Yes, the specific heat capacity of substances change when there is a change in temperature. At molecular level, the internal energy of a substance is stored in form of translational, rotational and vibrational energy. It has 3 degrees of freedom for each form of energy. In lower temperature ranges, say below 1000 degree celsius, vibrational energy is insignificant.
which atmospheric layer is least dense
The exosphere is the least dense layer of Earth's atmosphere because it is the farthest away from Earth and has the least amount of air molecules.
The exosphere is the least dense layer of Earth's atmosphere.
Here's why:
The atmosphere is made up of five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
As you move away from Earth's surface, the density of the atmosphere decreases. This is because gravity pulls the atmosphere towards Earth, so the closer you are to Earth, the more molecules there are to be pulled in.
The exosphere is the outermost layer of the atmosphere, and it is so thin that it is barely considered part of the atmosphere at all. The density of the exosphere is about 100,000 times less than the density of the air at sea level.
Because of its low density, the exosphere is very cold and has very little air pressure. In fact, the exosphere is so thin that satellites can orbit Earth within it without encountering much air resistance.
The question has eliminated one option exosphere that is only the correct answer.

List the three functions of kidney
Most notably, kidneys remove dangerous toxins and excess water from your blood and eliminate them through your urine. Kidneys also perform other amazing physiological feats, from regulating the amount of fluid in your body to controlling the salt content of that fluid. Here are three more amazing kidney functions.
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.
3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

How does studying the DNA of different types of organisms provide evidence that all life on earth is related?
All DNA of creatures is made from the same materials, and is largely the same. (Humans are less than 5% different than primates genetically)
Studying DNA of different species reveals that all life on Earth shares a common ancestor, due to universal genetic similarities. Genomics has enabled the construction of the 'tree of life' illustrating these relations. Molecular evidence, such as genome comparisons, helps us understand the evolutionary connections among diverse organisms.
Studying the DNA of different organisms provides evidence that all life on Earth is related because all extant life shares a common ancestor. This is visible in the fundamental similarities at the molecular level, such as the universal genetic code, the use of DNA to store genetic information, and the usage of similar molecular building blocks. Genomics and genetics have made it possible to construct the 'tree of life', a diagram illustrating the relationships among organisms by examining nucleic acid sequences that they have in common. This shows the deep connections across all living organisms, from the molecular level to larger structures and functions.
The genomes of various organisms show that they share a high degree of similarity in DNA sequences which code for proteins and other molecules. Through detailed analyses of these genetic codes, scientists have been able to determine homologies that imply a common ancestor. As evolution progressed, the genetic code established early in Earth's history evolved into the diverse life forms observed today. Additionally, molecular evidence of evolution, such as the comparison of genomes, sheds light on how evolution occurs and the relationships among species.

Final answer:
Learned behaviors are not inherited traits and are not passed from parents to their offspring. These behaviors are developed after birth, influenced by environmental factors and previous experiences, highlighting the adaptive nature of organisms.
Explanation:
The question asks whether learned behaviors are inherited traits, with the correct answer being that learned behaviors are not passed from parents to their offspring and are not inherited traits. Instead, learned behaviors are skills and responses that animals develop after birth, influenced by environmental changes and previous experiences.
This distinction is crucial in understanding the adaptive capabilities of organisms in response to their surroundings. Learned behaviors include imprinting, habituation, conditioning, and cognitive learning, enabling organisms to adapt to environmental changes. Unlike innate behaviors, which are instinctual and genetically programmed, learned behaviors can be modified and are not fixed.
Based on the theory of evolution, if a population possesses a large amount of genetic variety, what level of variety can be expected in the future for that same population? A. The population will maintain the same level of genetic variety. B. The population will tend to become extinct. C. The population will increase in variety over time. D. The population will become more specialized in one particular direction.
Answer:
C. The population will increase in variety over time
Explanation:
If a population has a high level of genetic variety, that will result in even grater genetic variations as the times goes on. With the increase in genetic variation in the population, gradually new species will start to emerge from it, thus speciation will occur. This will happen because the greater genetic variations will enable some of the population to be able to use some other food sources over time, and if that is advantageous than those individuals will start to slowly move in other direction, thus becoming a separate species.

Both pseudopods and flagella are used for movement. Pseudopods are temporary and used to engulf food, while flagella are hair-like structures used for locomotion in dinoflagellates.
Explanation:The question pertains to the comparison of pseudopods in sarcodina and flagella in dinoflagellates. The correct answer to the question is that both pseudopods and flagella are used for movement, but only pseudopods are used to engulf food. Pseudopods are temporary, foot-like extensions of the cytoplasm enabling sarcodina to move and capture prey. Conversely, flagella are long, hair-like structures that allow dinoflagellates to move through their aquatic environments. While flagella contribute to the locomotion of dinoflagellates, they are not involved in engulfing food.

A little boy blows air into a rubber glove and ties a knot at the end of it. He realizes that he wants the puffed-up glove to be bigger, but he's already tied a knot that he cannot untie.
According to the gas laws, what could the little boy do to increase the volume of air in the glove?
poke a hole in one of the fingers of the glove
place the glove in the sun
squeeze the fingers of the glove
place the glove in the freezer
squeeze the fingers of the glove because of imcrease pressure
Answer:
Place the glove in the sun
Explanation:
According to the ideal-gas law:
PV=nRT (1)
References:
P= Pressure
V= Volume
T=Temperature
n= Mol
R=Constant
As it is described , the amount of air inside the glove is constant, so R and n are constants and the ideal-gas formula can be re-written as follows:
V=aT/P (2)
Being "a" a constant.
We can see in (2) that the volume can be incresed directly by increasing the temperature or by lowering the pressure. So the correct answer is "place the glove in the sun" because the temperature of the air will be increased and the volume of the glove will be increased as well.
It is easy to think that by squeezing the fingers of the glove the volume is increased, but in this case the volume of the glove is decreased (because it hasn't got the volume of the fingers anymore) and the pressure is increased in consequence, making the rest of the glove swell in order to maintain the original volume.

The function of the light-dependent reactions is to:
a) build sugars
b) capture and transfer energy into a usable source
c) release carbon dioxide
d) form water molecules
Answer:
c
Explanation:
OPTION B. The main function of light-dependent reactions in photosynthesis is to capture and convert light energy into chemical energy (ATP and NADPH), which will then be used to build sugars in the light-independent reactions.
Explanation:The function of the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts in plants, is to capture and transfer energy into a usable form. During these reactions, light energy is converted into chemical energy, specifically ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). ATP and NADPH are then used in the light-independent reactions (the Calvin cycle) to build sugars.
The other options presented are not primarily functions of the light-dependent reactions. They do not directly form water molecules or release carbon dioxide yet contribute indirectly by capturing energy used in other processes that could involve these functions.

When a light wave is absorbed by an object what happens to the absorbed light energy
Answer:
The frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.
Explanation:
Final answer:
Absorbed light energy is typically converted into heat or another form of energy by the object absorbing it. Objects appear colored due to the reflection of certain wavelengths, while those absorbed contribute to energy transformation within the object.
Explanation:
What Happens to Absorbed Light Energy
When a light wave is absorbed by an object, the absorbed light energy is converted into other forms of energy, typically heat. This transformation is a result of light interacting with matter. For instance, pigment molecules in plants absorb visible light for photosynthesis, while materials like glow-in-the-dark plastics can absorb light energy and later re-emit it as phosphorescence. The energy from light that's absorbed can also contribute to an object's temperature increase.
Moreover, the absorption of light depends on the wavelengths of light and the material it interacts with. Objects appear colored because they reflect certain wavelengths while absorbing others. For example, a red apple appears red because it reflects red wavelengths and absorbs others.
According to what you have learned about the circulatory and respiratory systems, explain how and why your heart changed its rate?
Answer:
Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.
Explanation:
Your heart is continuously beating to keep blood circulating throughout your body.
So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.
And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.
Final answer:
The heart rate changes due to the autonomic nervous system's regulatory signals, based on the body's oxygen needs. The SA node controls these changes to ensure adequate blood circulation. External factors and the body's physical state directly influence the heart's operating rhythm.
Explanation:
The heart rate changes in response to the body's need for oxygen. During physical activities or stressful situations, the autonomic nervous system signals the heart to beat faster through the Sinoatrial Node (SA node), also known as the heart's pacemaker. This mechanism ensures that more oxygen-rich blood is circulated throughout the body to meet the increased demand.
Conversely, when the body is at rest or calm, the heart rate slows down, reducing the need for oxygenated blood. Factors such as physical fitness levels, emotional state, and even body position can influence heart rate. For instance, shifting from lying down to standing can cause a temporary increase in heart rate to maintain blood pressure and ensure adequate blood flow.
The heart, located within the circulatory system, is the central pump that drives blood through a network of arteries and veins, delivering nutrients and oxygen while removing waste products. It operates through rhythmic contractions controlled by intrinsic electrical impulses, regulated by the brain and hormones, illustrating the interconnectedness of the circulatory and nervous systems.
