The clownfish (amphiprion ocellaris), which belongs to the phylum Chordata and class Mammalia, is most closely related to humans (Homo sapiens).

Clownfish and anemonefish are both names for fish that belong to the subfamily Amphiprioninae of the family Pomacentridae. The thirty species of clownfish that are currently known fall into two genera: Amphiprion and Premnas. In the wild, they all form symbiotic mutualisms with sea anemones. Anemonefish come in a range of colours overall, including yellow, orange, reddish, and even blackish. Many also have white stripes or patches.

Conventional wisdom holds that complex structures evolve from simpler ones, step-by-step, through a gradual evolutionary process, with Darwinian natural selection favoring intermediate forms along the way.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

squamous keratinized epithelium that is stratified.

The upper respiratory tract is lined with this kind of epithelium, which often includes many cilia.

Pseudostratified epithelium has cilia, which are tiny hair-like extensions, and goblet cells, which are single-cellular glands that release mucus.

To convey bacteria, viruses, epithelial debris, or other harmful substances up or out of the airway, the cilia beat in unison over the epithelium. The epithelium's goblet cells make mucus, which helps in gathering the debris for ejection out from the airway. Cuboidal epithelial cells primarily perform three tasks: absorption, secretion, and protection. Specialized structures protrude from a few cuboidal epithelial cells.

Catecholamines and serotonin, the two types of chemical signals in the body that help maintain homeostasis are hormones and neurotransmitters.

The maintenance of homeostasis in the human body is greatly aided by neurotransmitters like serotonin and catecholamines. The major focus of research on these neurotransmitters has been on how they affect blood flow throughout the body and the "fight or flight" response by sending messages across chemical synapses.

In homeostasis, the body's organs can cooperate to keep blood glucose levels stable thanks to the chemical signal insulin, which is produced by the pancreas, liver, and muscles. This makes it possible for the body's other organs, including the heart and brain, to keep homeostasis.

The sympathetic nervous system uses norepinephrine as a neurotransmitter. The hypothalamus is where these molecules keep energy homeostasis in check. This homeostatic mechanism, which regulates energy input-output and food intake, is kept in check by the hypothalamus.

Solute and water from the blood are pushed through the slits and pores of the glomerulus into Bowman's capsule.

The glomerulus is a network of tiny blood vessels located within Bowman's capsule in the renal system. It serves as a filter for the blood, allowing only specific substances to pass through its slits and pores into Bowman's capsule. This process, known as filtration, pushes solute and water from the blood into Bowman's capsule, while large proteins, wastes, and other unwanted substances are prevented from passing through and are instead returned to the bloodstream. Glucose is also a type of solute, and so it would be pushed through the slits and pores of the glomerulus along with other solutes. The filtrate within Bowman's capsule then undergoes further processing in the renal system to remove waste and excess fluid, and to conserve important nutrients and electrolytes.

Lac operon is lactose operon which is required for transport and metabolism of lactose in the bacteria.

Lac operon is a lactose operon which is required for the transport and metabolism of lactose sugar in the Escherichia coli cell. The lac operon has many genes including the repressor gene, operator region, promoter  gene, and structural genes.

Lactose is an inducer molecule of the operon. If lactose is absent then the repressor gene encodes repressor protein in the cell which binds to the operator region in the gene and prevent RNA Polymerase to bind to the promoter sequence and hence, transcription of the structural genes is inhibited in the cell. Hence, the lac operon is turned off in the absence of sugar.
