all derived traits are synapomorphies. all homoplasies are homologous traits. these statements are not true about systematics.
What are homologous traits?Characteristics that can be passed down from parent to child are known as traits. In biology, the term "homologous" refers to a similarity in internal or chromosomal structures.
Therefore, homologous qualities are common characteristics among various but related species.
Examples of homologous structures include bat wings, mouse legs, human finger bones, crocodile legs, and other four-legged vertebrate legs. Another example would be the altered leaves of carnivorous plants, cacti, and poinsettias, as well as the skeletons of whales and hummingbirds.
Homologous chromosomal structures mean chromosomes that carry the same genetic material, even if the expression of the genetic material differs.

If you change the difference in lag times of P and S waves from 00:01:50 to 00:04:00,
how does that change the distance of the earthquake to the seismic station?
The farther a seismic station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
As the P and S waves journey out from an earthquake the P waves get regularly farther ahead of the S waves. therefore, the farther a seismic station is from the earthquake epicenter the more may be the distinction in time of arrival between the P and S wave.
The distinctive waves every travel at different speeds and therefore arrive at a seismic station at specific times. P waves tour the fastest, so they arrive first. S waves, which tour at approximately half the rate of P waves, arrive later.
P and S waves may be used to discover the epicenter of an earthquake. Since P waves are faster than S waves, the larger the appearance time distinction between the 2 waves is, the farther that location is from the epicenter.

among major extant lineages, horizontal gene transfer (hgt) rarely occurs; in fact, most organisms have evolved defenses against such intrusions. why might hgt have been more common among early life-forms than in later ones?
HGT now rarely occurs but was more common in early life forms because earlier the organisms had less complex body organization and thus were less disrupted by HGT.
Body organization is the arrangement of body cells and tissues and their complexity. The simplest form of body organization is unicellular. Next is multicellular, then organs, organ system and then finally a complete complex living organism.
HGT is Horizontal Gene Transfer. It is the form of gene transfer other than the transfer of genes from parents to offspring. Thus form of gene transfer occurs through recombination or insertion. It is common in unicellular and small multicellular organisms.

Describe how the nervous system coordinates the response of the skin to cold weather.
The sympathetic nervous system is stimulated when the skin's cold receptors are stimulated, resulting in cold thermal sensations. In the skin, arms, and legs, sympathetic stimulation causes vasoconstriction.
In a variety of physiological ways, the nervous system coordinates the skin's response to cold weather.
The following are the physiological changes that occur in response to cold temperatures:
Cold weather triggers the activation of cold receptors on the skin's surface.The sympathetic nervous system is stimulated and cold thermal sensations are brought on by these receptor stimulations.This stimulation causes vasoconstriction in the skin, arms, and legs, which reduces blood flow and makes the skin thinner, which makes superficial tissues more efficient at insulating heat.Below the thermoneutral zone, metabolic heat generated by shivering is stimulated.
