Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
Answer:
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem.
Explanation:
Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.

gladu [14]
Answer:
species is a group of organisms of common ancestry able to reproduce only among. reproduction is Formation of new cells or a new individual. adaptation is A changing to fit new conditions. niche is ecology) the status of an organism within its environment and community (affecting its survival as a species). camouflage is camouflage. mimicry is Gaining protection by looking and acting like a different species. migration is Form of relocation diffusion involving permanent move to a new location. hibernation is A state of extremely low metabolism and respiration, accompanied by lower-than-normal body temperatures. predator is An animal that hunts other animals for food. prey is Animal hunted or caught for food. habitat is Place where an organism lives. organism is any living thing made up of one or more cells. invasive species is plants and animals that have migrated to places where they are not native. last non native species is not from an area, usually harmful.
Explanation:
Answer:
It is strong enough to bind different tissue types together, yet soft enough to provide flexibility and cushioning. It exhibits interlacing, loosely organized fibers, abundant blood vessels, and significant empty space filled with interstitial fluid.
