Cetacea is divided into two sub-orders: Mysticeti (baleen whales) and Odontoceti (toothed whales). The primary structures that differentiate these sub-orders are the presence of baleen plates in Mysticeti for filter feeding, while Odontoceti possess teeth for hunting. Additionally, Mysticeti tend to be larger and have a more streamlined body shape, whereas Odontoceti exhibit a range of sizes and often have more complex social structures and behaviors.

How is order cetacea organized?
Order Cetacea is organized into two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales). Mysticeti includes whales that filter feed using baleen plates, while Odontoceti includes whales with teeth for hunting. Each suborder further divides into families, genera, and species based on specific anatomical and genetic characteristics.
Genes are found on these cell structures that become visible when cells divide?
Genes are found on chromosomes, which are thread-like structures composed of DNA and proteins. They become visible when cells divide through a process called mitosis. During mitosis, chromosomes condense and are separated into two identical sets to be distributed to daughter cells.
What two structures contain DNA?
The two-rod structures that contain the cell's DNA is the chromosome.
What are branching fibers?
Branching fibers refer to fibers or structures that divide into two or more smaller branches or strands. In biology, neurons in the brain often have branching fibers that help transmit electrical signals to other cells.

How is order cetacea organised?
Order Cetacea is divided into two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales). Mysticeti includes whales that feed through baleen plates, while Odontoceti includes whales with teeth for hunting. These suborders are further divided into families, genera, and species based on various characteristics such as size, feeding habits, and habitat.
What structures divide cetacean into two suborders?
Cetaceans are divided into two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales) based on their feeding structures. Mysticeti possess baleen plates that filter food from the water, while Odontoceti have teeth that allow them to grasp and consume larger prey. These anatomical differences reflect their distinct feeding strategies and ecological roles in marine environments.
What are classifications of the cetacea order?
The cetacea order is classified into two suborders: Odontoceti (toothed whales) and Mysticeti (baleen whales). Odontoceti includes dolphins, porpoises, and sperm whales, which have teeth for hunting. Mysticeti includes species like humpback and blue whales, which have baleen plates to filter feed.

What is the scientific classification of octopus?
Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Superorder: Octopodiformes Order: Octopoda There are two suborders, Cirrina and Incirrina, and within those two suborders there are many families and then species.
Which structures are contained within the petrous portion of the temporal bone?
The structures that are found deep within the petrous part of the temporal bone are related to the inner ear. Most scientists divide the structures into two parts the mastoid part and the petromastoid part.
What are two structures that belong to the respitory system?
Two structures that belong to the respiratory system are the trachea (windpipe) and the bronchial tubes. The trachea carries air from the throat to the lungs, while the bronchial tubes divide in the lungs to deliver air to each lung's air sacs.
