Answer
:proteins
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.
Explanation:
Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Answer:
Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses

Read each of the answers below carefully: Which statement best describes the cell cycle? a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase. b. Cells grow and develop during the mitotic phase. Cells reproduce during interphase. c. The nucleus of the cell divides during interphase. The cytoplasm of a cell divides during the mitotic phase. d. The nucleus of the cell divides during the mitotic phase. The cytoplasm of a cell divides during interphase.
Answer:
a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
The statement best describes the cell cycle - a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

The different themes of biology include emergent properties, the cell, heritable information, structure and function, interaction with the environment, regulation, unity and diversity, evolution, scientific inquiry, and science, technology, and society.
What are the different themes of Biology?A theme is an idea or a topic which is expanded in a discourse, discussion, etc. in literature, music, art, or any subject, discipline, etc.
The major themes of biology include:
Emergent Properties: These are critical attributes of biological systems, as the understanding of the individual parts alone is insufficient to understand or to predict the system behavior.
The Cell: It is the basic unit of life. Unit is capable of independent existence. Cells are studied to understand the functioning of organisms.
Heritable Information: This includes the transfer of information and genes from parents to offspring. This is included under genetics.
Structure/Function: This includes the structure and function study of living organisms.
Interaction with the Environment: This theme of biology includes the interaction of various living and non-living things with the environment.
Regulation: This theme involves the regulation of the biospheres of the planet.
Unity and Diversity
Evolution: This theme involves the evolution of different organisms over time which took place on this planet.

Describe the interactions between organisms within an ecosystem. Give an example of a specific relationship that organisms may have, and how this relationship affects the ecosystem.
Answer:
Predation: One Wins, One Loses. Predation includes any interaction between two species in which one species benefits by obtaining resources from and to the detriment of the other.
Competition: The Double Negative. Competition exists when multiple organisms vie for the same, limiting resource.
Mutualism: Everyone Wins. Mutualism describes an interaction that benefits both species.
Commensalism: A Positive/Zero Interaction. An interaction where one species benefits and the other remains unaffected is known as commensalism.
Amensalism: A Negative/Zero Interaction. Amensalism describes an interaction in which the presence of one species has a negative effect on another, but the first species is unaffected.

In which situation would water enter a cell through omosis?
Answer:
Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.
