Norman thinks that the brain function of students suffers when they receive less sleep. He predicts that students who get less sleep before an exam will receive lower test grades. To investigate his idea, he tests two groups of chemistry students. Group 1 receives four hours of sleep, while Group 2 receives the recommended eight hours of sleep the night before the exam. Both groups consume the same foods before testing and take the same exam in the same room. The room has a constant temperature and level of light for all students. What is the independent variable in Norman's investigation?
Answers
The independent variable is the amount of sleep the students get. The independent variable is what you change in an experiment. Since one group received 4 hours of sleep and the other group received 8 hours, that is the independent variable.
The range of grades students receive on their exam will be the independent variable in Norman's investigation.
What is an independent variable?The term "independent variable" means exactly what it seems like. It is a variable that is independent of any other variables you are attempting to measure. For illustration, age could be an independent variable.
A dependent variable is one that keeps changing as a result of the manipulation of the independent variable.
It's the outcome you're after, and it "depends" on your independent variable. Dependent variables are also known as Response variables in statistics.
In Norman's study, the independent variable will be the range of grades students receive on their exams.
Thus, this is the independent variable in the investigation done by Norman.

Which of the following situations accurately describes a difference between a food chain and a food web?
Answers
Explanation:
Food chain is the chain in which the organisms of higher trophic level feeds on its immediate lower trophic level. Plant is the autotroph i.e., it produces its own food and animals and insects of higher trophic level feeds on it.
Ten percent of energy is passed from one trophic level to other trophic level as some portion of the energy is to carry out metabolic activity. Food web is interlinking of numerous food chains.
compare protons ,electrons, and neutrons with respect to location within atoms, eletric charge and mass
Answers
Answer:
Protons are positively charged, Electrons are negatively charged, and Neutrons are neutrally charged as in no charge positive or negative.
Protons and neutrons are in the middle (nucleus) of the Atom while the electrons are in shells or orbitals that surround the nucleus of an atom.
Protons have +1 mass, electrons have -1 mass, and neutrons have 0 mass.
- Que
Protons (+1 charge, 1 amu) and neutrons (no charge, 1 amu) are located in the nucleus, while electrons (-1 charge, approx. 0 amu) orbit the nucleus. The mass of protons and neutrons is about 1836 times greater than the mass of an electron. These subatomic particles define the properties and chemical behavior of elements.
Protons, neutrons, and electrons are the three main subatomic particles that make up an atom. Protons have a positive charge of +1 and, along with neutrons, are found in the atom's nucleus. Neutrons are electrically neutral and have no charge. Both protons and neutrons have a mass of approximately 1 atomic mass unit (amu). The mass of protons and neutrons is nearly the same, and they constitute the bulk of an atom's mass. Electrons, on the other hand, orbit the nucleus in orbital clouds and have a negative charge of -1. They have a negligible mass, approximately 0 amu, which is about 1/1836 times the mass of a proton.
The differences in their location within the atom, electric charge, and mass define many properties of elements and their chemical behavior. While protons determine the element's identity and its positive charge balances the negative charge of electrons, neutrons provide stability to the nucleus, and electrons are involved in chemical bonding and reactions.
A hypothetical organ has the following functional requirements: (1) the ability to resist surface abrasion and mechanical stresses; (2) the ability to contract involuntarily when stimulated by cells of the nervous system; and (3) the ability to resist tension in many different planes of force. The organ needs one tissue to carry out each of these requirements, and it also needs one tissue to "glue" all other tissues together, and one tissue to stimulate the contracting cells. What are the five tissues that will make up this hypothetical organ? Justify your choices.
Answers
Answer:
The five tissues needed that could make up this hypothetical organ are stratified squamous epithelial tissue, smooth muscle tissue, dense irregular connective tissue, loose connective tissue, and nervous tissue.
Explanation:
Ability to resist surface abrasion and mechanical stressesStratified squamous epithelial tissue
This consists of scale-like cells stacked together in layers that provide a barrier that is resistant to abrasions and wear-and-tear. This is also the most common type of stratified epithelium in the body. The top layer of this tissue has two types: keratinized, lined with dead cells with keratin, and non-keratinized, also with dead cells but without the keratin. In the human body, the skin is composed of stratified squamous epithelium.
Ability to contract involuntarily when stimulated by cells of the nervous systemSmooth muscle tissue
Smooth muscle, known for its non-striated appearance, is a kind of involuntary muscle cells that are stimulated by neural signals by the autonomic nervous system, hormones, and local factors such as a wall stretch of a certain organ, inflammation of visceral/parietal organs, etc. In the human body, this is mostly found in the walls of blood vessels and organ systems.
Ability to resist tension in many different planes of forceDense irregular connective tissue
This is a kind of connective tissue made up of collagen fibers arranged randomly. This creates greater strength and support in all directions. It can also return to its original shape even after stretching.
One tissue to "glue" all other tissues togetherLoose connective tissue
Also known as areolar tissue, it is loosely made up of collagen, elastin, and reticular fibers, and lots of ground substance. It is arranged in a web-like fashion and serves as the "cement" which fills in spaces between tissues.
One tissue to stimulate the contracting cellsNerve tissue
It is a specialized kind of tissue responsible for communication within the body. It transmits and receives signal impulses throughout the body. The 2 types of nervous tissues are neurons and neuroglia.
The hypothetical organ's structure would include epithelial tissue for abrasion resistance, muscle tissue for involuntary contractions, connective tissue for tension resistance and structural cohesion, and nervous tissue for stimulation of muscle contractions.
The five tissues that would make up this hypothetical organ based on the given functional requirements are:
Epithelial tissue, since it can resist surface abrasion and mechanical stresses, meets the first requirement.Muscle tissue, especially smooth muscle, has contractility and can contract involuntarily when stimulated by the nervous system, fulfilling the second requirement.Connective tissue, because it has toughness and pliability, allows it to resist tension in multiple planes of force, addressing the third requirement.Another role of connective tissue is to 'glue' all other tissues together within an organ, ensuring structural integrity.Nervous tissue would be necessary to coordinate the contractions of the muscular tissue, thus fulfilling the role of stimulating the contracting cells.The arrangement of these tissues is crucial as they form the structural and functional basis of the hypothetical organ, ensuring it performs its specific tasks effectively.

Answers
Answer:
A very acidic pH level is 1, and a very basic pH level is 13.
I'm not sure I understand about your ratios, whether they are the choices or just numbers.
Explanation:
On the pH scale, the more you go to the left, the more acidic the solution is. Numbers below 7 are considered acidic, and the lowest number is the most acidic. The more you move to the right, the more basic or alkaline the solution is. Numbers above 7 are considered basic. So the higher the number of that side of the scale, the more basic stuff is. 7 is considered neutral.

what is the independent variable?
Answers
Control group: people not exposed (sample b)
Dependent variable: skin cancer
Experimental group: (sample A)
Answer:
The amount of UV light exposure.
Explanation:
The independent variable is the one variable that an individual must change during an experiment in order to investigate or test the dependent variable. Basically their relationship to the experiment or between themselves can be easily remembered through their names: The independent variable is the one that's controlled by the researcher and therefore does not depend on other variables from the experiment (amount of UV light), the dependent variable depends on the independent variable since its often the result from the latter's variations (cases where people developed skin cancer) and finally, the controlled variable is the one that's kept the same throughout the experiment (Time exposed to sunlight within group A or method through which patients were tested for skin cancer).

A

B. They create a selectively permeable membrane.
C.
They can work together to perform chemiosmosis.
D.
They form a membrane that is impermeable to chemicals.
Answers
Answer:
B i hope this help
Explanation:
The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.
The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.
Phospholipids are particularly suited to serving as membranes because they create a selectively impermeable membrane, as option B shows.
Why are phospholipids able to create impermeable membranes?Due to its composition with fatty acids.Because of its hydrophobic tail.Phospholipids are molecules formed by fatty acids and alcohol. Fatty acids form the tail of these molecules and it is a hydrophobic structure that does not allow mixing with aqueous substances.
These tails are able to form a semipermeable structure that is very useful to maintain the selectivity of biological membranes, and controlling the entry and exit of elements.
All this can be seen in option B.

First statement best describes the relationship of photosynthesis and energy.
Answer: Option A
Explanation:
All living things need food to survive. The plants prepare their own food through the process of photosynthesis. The process of photosynthesis involves the absorption of light energy derived from the sun and it is converted into chemical energy by the leaves and stored in the form of glucose.
The photosynthesis takes place inside the leaf in the presence of water, carbon dioxide and sunlight. The leaves have tiny cell like structures called the chloroplasts and they have a green pigment called chlorophyll which absorbs the sunlight. It helps to release oxygen into the atmosphere rest are stored as nutrients for the plants growth.

D.

E.

Answers
You should face towards the water. Therefore, option (D) is correct.
What is sea and land breeze?The cool breeze comes from the direction of the water because of the temperature difference between the land and the water. During the day, the land heats up faster than the water due to its lower heat capacity. As the warm air above the land rises, cool air from the water is drawn in to replace it, resulting in a cool breeze blowing from the water towards the land.
Sea and land breezes are local winds that occur in coastal regions due to differences in temperature and pressure. During the day, the land heats up faster than the sea, causing the air above the land to warm and rise. This creates a low-pressure area over the land. At the same time, the air above the cooler sea remains relatively stable, creating a high-pressure area. The air flows from high pressure to low pressure, so cooler air from the sea moves towards the land, creating a sea breeze.
At night, the opposite occurs. The land cools down faster than the sea, creating a high-pressure area over the land and a low-pressure area over the sea. This causes air to move from the land to the sea, creating a land breeze. Sea and land breezes can affect the weather in coastal regions and can also impact local marine ecosystems.

Answer:
One of the ways that plant systems and tissues work together is in the transport of materials such as water, called transpiration. In transpiration, water is taken into the plant and then evaporates out of the leaves. First, water is taken in through pores in the dermal tissue of the roots and brought to the xylem of the vascular tissue. The vascular tissue then transports it up through the stem and into the leaves. Once in the parenchyma cells of the ground tissue of the leaves, photosynthesis and cellular respiration occur, using that water. The water is then released through guard cells of the dermal tissue into the atmosphere.
