Lodgepole pine trees produce seeds in cones. The cones open after being exposed to high temperatures created by wildfires. How does this adaptation help the lodgepole pine survive?
A) It allows the lodgepole pine tree to make more seeds in cones that are hard to open.
B) It creates more wildfires for the lodgepole pine tree to reproduce.
C) It makes the seeds travel and grow in areas where there are no wildfires.
D) It helps the lodgepole pine tree to protect the seeds and to reproduce.
Answer:
D
Explanation:
A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.
Answer:
D
Explanation:
A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce. IS WRONG C) It makes the seeds travel and grow in areas where there are no wildfires. DEFINITLY NOT so that leaves it with D It helps the lodgepole pine tree to protect the seeds and to reproduce.

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.
Hope this helps!

Over a period of several decades ecologists conduct an investigation on the survival of a species of lizards
Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

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.

Answer c
Explanation:
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.

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%

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.
