LAB| LAB QUESTIONS WITH 100% CORRECT
ANSWERS PART 1: SECTIONS 1 AND 2| UPDATED
2024
These are the questions for the labs from the course material. Please answer the questions, but also for
each answer choice, explain why the choice is correct or incorrect. For example, if the answer is B,
please explain why B is correct and why choices A, C, and D, etc., are incorrect, for each question. Also,
for the images, label all parts of the image, if they are unlabeled. For the matching questions, explain all
choices, even if they were not used to answer one of the questions. This will give you extra practice
with the material, which will help with synthesis and retention. An example of this process is below.
Atoms combine to form molecules, for example, water, glucose, and DNA. In what level of structural
organization does this take place?
a. Molecules This is not correct because it is not a name of a level of organization. The name of
the lowest level of organization is chemical.
b. System This is not the correct answer because systems are four levels of organization higher
than chemical. (chemical, cell, tissue, organ, system, organism)
c. Tissues This is not the correct answer because tissues are two levels of organization higher than
chemical. (chemical, cell, tissue, organ, system, organism)
d. Chemical This is the correct answer because chemical is the lowest level of structural
organization.
Section 1 Labs
1. Atoms combine to form molecules, for example, water, glucose, and DNA. In what level of
structural organization does this take place?
a. Molecules are the correct answer Chemical bonds allow atoms to unite to create
molecules. When two or more atoms interact with one another through or hydrogen
interactions, whether they are from the same element or different ones, molecules are
created. In the case of water, glucose, and DNA, atoms from various elements come
together to form the molecules of water (H2O), glucose (C6H12O6), and DNA (consisting
of nucleotides).
b. System: A group of interconnected, interacting pieces is referred to as a "system" when
they work as a unit. Despite the fact that atoms and molecules might be components of
a system, the process by which atoms combine to form molecules does not necessarily
take place at the level of a system. Hence not correct
c. Tissues not correct because in multicellular animals, tissues are made up of specialized
cells that collaborate to carry out particular tasks. Although molecules are found in both
cells and tissues, the formation of molecules takes place at a lower degree of
organization than that of tissues.
d. Chemical the word "chemical" is too general to adequately characterize the level of
structural organization where atoms join to create molecules, hence this option is
inaccurate. All facets of matter and its interactions, including atoms, molecules,
,compounds, reactions, and more, are studied in chemistry. There is no particular level of
structural organization involved.
,2. Organelles are usually associated with which level of structural organization?
a. Tissues not correct Cellular communities that make up tissues collaborate to carry out
particular tasks. Although organelles are found in cells, they are not explicitly linked to
the degree of organization that exists in tissues.
b. Cellular is the correct response Organelles are specialized cell structures that carry out
particular tasks essential for the survival and general health of the cell. The nucleus,
mitochondria, endoplasmic reticulum, Golgi apparatus, and chloroplasts (in plant cells)
are a few examples of organelles.
c. Organ not correct because Organs are intricate structures made of various tissues that
collaborate to carry out particular duties in multicellular animals. Organelles are seen in
cells; however they are not always connected to the degree of organization at which
organs exist.
d. System is not correct because Systems in multicellular organisms are groups of organs
that interact or are dependent upon one another to carry out particular tasks. The
degree of organization at which systems are present is not specifically related to
organelles.
3. Groups of form , a more complex structural organization in the human body.
a. Organs, cells are the correct answer organ systems, organs, tissues, cells. The order
below indicates an arrangement from complex to the simplest level of organizations in a
human being. Generally, a group of cells forms a tissue.
b. Systems, tissues is not the right answer because systems refer to a higher level of
organization that consists of multiple organs working together to carry out a particular
function. Tissues are the next level down in structural organization, composed of groups
of cells with similar structures and functions.
c. Cells, tissues is not the correct answer because cells are the basic building blocks of life
and are organized into tissues, not the other way around.
d. Tissues, cells are not the right answer because tissues are made up of cells, and they are
organized into organs, which are the level of organization specified in the question.
4. A(n) is a structure composed of two or more different types of tissue.
a. Organ correct answer
An organ is a structure composed of two or more different types of tissue that work
together to perform specific functions within an organism. Organs are higher-level
structures in the hierarchy of biological organization, consisting of different tissues that
are organized and integrated to carry out specialized tasks
b. Cell not correct
A cell is the basic structural and functional unit of all living organisms. It is the smallest
unit of life and is not composed of different types of tissues.
c. Tissue incorrect
, Tissue refers to a group of similar cells that work together to perform a specific function. While tissues
are made up of cells, they are not composed of different types of tissues.
d. Molecule incorrect
A molecule is a group of atoms bonded together. It is the smallest unit of a chemical
compound and is not composed of different types of tissues.
5. Related working for a common function constitute a .
a. tissues, system incorrect answer
While tissues do make up organs, they do not constitute a system. Systems are formed
by the collaboration of multiple organs.
b. cells, organ incorrect answer
While cells are the basic building blocks of tissues, they do not constitute an organ.
Organs are composed of different types of tissues.
c. tissues, cell incorrect answer
This option incorrectly suggests that tissues are composed of cells, which is the reverse
relationship. Tissues are made up of cells, not the other way around
d. organs, system is correct
In biology, organs are composed of different types of tissues that work together to
perform specific functions. A system, on the other hand, is a group of organs that work
together to carry out a common function in the body.
6. Organ systems work together within the .
a. membranes While membranes are a part of the body and play essential roles in various
physiological processes, they do not encompass all organ systems. Organ systems are
composed of multiple organs working together, and membranes are not a broad enough
term to encompass all organ systems.
b. tissues tissues: Tissues are groups of cells that work together to perform a specific
function. While tissues are a part of organ systems, they alone do not encompass all
organ systems. Organ systems are composed of multiple tissues and organs working
together.
c. cells incorrect answer Cells are the basic building blocks of living organisms, and while
they are fundamental to the functioning of the body, they do not encompass all organ
systems. Organ systems consist of multiple tissues, organs, and cells working together.
d. Body is the correct answer as it accurately represents that organ systems work together
within the body as a whole.
7. What are the main types of cells? Select two answers.
