Answer:
The correct option is C) Continental shelves
Explanation:
The continental shelf can be described as a part of a continent which is submerged in shallow water. This shallow water is known as a shelf. Hence, the name continental shelves.
Rich deposits of oil and natural gas can be present in this part of the sea. The continental shelves are of extreme commercial significance and are a commercial site for exploitation. The continental shelves can be rich in metallic and non- metallic ores and hydrocarbon products.
What did miller an ureys experiment provide evidence for
Answer/ Explanation:
The Miller-Urey experiment simulated hypothetical conditions present on early Earth which attempted to investigate the origin of life.
It used a collection of glass tubes and vessels containing water, hydrogen, methane and ammonia, which were believed to be the main components of the atmosphere on early earth. The earth's atmosphere was simulated using electrons, heat and cycling of the chemicals.
The experiment showed that this was sufficient to produce amino acids, the building blocks of proteins, which carry out essentially all living processes.
A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
A. 7.5 Feet
B. 6 Feet
C. 12 Feet
D. 3 Feet
A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of 7.5 feet.
A. 7.5 feet
Explanation:
Wave base defines the depth of the water when it is in still condition.
Wave base is half of wavelength.
Wave base = wavelength/2
Given,
Wavelength = 15 feet
So, wave base = 15 feet/2 = 7.5 feet
When the wave height is divided by wavelength then it gives the steepness of the wave.
Therefore, the wave base is 7.5feet.
A prescribed burn is _______.

What is the relationship between mutation, the cell cycle, and cancer? Select all statements that apply.
A. Mutated genes typically allow cells to respond to checkpoint proteins that hat the cell cycle, thus avoiding formation of tumors.
B. As a result of unregulated cells, cells may become cancerous, meaning that the cells grow and divide uncontrollably.
C. Cancerous cells may form malignant tumors that invade and destroy surrounding healthy tissue.
D. Mutated, defected genes may cause cells to become unable to respond to signals that regulate the cell cycle.
Final answer:
Mutation, the cell cycle, and cancer are closely linked since mutations in genes controlling the cell cycle can cause unregulated cell division and lead to the formation of tumors. Specifically, such mutations can disrupt cell cycle checkpoints and create non-functional regulatory proteins, leading to cancerous growth.
Explanation:
The relationship between mutation, the cell cycle, and cancer is crucial to understand the development of cancerous cells. To address the statements provided:
B. As a result of unregulated cell cycle, cells may become cancerous, which means the cells grow and divide uncontrollably.C. Cancerous cells can form malignant tumors that have the potential to invade and destroy surrounding healthy tissue. D. Mutations in genes may lead to cells becoming unable to respond to signals that regulate the cell cycle, contributing to uncontrolled growth.The mutation of genes involved in the cell cycle can lead to the production of non-functional proteins, disrupting cell cycle control and potentially leading to the formation of tumors due to uncontrolled cell division. This loss of regulation can cause cells to bypass the mechanisms that would typically halt their division, allowing them to proliferate and potentially form cancerous growths.

Why is it better to describe ion formation as a “transfer of electrons” rather than as “losing and gaining” electrons?
Explanation:
This is because the atom that ’donate’ the electrons and the one that ‘accepts’ the electrons – to become ions – will share an electrostatic association and form an ionic bond. So in reality, the atoms are only transferring electrons between themselves rather than “losing and gaining” electrons. When the ionic bonds are broken, such as in chemical reactions, the atoms go back to neutral (regain their electrons) and form new associations with other atoms to form new compounds.

It is better to describe ion formation as a transfer of electrons rather than ''gaining and losing'' electrons because;
An atom becomes a cation after losing an electron to another atom while the atom gaining the electron becomes anion.
Usually, atoms could gain or lose electrons when they react with other atoms or chemical species.Now, when an atom loses an electron as a result of its' reaction with another element or chemical specie, the lost electron is transferred to the other atom it is reacting with.Thus, one atom is gaining an electron while another is losing that electron. And when there is this type of losing and gaining of electrons, it is called transfer of electrons because because the two atoms having this electron transfer relationship will form an ionic bond after the transfer.Thus, since the two atoms form an ionic bond by formation of an ion, we can't say they are just losing and gaining electrons because that process leads to the formation of an ion and it is transfer of electrons that causes formation of ion.Read more at; https://brainly.com/question/15352211

the development of the modem atomic model,
Answer:
The one major change that occurred was the placement and organization of the electron. Rutherford's model identified that the electrons were at a distance from the nucleus, Bohr's model identified that the electrons occurred at levels that related to their available energy, and the modern atomic model shows that electrons are located in a predicted area but cannot be identified in a specific point.
Explanation: Sample Responsewhich observation proves that a cell is eukaryote
The observation that will prove that a cell is eukaryote is, the presence of genetic material within a well defined nucleus which is separated from the cytoplasm by the double layered nuclear membrane.
Explanation:
Cells can be prokaryotic or Eukaryotic depending on the presence or absence of nucleus in them.
Bacteria,archaebacteria and cyanobacteria are prokaryotic and all other known higher organisms are eukaryotic.
The feature that differentiates a prokaryotic cell from an eukaryotic cell is the absence of a distinct nucleus in them.
Eukaryotes have their genetic material enclosed by a double layered nuclear membrane while prokaryotes have their genetic material laid free in their cytoplasm.
The another difference is the lack of membrane bound organelles in prokaryotes which are present in eukaryotes.
Some eukaryotic cells lose nucleus at maturity, but they have it in their premature stages. For example, Red blood cells of humans.
This species of bacteria accounts for 12%-15% of all infant meningitis cases. It can grow at low temperatures, making the storage of leftover baby food and bottles especially dangerous.
The bacterial species, Listeria monocytogenes, accounts for 12%-15% of infant meningitis cases.
Explanation:
Listeria monocytogenes is a group B strep gram-negative bacteria, one of the main causes of meningitis.
This species is psychrotrophic in nature which means that it can grow at low temperatures like refrigerator temperature and mostly found in areas with a temperature around 15-20 degrees Celsius.
These organisms also become psychrotolerant or psychrophiles and can grow at places where the temperature fluctuates.
This is the main reason for the spoilage of food stored in a refrigerator. So leftover baby foods, bottles stored in a refrigerator can be contaminated with these species.
When the infants ingest the contaminated food or use the bottle, they also get infected. Listeria monocytogenes cause meningitis in infants especially who are immunocompromised infants.
Which part of an electric circuit resists the flow of charge when it changes electrical energy into other forms of energy?
A. battery
B. copper wires
C. switch
D. light bulb
Answer:
D. light bulb is the most appropriate answer
Explanation:
In an electric circut, presence of light bulb would convert the electric energy (flow of electrons) into light energy (photons). It will also resist the flow because to glow a bulb, electric energy will be required. This principle is also applied to all home based appliances where electric energy is used for several purposes.
Up to some extent, flow of electric energy in copper wires will also result in the loss of energy in the form of heat which is due to natural resistance of metal atoms.

If a person adds benzidene to cells grown in a test tube. Within minutes, she see’s the cells energy level fall and the metabolism in the cell comes to a stop. Which organelle does benzidene act upon?
A. Nucleus
B. Mitochondria
C. Endoplasmic Reticulum
D. Ribosome
Answer:
B. Mitochondria
Explanation:
Mitochondria are known as the power house of the cell. They are the sites of cellular respiration that breaks down glucose into energy molecules such as ATP and energy storage molecules such as NADH and FADH2.In this scenario, since the cell's energy levels fall and metabolism ceases, the organelle most likely affected is the mitochondria.If mitochondria are affected, glucose will not be metabolized to ATP and the cell will not have sufficient energy for cellular functions.3.

Muscular and skeletal systems:
Muscular systems:
Muscular systems are systems that involves three major muscles in its system which are described below,
Skeletal muscleCardiac muscleSmooth muscleThe functions of these three muscles are together makes the muscular system.
Skeletal muscle:
The skeletal muscles are like other striated muscles which are majorly composed of muscle fibers containing the myofibrils, which are majorly composed of sarcomeres.They are majorly involved in supporting the bones and the movement of human body.There are around 639 skeletal muscles in the entire body of a human being.Cardiac muscle:
Cardiac muscle are involuntary muscles that are found near the heart. They are controlled by the sinus node.Smooth muscle:
Smooth muscle are muscle that are found around the walls of organs such as intestines and stomach. They function automatically without any awareness.Thus these three are the major muscles that put up together muscular system and there play a major role in various body functions such as Mobility, posture, stability and other related functions.Skeletal system:
Skeletal muscles are voluntary muscles that support the skeleton and helps in moving the bones. These skeletal muscles gets contracted due to some reactions which inturn causes movement in the body and hence it is helpful in the functioning of body movement.Their other functions involve nutrition and temperature regulation.Both muscular and skeletal systems play a major role in the functioning of the human body and act as the prominent system that is necessary for a healthy human body.
which is not true of gene expression?
a. it creates different dna within each of your cell types
b. it explains how a cell functions
c. it is the specific combination of genes that are turned on or off
d. it occurs because of cellular signals within your body
All cells in an organism have the exact same DNA, despite the fact that they might express different genes. The incorrect statement about gene expression is that it results in different DNAs in different kinds of cells.
Explanation:The statement that is not true about gene expression is: it creates different DNA within each of your cell types. This statement is false because all cells within a single organism have the same DNA. The different cell types in your body (like the cells in your brain versus the cells in your liver) do not have different DNA. What distinguishes different cell types is the specific combination of genes that are turned on, or expressed, in that cell type, not a different DNA.
Gene expression refers to the process by which the information encoded in your genes is used to create functional gene products, such as proteins. It does not, however, create different DNA within each of your cell types. Rather, different combinations of genes are turned on or off in different cell types, leading to the specialization and functionality of each cell.

1. Describe what would happen if an organ in your specific organ system stopped working.
(Respiratory System)
If an organ in your specific organ system stopped working. then the other organs will try to rectify the issue and attempt to make a balance state known as homeostasis.
Explanation:
The organs are the important things that make up the functioning of an organ system. Every organ system in the human body are inter dependent on each other's function. For example circulatory system and the respiratory system. If the organs of an organ system fails, then the other organs will try to match the particular organ's function thereby reaching a state of balance.
This process of getting a state of being balanced in a human body human body is called homeostasis. The important organs for respiratory system includes larynx, pharynx, nose, lungs, bronchi and trachea. When there occurs a failure of one organ occurs the other organs will try to do the function to reach a balance within the organ system.
Sample Response: The brain, through the nervous system, sends signals to the muscular system, causing the muscles to move rapidly. This rapid motion produces heat in the body and is observed as shivering. The brain also sends signals to the muscles right beneath the skin. These muscles shorten and tighten, causing the hairs on the skin to stand up. When the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm.

Which process in plant physiology could not occur if the opening of the undersides leaves are closed?
A)photosynthesis
B)phototropism
C)reproduction
D)respiration
A) Photosynthesis will stop if the openings on the underside of the leaves are closed.
Explanation:
Photosynthesis produces sugars (glucose) by using carbon dioxide and water in presence of sunlight and chlorophyll. And oxygen is produced as a bye product of photosynthesis.
For the process of photosynthesis to take place continuously, it is very necessary that a continuous supply of Carbon dioxide and water is maintained into the cell.
Carbon dioxide enters the cell by the process of diffusion. The gases diffuse in and out of the plant tissue through the small openings on the surface of the leaves. These openings are called stomata.
If stomata remain closed then the diffusion of gases will cease . As a result photosynthesis will stop due to lack of raw material. Soon the plant will use up the reserve food and starve to death.
