View Available Hint(s) Why are liver extracts used in the Ames test? A liver extract is necessary for the bacteria to produce histidine revertants. Liver enzymes activate the bacterial enzymes. Liver enzymes may activate some innocuous compounds, making them mutagenic. The bacteria require the nutrients present in the liver extract for growth.

Answers

Answer:

Part A: False

Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic

Explanation:

The Ames test, also known as Salmonella typhimurium reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).

Number the steps from when a stimulus is received to when the body reacts.
_____ The stimulus is received by sensory receptors.

_____ Motor neurons cause muscles to contract so the body can react to the stimulus.

_____ The brain processes the information through interneurons.

_____ Interneurons transfer response information to motor neurons.

_____ Sensory neurons carry stimulus information to the brain or spinal cord.

Answers

Answer:

The correct answer is -

1 - The stimulus is received by sensory receptors.

2 -  Sensory neurons carry stimulus information to the brain or spinal cord.

3 -  The brain processes the information through interneurons.

4 -  Interneurons transfer response information to motor neurons.

5 - Motor neurons cause muscles to contract so the body can react to the stimulus.

Explanation:

In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.

These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.

Compare primary succession and climax community. Be sure to identify how long-term survival of species is dependent on resources that may be limited.

Answers

Answer:

Primary succession is the colonization of species of organisms on life-less barren lands after a volcanic eruption, newly formed land, or sand dunes. Lichens and mosses are the known primary succession community of organisms that helps in developing conditions for secondary succession by breaking rocks and providing soil.

After a fair amount of time, there are new species of organisms that grow and colonize in the land and these are, and ultimately the community becomes fairly stable. A climax community is a more stable, mature community that undergoes little or no change which can live for hundreds of years on the land.

The long-term survival of species is dependent on various kind of resources that may be limited, this can be explained by the lichens and mosses that have enough amount of nutrition and resources during primary succession but as new organism comes with complex structure and competes with these lichens and mosses their number decline due to limited amount of resources.

The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.

23%

Explanation:

According to Chargaff's law A = T and G = C

T = 27%

A = 27%

27 + 27 = 54

characteristics.
D. If a person takes at least one vitamin per day, then it will reduce a
person's level of tiredness.
HELP PLEASE!

Answers

Answer: Organisms evolve over time due to changes in heritable physical characteristics.

Explanation:

There are a few things to look for when distinguishing between a nonscientific theory and a valid scientific theory. One thing to consider is if there are any published literature, experimental studies, and data available to support the theory. Most scientific theories have data and information tied to them. Another factor to examine is who has developed the theory. A scientific theory will always be supported by evidence with large quantities of data and testing. An example of a scientific theory is the theory of evolution, which observes changes in heritable physical traits over time in an organism. A hypothesis might be that all organisms evolve at the same rate.

Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.

What is evolution?

Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations.

According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.

These characteristics are easily trasfered from one generation to other generation.

Therefore, Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.

How does a fire help grasslands?

Choose all that apply

Answers

Answer:

In most grassland ecosystems, fire is the primary mode of decomposition

Explanation:

Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.

A fire helps grasslands through the following:

Keeps trees from overtaking the grasses.Preserve biodiversity.

What is Fire?

This is the visible aspect of combustion of fuel and other materials to produce heat and flame.
