Homeostasis means
-
Change over long periods of time.
-
Keeping things the same.
-
rapid change.
-
The same thing as evolution.
Correct Answer
A. Keeping things the same.Explanation
Homeostasis refers to the ability of an organism or system to maintain internal stability and balance in the face of external changes. It involves various physiological processes that work together to regulate and keep the internal environment constant, such as body temperature, blood pressure, and pH levels. Therefore, the correct answer is "keeping things the same," as homeostasis aims to maintain a stable and constant internal state despite external fluctuations.Rate this question:

Which of the following is not necessarily a characteristic of living things?
-
Homeostasis
-
Metabolism
-
complexity
-
reproduction
Correct Answer
A. complexityExplanation
Complexity is not necessarily a characteristic of living things because there are many simple organisms that are considered living, such as bacteria. Complexity refers to the level of organization and intricacy of an organism's structure and functions, but it is not a requirement for something to be classified as living.Rate this question:

The smallest units that can carry on all the functions of life are called
-
Molecules.
-
cells.
-
Organelles.
-
Species.
Correct Answer
A. cells.Explanation
Cells are the smallest units that can carry out all the functions of life. They are the basic building blocks of all living organisms and are capable of performing essential processes such as metabolism, growth, reproduction, and response to stimuli. Cells contain various organelles that work together to maintain the cell's functions and ensure its survival. Molecules are smaller components of cells and organelles, while species refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, cells are the correct answer as they are the fundamental units of life.Rate this question:

Living things
-
Need energy for life processes.
-
Have the ability to reproduce.
-
Are composed of cells.
-
All of the above
Correct Answer
A. All of the aboveExplanation
The statement "All of the above" is the correct answer because it encompasses all the given options. Living things require energy for life processes, they have the ability to reproduce, and they are composed of cells. This answer choice includes all three statements, making it the most comprehensive and accurate option.Rate this question:
-
- 6.
All organisms are composed of
-
Diatoms.
-
cellulose.
-
Cells.
-
None of the answers
Correct Answer
A. Cells.Explanation
The correct answer is "cells." This is because cells are the basic structural and functional units of all living organisms. They are responsible for carrying out essential biological processes and are the building blocks of life. Without cells, organisms cannot exist or function properly. Diatoms and cellulose are specific components or structures found within cells, but not all organisms are composed of them. Therefore, the most accurate and comprehensive answer is "cells."Rate this question:
-
- 7.
All living things maintain a balance within their cells and the environment through the process of
-
Growth.
-
Development.
-
Homeostasis.
-
Evolution.
Correct Answer
A. Homeostasis.Explanation
Living things maintain a balance within their cells and the environment through the process of homeostasis. Homeostasis is the ability of an organism to regulate its internal environment, such as temperature, pH, and nutrient levels, to maintain a stable and optimal condition for survival. This process involves various physiological mechanisms that allow organisms to respond and adapt to changes in their external environment, ensuring their overall well-being and functionality. Growth and development are important processes in living organisms, but they do not specifically involve maintaining a balance within the cells and the environment. Evolution, on the other hand, refers to the gradual change in species over time, which is not directly related to maintaining internal balance.Rate this question:

Which of the following is a characteristic of all living things?
-
Movement
-
Photosynthesis
-
Respiration
-
Cellular organization
Correct Answer
A. Cellular organizationExplanation
Cellular organization is a characteristic of all living things because it refers to the structural arrangement of cells in an organism. All living organisms are composed of one or more cells, which are the basic units of life. These cells are organized in a specific way to carry out various functions necessary for life, such as growth, reproduction, and response to stimuli. Without cellular organization, living organisms would not be able to maintain their structure and function properly.Rate this question:

This is the process of a population changing over generations of time.
-
Evolve
-
Metabolism
-
Homeostasis
-
Sexual reproduction
-
Asexual reproduction
-
DNA
Correct Answer
A. EvolveExplanation
Evolve refers to the process of a population changing over generations of time. It involves the gradual development and adaptation of species through genetic variations and natural selection. This process allows organisms to better survive and reproduce in their environment, leading to the emergence of new species and the extinction of others. Evolution is driven by factors such as genetic mutations, environmental changes, and competition for resources.Rate this question:

-
Homeostasis
-
Metabolism
-
Sexual reproduction
-
Asexual reproduction
-
DNA
Correct Answer
A. MetabolismExplanation
Metabolism refers to the sum of all chemical reactions that take place within an organism, including both anabolic reactions that build complex molecules and catabolic reactions that break down molecules. It is responsible for the conversion of food into energy, the synthesis of molecules necessary for growth and repair, and the elimination of waste products. Metabolism is essential for maintaining homeostasis and enabling an organism to evolve and adapt to its environment.Rate this question:

This is the process by which two cells from different parents unite to produce the first cells of a new organism.
-
Evolve
-
Homeostasis
-
Metabolism
-
Sexual reproduction
-
Asexual reproduction
-
DNA
Correct Answer
A. Sexual reproductionExplanation
Sexual reproduction is the correct answer because it involves the union of two cells from different parents to produce the first cells of a new organism. This process leads to genetic diversity and variation in offspring, as genetic material from both parents is combined. In sexual reproduction, specialized reproductive cells, such as sperm and eggs, are involved in the process of fertilization, resulting in the creation of a zygote. This zygote then develops into a new organism with a unique combination of genetic traits inherited from both parents.Rate this question:

This is the process by which a single parent reproduces by itself.
-
Evolve
-
Homeostasis
-
Metabolism
-
Sexual reproduction
-
Asexual reproduction
-
DNA
Correct Answer
A. Asexual reproductionExplanation
Asexual reproduction is the process by which a single parent reproduces by itself. This means that offspring are produced without the involvement of another individual. In asexual reproduction, the parent organism can produce genetically identical copies of itself through methods such as binary fission, budding, or fragmentation. This allows for rapid reproduction and colonization of new areas. Asexual reproduction does not involve the exchange of genetic material, so the offspring are genetically identical or very similar to the parent.Rate this question:

-
Asexual reproduction
-
DNA
Correct Answer
A. DNAExplanation
DNA is the genetic material that carries the instructions for making proteins from one generation to the next. It contains the information necessary for the development, functioning, and reproduction of living organisms. DNA is composed of nucleotides, which are arranged in a specific sequence that determines the order of amino acids in proteins. Through processes such as transcription and translation, the instructions encoded in DNA are used to produce proteins, which are essential for the structure and function of cells and organisms. DNA is inherited from parents to offspring during sexual reproduction, ensuring the transfer of genetic information from one generation to the next.Rate this question:
