Consider an experiment in which subjects are given a pill to test its effectiveness in reducing the duration of a cold. Which of the following is the best way to treat the control group.
A. Give the control group two pills instead of one.
B. Do nothing with the control group.
C. Give the control group a pill that looks like the test pill but does nothing

Answers

Answer 1

Answer:

c.

Explanation:

(comment if you need an explenation and I'll give it)

Answer 2

Give the control group a pill that looks like the test pill but does nothing is the best way to treat the control group. Option C is correct.

The best way to treat the control group in this experiment is option C: give the control group a placebo pill that looks like the test pill but does not contain any active ingredients. Here's why:

Ensuring Validity: A control group is used to establish a baseline for comparison. By giving the control group a placebo pill that looks identical to the test pill, researchers ensure that both groups experience the same psychological and physical conditions except for the presence of the active ingredient. This helps eliminate potential bias and confounding variables that could affect the results.

Blinding: Giving the control group a placebo maintains blinding, where participants do not know whether they are receiving the active treatment or the placebo. This prevents participants' expectations or beliefs from influencing the outcomes, enhancing the experiment's validity.

Placebo Effect: The placebo pill accounts for the placebo effect, a psychological phenomenon where participants experience improvements in their condition due to their belief in the treatment's effectiveness. By giving the control group a placebo, researchers can assess whether the test pill's effects are genuinely due to the active ingredient or influenced by participants' perceptions.

Ethical Considerations: It's important to provide some form of treatment to the control group to ensure they are not harmed or misled. Giving them a placebo pill with no therapeutic effect is an ethical way to include them in the study while minimizing potential risks.

Overall, using a placebo that mimics the appearance of the test pill ensures a controlled and rigorous experiment, where the effects of the active ingredient can be accurately evaluated. This approach maintains scientific integrity, valid comparisons, and ethical considerations.

por que un globo con aire se agranda al sol y se achica en la heladera

Answers

Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

Explanation:

A strain of bacteriophages was grown in BrdU. BrdU is a base analog, that when incorporated into DNA, causes the DNA to fluoresce yellow. Another culture of the bacteriophage strain was grown in media containing cysteine (an amino acid) linked to a red fluorescent molecule. Each strain of bacteriophage was allowed to infect unlabeled cells. Follow the patterns of fluorescence through infection. How would this experiment help prove that DNA is the genetic material

Rough endoplasmic reticulum (RER), series of associated leveled sacs, part of a nonstop film organelle inside the cytoplasm of eukaryotic cells, that assumes a focal part in the blend of proteins. The unpleasant endoplasmic reticulum (RER) is so named for the presence of its external surface, which is studded with protein-orchestrating particles known as ribosomes.

This element separates it hastily and practically from the other significant sort of endoplasmic reticulum (emergency room), the smooth endoplasmic reticulum (SER), which needs ribosomes and is associated with the union and stockpiling of lipids. RER happens in both creature and plant cells.

Answer: D: The distribution of many organisms has already shifted as a result of warming.

Explanation: I just took the quiz on FLVS

The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming

What is climate change ?

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.

____________________________________ use reduced, preformed organic molecules (usually from other organisms) as carbon sources, obtain energy from the oxidation of organic compounds, and use reduced organic compounds as their electron source.

Answers

Answer:

Heterotrophs

Explanation:

Heterotroph, in ecology, is an organism that consumes other organisms in a food chain. They acquire their energy by the controlled breakdown of preexisting organic molecules, or food.

¹All heterotrophs, use organic materials as their sole source of carbon. Heterotrophs use preformed organic compounds as their source of carbon. (Source: Brittanica)

Metabolic cycles in general—the extraction by organisms of useful ²energy and food molecules from environmental source material—can be described in terms of oxidation-reduction reactions

Heterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, lithoheterotrophs use inorganic compounds, such as ammonium, nitrite, or sulfur, to obtain electrons.

The genotype for the woman being normal should not have recessive alleles and only can be heterozygous or purebred dominant. It is possible only if the genotype is Ff and ff.

how does the liver help in maintaining homeostasis

Answers

Answer:

The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.

Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.  

Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.

Carbohydrates

Explanation:

Carbohydrates are energy-rich compounds made from carbon, hydrogen, and oxygen.

Plants and animals use carbohydrates. Cells use carbohydrates to get and store energy.

Plants contain cellulose, a carbohydrate, which gives them a rigid structure.

Why do living things need water, food, and space to live? To maintain homeostasis.

Answers

1.)Food- Food gives organisms energy and the raw materials needed to carry on life processes. Organisms use nutrients from food to replace cells and build body parts.

2.)Water- You could only survive for about three days without water. You get water from the fluids you drink and the food you eat.

3.)Air- Air is a mixture of several different gases, including oxygen and carbon dioxide. Most living things use oxygen in the chemical process that releases energy from food. Oxygen may come from the air or may be dissolved in water.

4.)Habitat- All organisms need a place to live that contains all of the things they need to survive. Some organisms, such as elephants, require a large amount of space. Other organisms may live their entire life in one place.
