2) Stomata are flanked by them...

Transpiration is controlled by opening and closing of the stomata, which is accomplished through swelling or shrinking of guard cells.

Hypothesis: If the porosity of three soils are tested, then red clay soil will have the lowest porosity.

Answers

Answer:

This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.

*Independent variable: DIFFERENT SOILS

*Dependent variable: Porosity

Explanation:

- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.

- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.

É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.

(English )Is it correct to say that energy follows a linear flow in the food sections, while nutrients are constantly recycled? Explain.

(Portuguese) É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.

Answer: Yes.

Responder: Sim.

Explanation: (*English) A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.

(*Portuguese) Uma cadeia alimentar é uma sequência linear de organismos através dos quais nutrientes e energia passam enquanto um organismo come outro; os níveis na cadeia alimentar são produtores, consumidores primários, consumidores de nível superior e, finalmente, decompositores.

The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.

Answers

About the question:

You will find the diagram used to answer the question in the attached files.

Answer:

D) Some of the bacterial population was resistant to this antibiotic.

Explanation:

The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.

The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.

In the exposed example we have,

Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.

The population was treated with antibiotics.

Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.

The mutated phenotype gets to survive under the effects of the chemical.

Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.

The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.

Day 4Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.

Soil organisms, such as mycorrhizal fungi, impact the rate of succession in ecosystems. Mycorrhizal fungi have a mutualistic relationship with various species of plants and increase the plant growth and survival. Sand dunes often lack mycorrhizal fungi, and a researcher wanted to determine the effect of adding mycorrhizal species to sand on disturbed beaches on grass growth. The researcher set up various mycorrhizal communities at disturbed beaches in different locations on the east coast of the United States. Identify the independent variable in the study.

Answers

Answer:

The amount (number) of mycorrhizal fungi

Explanation:

In a scientific experiment/study, the independent variable is the variable that isn't changed by other variables, while the dependent variable is the variable that is being measured during the experimental procedure. The independent variable is manipulated by the researcher (in this case, the amount of mycorrhizal fungi), thereby affecting the dependent variable (in this case, grass growth). In consequence, a variable is dependent because it 'depends' on the independent variable.

or students
C. Whether the content has been peer

D. Whether the site is biased toward the

Answers

Answer: I think the answer is B.

Explanation:

Some animals have an organ called the gizzard. The gizzard is muscular and helps to crush up hard food. Earthworms and many birds, including chickens, have gizzards. Chickens swallow small rocks that help the gizzard to grind up food. Did plant-eating dinosaurs have gizzards too? No one has found an actual dinosaur gizzard, but they have found small piles of round rocks inside dinosaurs’ ribcages.

Based on its function, the gizzard is part of the
system.
