All living things move.
Correct Answer
B. False
Explanation
The statement "All living things move" is not true because there are many living things that do not have the ability to move. For example, plants are living things but they are rooted to the ground and cannot move. Additionally, some animals such as sponges or corals are also living things but they are sessile and do not have the ability to move from one place to another. Therefore, the correct answer is False.
4.
All living things are made of multiple cells.
Correct Answer
B. False
Explanation
The statement "All living things are made of multiple cells" is incorrect. While most living things are made up of multiple cells, there are some exceptions. For example, certain single-celled organisms, such as bacteria and yeast, are considered living but consist of only one cell. Therefore, the correct answer is False.
5.
Some living things reproduce using only one parent.
Correct Answer
A. True
Explanation
Some living things reproduce using only one parent, a process known as asexual reproduction. This type of reproduction involves the production of offspring that are genetically identical to the parent. Examples of organisms that reproduce asexually include bacteria, fungi, and some plants and animals. In these cases, there is no need for the involvement of a second parent or the fusion of gametes. Therefore, the statement that some living things reproduce using only one parent is true.
6.
Inheritance is determined by DNA.
Correct Answer
A. True
Explanation
Inheritance is determined by DNA because DNA contains the genetic information that is passed down from parents to their offspring. DNA is made up of genes, which are the units of heredity. These genes determine various traits and characteristics of an individual, such as eye color, hair type, and susceptibility to certain diseases. During reproduction, the DNA from both parents combines to create a unique combination of genes in the offspring, resulting in inherited traits. Therefore, it can be concluded that inheritance is indeed determined by DNA.
7.
All living things obtain energy the same way.
Correct Answer
B. False
Explanation
Living things do not obtain energy in the same way. Different organisms have different methods of obtaining energy. For example, plants use photosynthesis to convert sunlight into energy, while animals consume other organisms for energy. Therefore, the statement that all living things obtain energy the same way is false.
8.
Homeostasis is a living organism's ability to maintain stable internal conditions.
Correct Answer
A. True
Explanation
Homeostasis refers to the ability of a living organism to regulate and maintain stable internal conditions, such as body temperature, pH levels, and blood sugar levels, despite changes in the external environment. This process is essential for the proper functioning of cells, tissues, and organs, ensuring that they can carry out their functions optimally. Therefore, the statement "Homeostasis is a living organism's ability to maintain stable internal conditions" is true.
9.
Living organisms stay the same over time.
Correct Answer
B. False
Explanation
Living organisms do not stay the same over time. They undergo various changes and adaptations throughout their lifespan. This is evident through processes such as growth, development, reproduction, and aging. Organisms also interact with their environment, which can lead to further changes and adaptations. Therefore, it is incorrect to say that living organisms stay the same over time.
10.
Cells are larger than molecules.
Correct Answer
A. True
Explanation
Cells are larger than molecules because cells are the basic structural and functional units of living organisms, while molecules are made up of atoms and are smaller in size. Cells contain various molecules such as proteins, nucleic acids, carbohydrates, and lipids, which work together to carry out the functions necessary for life. Molecules are the building blocks of cells, and cells are composed of multiple molecules. Therefore, cells are generally larger in size compared to individual molecules.
11.
Groups of similar cells form tissues.
Correct Answer
A. True
Explanation
Groups of similar cells that perform a specific function come together to form tissues. This is a fundamental concept in biology, where cells with similar structures and functions combine to create different types of tissues such as muscle tissue, nervous tissue, and epithelial tissue. These tissues then work together to form organs and organ systems, allowing the body to carry out various functions efficiently. Therefore, the statement "Groups of similar cells form tissues" is correct.
12.
An ecosystem is the largest level of biological organization.
Correct Answer
B. False
Explanation
An ecosystem is not the largest level of biological organization. The correct answer is False. The correct explanation is that the biosphere is the largest level of biological organization. The biosphere includes all of the Earth's ecosystems, as well as the atmosphere, hydrosphere, and lithosphere. It encompasses all living organisms and their interactions with the environment on a global scale.
