Answer:
The correct answer will be- tension
Explanation:
Centripetal force is the force acting on the object moving in a circular path with direction towards the center. The centripetal force causes the object to follow a curved path.
Three forces together act on the string with key: Tension (a force acting on the key chain due to string), gravity (the downward force), and friction (resisting force). Out of these the main source of action of centripetal force is the "tension" applied by the string on the key-chain.
Thus, tension is the answer.

which of these are not examples of matter
-carbon dioxide
-energy
-heat
-jelly
-sponge
Energy is not an example of matter. So the correct option is B.
What is the matter?A material called matter is made up of several kinds of particles that take up space physically and have inertia. The many sorts of particles each have a unique mass and size according to the fundamentals of current physics.
The electron, proton, and neutron are the three types of material particles that are most well-known. Atoms are made up of combinations of these particles.
Quarks and leptons, which are both regarded as elementary particles since they are not formed of smaller units of matter, are the building blocks of matter. Protons and neutrons are formed through the interaction of quarks, which are groupings of subatomic particles. Leptons, which are collections of subatomic particles that react to lesser forces, are among the elementary particles that also comprise electrons.
Therefore the correct option is B.

find the non permissible replacement for a in the expression of 4/-9a?
Final answer:
The non-permissible replacement for 'a' in the expression '4/-9a' is '0' because it would result in division by zero, which is undefined.
Explanation:
The non-permissible replacement for a in the expression 4/-9a is the value of a that makes the denominator equal to zero, as division by zero is undefined in mathematics. To find it, we set the denominator -9a equal to zero and solve for a:
-9a = 0
a = 0 / (-9)
a = 0
Therefore, the non-permissible value for a in the expression is 0, because it would make the denominator zero and the expression undefined.

What is the the result of mixing a water molecule and an oxygen molecule together?
A.they are not attracted to each other because one is polar and one is no polar.
B. They are attracted to each other because they are both polar.
C. They are not attracted to each other because water contains an ion bond.
D. They are attracted to each other because they are both nonpolar.
Final answer:
Water is a polar molecule with a bent shape that leads to partial charges, while an oxygen molecule is nonpolar. Water and oxygen do not attract each other based on polarity. So the correct option is A.
Explanation:
The result of mixing a water molecule and an oxygen molecule can be assessed by understanding the polarity of each molecule. Water is a polar molecule due to its bent shape and the difference in electronegativity between the hydrogen and oxygen atoms, leading to partial positive and negative charges at different parts of the molecule. Since the oxygen molecule (O₂) is nonpolar and does not have a separation of charge, water and oxygen are not attracted to one another based on polarity.
Therefore, the correct answer is A. They are not attracted to each other because one is polar and one is nonpolar.

Which of the following best describes a way in which all living things organisms are similar
All living organisms share fundamental characteristics such as cellular structure, DNA as genetic material, metabolism, growth, responsiveness, reproduction, and the ability to adapt through evolution.
All living organisms, from the complexity of a human being to the simplicity of single-celled bacteria, share several fundamental characteristics that define life. Despite the immense diversity found in the biological world, these shared traits illustrate the common evolutionary history of all life on Earth.
Shared Characteristics of Living Organisms
Cellular Organization: All known living entities are composed of one or more cells, which are considered the basic units of life.Genetic Material: Every organism uses DNA to store and transmit genetic information.Metabolism and Energy Processing: Organisms take in energy and transform it to perform all life functions.Growth and Development: Organisms grow and develop according to the data encoded in their DNA.Response to Stimuli: Living things exhibit sensitivity or response to changes in their environment.Reproduction: Life replicates itself through the process of reproduction, which could be asexual or sexual.Evolution and Adaptation: Through the process of natural selection, organisms evolve adaptations to their environment, which is evidenced by the genetic homology in DNA sequences among related species.Homeostasis: They maintain internal balance, or homeostasis, despite changes in the external environment.Which of the following statements violates the cell theory? A) Mitosis produces new cells identical to the parent cell that divided to make them. B) Viruses are not considered to be living organisms, because they are smaller than a cell. C) Though humans are one organism, they are composed of about 100 trillion individual cells. D) Some scientists believe that prions, tiny proteins much smaller than a cell, that can replicate themselves, may be living organisms.

Viruses cannot reproduce without a host, they do not need to excrete waste nor breathe, but they do die and they do evolve. Scientists, however, do not consider viruses to be living things. Why?
Because living things must exhibit all characteristics of life to be considered living
Because living things must be able to reproduce on their own
Because living things must be able to excrete some form of waste
All of the above are true
Viruses are not considered living things because they do not meet all the criteria of life, such as the ability to reproduce independently and carry out metabolic processes. They depend entirely on host cells for reproduction, lacking the cellular machinery necessary for living organisms.
Explanation:Scientists do not consider viruses to be living things because they do not exhibit all the necessary characteristics of life. Viruses cannot reproduce without a host, they do not maintain homeostasis, they lack metabolic processes, and they do not grow or respond to their environment in the way living organisms do. Living things must be able to reproduce on their own, maintain a stable internal environment, carry out metabolism, and respond to their environment. Despite sharing some traits with living organisms, such as containing genetic material and the ability to evolve, viruses do not meet all the criteria needed to be considered alive.
The correct answer to the student's question is: 'Because living things must exhibit all characteristics of life to be considered living'. This encompasses the inability of viruses to reproduce on their own, the lack of metabolic processes, and the absence of other life-sustaining activities that are characteristic of living organisms.

Approximately two-thirds of the mass of a cell is water, and the water is important to maintain the cell's integrity. What would happen to a plant cell during a period of severe drought?
Answer: The plant cell would die
Explanation:
Water is one of the important component in the body of the living organism. It is used to maintain the integrity of the cell.
The cytoplasm in the cell is completely made of water and it helps in the various metabolic activities that takes place inside the cell.
The water inside cell helps in providing mobility to the cell. In the period of severe drought, the cells integrity will be disturbed and the cell would die deprived of water.
An organism had a gene sequence ATGGATACGT that underwent mutation in the noncoding region and formed ATGCGATACGT. The sequence underwent insertion mutation.will This mutation alter the protein function.
An insertion mutation in the noncoding region of a gene may not alter the protein function directly but can affect gene expression or regulation.
The student's question asks whether an insertion mutation in the noncoding region of a gene will alter the protein function. If the sequence ATGGATACGT underwent an insertion mutation and formed ATGCGATACGT, this added base is within the sequence but we cannot determine the effect on the protein function without knowing if the mutation is within the coding or noncoding region. Since the question specifies that the mutation is in the noncoding region, this mutation may not affect the protein directly. However, it's important to understand that changes in noncoding regions can sometimes affect gene expression or regulation, potentially leading to changes in the amount of protein produced or the timing of its production without altering the amino acid sequence of the protein itself.
Drag the labels to the correct locations on these images of human chromosomes
In Biology, human chromosomes are structures containing our genetic information and consist of three main regions: the centromere, the short arm (p), and the long arm (q). A standard human cell contains 23 pairs of chromosomes, totaling 46.
Explanation:The request to 'drag the labels to the correct locations on these images of human chromosomes' involves an understanding of human genetic structure. Human chromosomes consist of DNA and proteins and they carry our genetic information. A typical human cell contains 23 pairs of chromosomes, for a total of 46. These include 22 pairs of autosomes and one pair of sex chromosomes, which determine a person's sex.
Generally, each chromosome has three key regions: the centromere, the short arm (p), and the long arm (q). The centromere is what links sister chromatids (the identical copies formed during replication) together. The region above the centromere is known as the 'p' arm, while the region below is the 'q' arm.
