Plants (producers) <-- insects <-- rats <-- racoons <-- alligator

4. How did removing the alligators from the food web change how energy flowed in the Everglades?

Once the alligators were removed from the food web, the populations that were once in decline began to recover because of the lack of predators. Consequently, the lack of alligators led to the uncontrollable growth of racoons, wood stork, and gar, which could also cause an alteration as they consume ecologically and economically important fish species such as the bass and bluegill.

5. How did the problem begin, and what action(s) should Ranger Imani take to solve this issue?

The problem began when the populations of alligator, an apex predator that sits at the top of the food chain, grew at an accelerated pace. This led to the uncontrolled predation of other organisms that are also fundamental to maintain an ecological balance. Therefore, Ranger Imani decided to humanely euthanize the alligators, which were preying upon them. This led to a huge increase in wood stork, gar, and racoon populations.

Alligators should not be completely removed because they help to maintain an ecological balance. Instead, Ranger Imani should work on controlling populations by implementing Wildlife Population Management strategies, such as sustainable fishing, to prevent a certain species population from reaching a high number of individuals in order to keep a healthy ecosystem where all populations are stable because removing all apex predators is not the appropriate strategy as it significantly alters the ecosystem.
