compare protons ,electrons, and neutrons with respect to location within atoms, eletric charge and mass
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.

12. Which organelles are known as the "power plants"
of the cell because they transfer chemical energy
from food to compounds the cell can use?
a. mitochondria
b. ribosomes
c. lysosomes
d. vacuoles
The organelles known as the 'power plants' of the cell are the mitochondria. They convert the chemical energy from food into compounds the cell can use, through a process called cellular respiration.
Explanation:In biology, the organelles that are referred to as the 'power plants' of the cell are the mitochondria. These organelles are responsible for the critical task of producing energy for the cell. This process works by converting chemical energy found in the food we consume into compounds that the cell can use. This is achieved through a process known as cellular respiration. Other organelles, such as ribosomes, lysosomes, and vacuoles, each serve their unique functions, with ribosomes responsible for protein synthesis, lysosomes for waste disposal, and vacuoles for storage, but it's only the mitochondria that does the work of a cell's energy 'power plant'.

Explanation:
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.
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.

Imagine standing on a sandy beach on a warm, sunny day facing east. The sand and you are hot. You want to catch a cool breeze on your face.
Which way should you face?
A.
toward the land
B.
toward the north
C.
toward the south
D.
toward the water
E.
toward the sky
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.

6. Cell membranes are primarily composed of a double layer of phospholipids. Why are phospholipids particularly
well suited to serving as membranes?
A
They can be used to metabolize starches.
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.
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.

Which statement best relates to how the structure of a lipid influences the lipid’s function?
A phospholipid has a charged head and an uncharged tail.
Lipids contain fatty acids and glycerol.
The ends of the lipid are attached to each other.
A lipid is made up of a long chain of phosphorus molecules.
Answer:
The correct answer is B) Lipids contain fatty acids and glycerol.
Explanation:
Lipids are mostly found in the cell membrane, where its function is to make a barrier for protection and control. Therefore, its structure facilitates the formation of a bilayer with two different types of solubility, due to the glycerol heads (hydrophilic) and the tails made of fatty acids (hydrophobic) located in the exterior and interior face of the membrane and on the middle, respectively.

Answer:
Epidermis, in botany, outermost, protoderm-derived layer of cells covering the stem, root, leaf, flower, fruit, and seed parts of a plant. The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.
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.

What are the functions of the promoter sequence and the terminator sequence in DNA?
a, b, c, or d?
Answer:
A
Explanation:
Promoter region on DNA is the point on DNA where polymerase enzyme attaches so it can begin the translation of genes/operon downstream. Terminator region on the DNA is the point that causes the polymerase to terminate transcription. For example, the terminator regions may cause the transcribed nascent mRNA to form a hairpin structure at the terminator sequence hence causing the polymerase enzyme to detaches from the DNA strand.
Promoter sequence initiates transcription, while the terminator sequence ends it in DNA. Correct answer is 1. Promoter sequence begins transcription, while terminator sequence ends it.
Promoter sequence: A DNA sequence where RNA polymerase binds to initiate transcription. It determines when and where transcription starts. Consists of specific nucleotide segments recognized by RNA polymerase or regulatory proteins.
Terminator sequence: A DNA sequence indicating where transcription should end. It helps in the release of RNA polymerase and stops the addition of nucleotides to the RNA strand.
In summary, the promoter sequence begins transcription by providing a binding site for RNA polymerase, while the terminator sequence ends transcription by signalling the enzyme to detach.

what is the independent variable?
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).
