What is the independent and dependent variable? Two groups of students were tested to compare their speed working math problems. Each group was given the same problems. One group used calculators and the other group computed without calculators
__________________________

Answers

Answer 1
Answer:

The dependent variable is the one that depends on the value of some other number. ... Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called A) micelles. B) liposomes. C) vacuoles. D) bilayer membranes. E) none of the above

Answers

Answer:

D) bilayer membranes

Explanation:

Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.

Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Answers

Answer:

Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.

Explanation:

The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.  

So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change. We should not kill any animal.We should decrease the use of plastics.

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question

Answers

Answer:

Due to inclusion of more steps of photosynthesis.

Explanation:

My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.

Answer:

This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

An object with a mass of 12.59 grams was immersed in water in a graduated cylinder. The volume of the water before was 56.7 mL. After the object was placed in the water, the volume read 63.0 mL. If density = mass/volume, calculate the density of the object to the correct sig figs.

Answers

Answer:

[tex]\boxed {\boxed {\sf \rho \approx 2.00 \ g /mL}}[/tex]

Explanation:

The density is the mass per unit volume. It is calculated using the following formula.

[tex]\rho = \frac{m}{v}[/tex]

The mass of the object is 12.59 grams.

The volume was found using water displacement. A known quantity of water was placed in a graduated cylinder (56.7 mL), then the object was added and the water level was recorded again (63.0 mL)The volume of the object is the difference between the initial water volume and the final water volume.

v= final water volume - initial water volume v= 63.0 mL - 56.7 mL v= 6.3 mL

Now we know the mass and volume of the object and we can substitute the values into the formula.

[tex]\rho = \frac{12.59 \ g }{6.3 \ mL}[/tex]

Divide.

[tex]\rho = 1.998412698 \ g/mL[/tex]

The original measurements have 4 and 3 significant figures. We always round our answer to the least number of sig figs, which is 3. For the number we found, that is the hundredth place. The 8 in the thousandth place tells us to round the 9 up to a 0 (hundredth place), then the 9 up to a 0 (tenth place), and the 1 up to a 2 (ones place).

[tex]\rho \approx 2.00 \ g/mL[/tex]

The density of the object is approximately 2.00 grams per milliliter.

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).

Answers

It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.

A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.

In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;

A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.

Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.

Answers

Answer:

they obtain oxygen from water through gills

Explanation:

Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.

This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

<< Read Less

Answers

Answer:

Here's a better answer.

There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.

In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.

Next up, the fossil record provides evidence that supports common ancestry and evolution.  The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

Explanation:

The various pieces of evidence that support common ancestry are homologous organs, fossil records and embryological studies.

What is common ancestry?

The phrase "common descent" in evolutionary biology refers to a particular group of species' shared ancestry. The creation of new species from an original population is a component of common descent. Two creatures are considered to be closely related if they have a recent common ancestor.

In contrast, molecular genetic techniques can also be used to establish shared ancestry from a single universal ancestor of all living things. Natural selection and other factors, such geographic isolation, are considered to have contributed to many speciation episodes during this development from a universal common ancestor.

According to the common ancestry idea, every living thing descended from a single progenitor. Hence, the Theory of Common Descent contributes to our understanding of why traits in species living in different geographic regions vary, why some traits are highly conserved across broad animal classifications (such as vertebrates or tetrapods), why seemingly unrelated species (such as birds and reptiles) share hereditary physical and genetic traits, and why successfully adapted organisms typically have more offspring.

Therefore, embryological studies, fossil studies and homologous organs can help in the study of common ancestry.

Why are coral reefs important to ocean life? Coral reefs take carbon dioxide out of the water and secrete it into their skeletons. Corals provide an important cleaning function by filtering debris from the water. Corals are an important link in the benthic food chain. Coral reefs provide food, shelter, and breeding grounds for thousands of marine organisms. Coral reefs grow upward to near sea level, providing shallow zones for benthic organisms.

Answers

Coral reefs are important becase they provide an important ecosystem for underwater life, they also not only protect the underwater world but also are safety as well it works as a buffer and it protects are coasts form waves , storms, and floods. Also the coral reefs themselves teem with diverse life thousands can be found in just one reef.

Sometimes the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. What is a likely explanation for why nothing happened in your experiment

Answers

Answer:

Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone

Explanation:

Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.

At the time Hutton proposed his ideas about the age of rocks, how old was Earth believed to be by most people in Scotland?

Answers

Answer:

In the late eighteenth century, when Hutton was carefully examining the rocks, it was generally believed that Earth had come into creation only around six thousand years earlier (on October 22, 4004 B.C.

James Hutton was a Scottish naturalist and geologist who discovered the age of the earth. The earth was believed to be 6000 years old by the Scottish people.

Who was James Hutton?

James Hutton is the father of modern geology and was involved in the discovery of the earth's age and the soil formation from the parent rocks. He made his contribution to discovering the age of Earth based on his observation rather than on assumptions.

Before he discovered the earth age, it was believed by the Scottish people that the planet was six thousand years old. He discovered the process of soil formation by weathering the parent and bog rocks that accumulated as sediments over years and allowed the discovery of the planet's age.

Therefore, it is believed that the earth was 6000 years old.
