Which is an example of a scientific theory?
A. On average, larger mammals sleep longer than smaller mammals.
B. If a plant receives pure water, then it will grow more than one that
receives salt water.
C. Organisms evolve over time due to changes in heritable physical
characteristics.
D. If a person takes at least one vitamin per day, then it will reduce a
person's level of tiredness.
HELP PLEASE!
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.

Babies with very low or very high birth weight are less likely to survive. The graph shows the percentage of babies born at different weights.
A graph entitled Percentage of Babies born at Different Weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. A small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds.
Which statement is a valid claim that could be made using the data in the graph?
Directional selection is occurring because the graph favors an extreme.
Stabilizing selection is occurring because the average is favored.
Disruptive selection is occurring because the two extremes are favored.
Biodiversity variation is occurring because there is an increase in trait variation.

Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box. Which table correctly lists the characteristics of the organisms in the two kingdoms?
Answer:
B
Explanation:
C table correctly lists the characteristics of the organisms in the two kingdoms. So, the correct option is C.
What is Five kingdom classification?The system of biological kingdoms is the way in which science classifies living things in order of evolution according to their ancestors which means all species that make up these five large groups. Some recent theories divide them further into six or seven showing the common ancestors and sharing some of their genes which belong to the same family tree.
Along with the kingdoms of living things, there are other taxonomic categories within the same classification system, such as, for example, domain, kingdom, phylum, class, order, family, genus, and species.
Therefore, the correct option is C.

Explanation:
A group of students wants to study the structures of animals in the desert. One question they should ask is-
How long do the animals live?
Can you buy the animals in pet stores?
How do the animals satisfy their need for water?
How many offspring do the animals have?
From studies and research, I believe the proper question would be:
"How do the animals satisfy their need for water?" or "How long do the animals live?"
Explanation 1:
When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.
Explanation 2:
Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.
Side Note: Offsprings mean children.

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.
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.

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.

All compounds that have been found to be mutagenic in the Ames test are also carcinogenic. View Available Hint(s) All compounds that have been found to be mutagenic in the Ames test are also carcinogenic. True False Submit Part B Why are liver extracts used in the Ames test? 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.
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).
In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine
Answer:
23%
Explanation:
According to Chargaff's law A = T and G = C
T = 27%
A = 27%
27 + 27 = 54
100 - 54 = 46
46/2= 23
So 23%
