Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.

identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?​

Answers

Answer:

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

Radiation does not have effect on strength of the mice

Explanation:

In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.

The control group is the group that does not receive treatment which is used to compare the effect of the treatment.

The control variable is another variable that must be held constant when performing the experiment.

Here the

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

What is the classification of virus​

Answers

Answer:

Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.

Many viruses attach to  host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.

The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.

Explanation:

not sure if this is what you are looking for

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.

What is Virus?

A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.

Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.

Class 1: Double-stranded DNA viruses.

This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.

Class 2: Single-stranded DNA viruses.

Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.

Class 3: Double-stranded RNA viruses.

Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.

Class 4: Single-stranded RNA viruses (positive sense).

Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.

Class 5: Single-stranded RNA viruses (negative sense).

Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.

Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.

Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.

Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.

Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.

Therefore, it is well described above.

Explanation: I got this question on khan academy.

The option that represents the activation energy of a catalyzed reaction is C. X; the activation energy is greater in an uncatalyzed reaction.

Activation energy simply means the minimum amount of energy that should be provided for compounds that'll result in a chemical reaction.

It should be noted that the activation energy for uncatalyzed conversion to the products will be more than that of the catalyzed reaction. In this case, X; the activation energy is greater in an uncatalyzed reaction.

A city is located in an area that has experienced 7.5-magnitude earthquakes in the past.
The city is considering building a new skyscraper.
Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude.
Then suggest a way to minimize the effects of future earthquakes on the skyscraper.

Answers

According to the scale, residents should expect major damage and the potential for the skyscraper to collapse if a future earthquake were to occur.
Ways to minimize future earthquakes impact on the skyscraper could be using stronger materials, creating better routes to quickly escape should an earthquake occur, and overall a more supported structure that can withstand the earthquakes magnitude.

the ability to maintain homeostasis

the ability to maintain homeostasis

the ability to grow and develop

the ability to grow and develop

the ability to adapt and evolve

the ability to adapt and evolve

the ability to reproduce

Answers

Answer:

Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.

According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.

Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.

Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.

a. Gene theory

b. Homeostasis

B

An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.

False

False

Humans began life as a single cell because we develop from a fertilized egg cell.

Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.

No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.

Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Senko was snorkeling while on vacation in the Cayman Islands with his family when a large sea turtle swam near him. Senko naturally did what any 12-year-old boy would do and decided to grab the turtle and go for a ride. That turtle ride, in some ways, has never ended. People find their passions in many different ways. Senko found his passion while riding on the back of a turtle when he was just 12 years old.Today, Senko is a conservation scientist at Arizona State University. He focuses his research and lifes work on marine resource sustainability. Can you guess what that includes? If you guessed sea turtles, you would be correct. In college, Senko majored in fisheries and wildlife science, and he also received a Master of Science degree in wildlife ecology. Much of the focus of his work is on saving endangered sea turtles.Sea turtles help keep the ocean healthy, and thus their well-being affects the entire ecosystem. They provide a natural regulatory system for the environment. For example, sea turtles eat seagrass, which helps it grow properly, and their unhatched eggs provide nutrients for plant life to keep beaches healthy. Sea turtles also provide a home for small animals that attach to their shells.Sea turtles are endangered because fishermen inadvertently catch them in their nets, which can cause the turtles irreparable harm. Senko came up with the idea to create solar-powered fishing nets so fishermen can readily see when they accidentally catch a sea turtle. Because the lights are solar powered, the fishermen do not have to maintain the lights or change the batteries. This technology has resulted in a 65 percent reduction in sea turtle catches thus far. Senkos goal is a 100 percent reduction.In "The Ride of His Life," what viewpoint is the author trying to communicate about Senko?Senko always knew his career would involve the ocean.Senko has a passion for working with sea turtles.Senko is an avid fisherman who wants to help save wildlife.Senko longs to be on the cutting edge of modern technology.
