Regulation
This is when a species maintains homeostasis and controls gene expression and regulations of the internal environment to maintain a constant state
What is Regulation?
Cnidarians (jellyfish, sea anemones, etc.,) use this in order to detect and respond to stimuli from all directions
What are movements that are coordinated by a non-centralized nerve net that is associated with sensory structures distributed around the body?
In lancelets the pharynx and pharyngeal slits play a minor role in this
What is gas exchange, which occurs mainly across the external body surface?
In vertebrates, the small intestine with the finger-like projections called villi that do this
What is absorb nutrients released by the digestion of food?
A change or the process of change by which an organism or species becomes better suited to its environment, is different from regulation, and is often confused with it.
What is Adaptation?
Lophotrochozoans develop this in order to assist feeding, while others go through a distinctive stage called the trochophore larva
What is a lophophore, also know as, a crown of ciliated tentacles?
The earliest ‘’ears’’ were organs for maintaining this
What is balance, a function still performed by the ears of humans and other living vertebrates?
These animals are endothermic and most have a high metabolic rate.
What are Mammals?
An example of regulation, the ability to keep the optimal bode temperature, even when the temperature in the surroundings is different
What is Thermoregulation?
Flatworms have no organs specialized for gas exchange, so they have this in order to maintain osmotic balance with their surroundings
What is relatively simple excretory apparatus?
A sharks continual swimming ensures that this happens
What is water flows into the shark’s mouth and out through the gills, where gas exchange occurs?
In development tetrapods do not form gills, they instead focus more on developing these
What are ears, glands, and other structures helpful for regulating their environment?
Maximizing metabolic rate requires this
What is the efficient uptake of energy and raw materials, such as nutrients and oxygen, as well as the effective disposal of waste products?
This animal uses its thin finger-like structures to increase the surface area of its body, aiding in respiration and helping it to float on the seas surface
What is a blue dragon?
Amphibians require this
What are wet habitats because they rely heavily on their moist skin for gas exchange?
These animals are endothermic, and capable of maintaining body temperature through metabolic activity.
What are birds?
This occurs in chloroplasts, which have a flattened and interconnected set of internal membranes called thylakoid membranes.
What is photosynthesis?
A sponge consists of this
What is 2 layers of cells separated by a gelatinous region called mesohyl?
These animals are described as cold blooded because they do not use their metabolism extensively to control their body temperature.
What are reptiles?
Vertebrates became better than chordates at this
What is capturing food and avoiding being eaten?
