A biologist discovers an alga that is marine, multicellular, and lives at a depth reached only by blue light. This alga is most likely a type of red algae
<h3>What is
red algae?</h3>
Red algae, often known as Rhodophyta (from the Greek words v (rhódon) "rose" and phutón "plant"), are one of the oldest subgroups of eukaryotic algae. Additionally, the Rhodophyta is one of the largest phyla of algae, with over 7,000 species now recognized and continuous taxonomic revisions. The Florideophyceae (class) contains 6,793 species, the bulk of which are multicellular marine algae, including numerous well-known seaweeds. Red algae are prevalent in coastal environments but are scarce in freshwater environments.
Freshwater ecosystems contain 5% of red algae species, with warmer regions having higher amounts. There are no terrestrial species, with the exception of two species of asexual Cyanidiophyceae species that live in coastal caves. This lack of terrestrial species may be the result of an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and most of its evolutionary plasticity.

Answer:
Action potentials.
Explanation:
Receptors are present in the body surface that helps in the detection of the changing inside and outside environment of the body. Different receptors are sensory receptors, baroreceptors and chemoreceptors.
Action potential is the transmission of nerve impulse that occur due to the change in the electric potential of the cell. The information from the baroreceptors occurs by the propagation of the action potential.
Thus, the correct answer is option (c).
Answer:
An animal's environment consists of many different things. The climate, the kinds of food plants that grow in it, other animals that may be predators or competitors- the animal must learn to adapt to each of these factors in order to survive.
Qualities that have nothing to do with genetics are dependent on an organism's environment and the organism's genetics do not play a role in determining them. For example, if a person's finger is cut off, this is a trait that is independent of genetics. The loss of a finger will not be inherited into the organism's offspring.
Traits that are dependent on genetics are those such as eye color and height.
