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.

The highlighted structure is called ___ and it is proportionally _in human compared to the similar structure in the sheep brain.
The highlighted structure is called pineal gland and it is proportionally smaller in humans compared to the similar structure in the sheep brain.
Sheeps have a small pineal gland in their elongated brain compared to that of rounded human brain's larger pineal gland. The pineal gland, often referred to as the conarium or epiphysis cerebri, is a small endocrine gland that is found in the brains of the majority of vertebrates. The pineal gland produces melatonin, a hormone derived from serotonin that controls sleep patterns in both seasonal and circadian cycles. The name of the gland comes from the way it resembles a pinecone. The epithalamus, which is at the center of the brain and situated between the two hemispheres, contains a groove where the two sides of the thalamus meet. This groove houses the pineal gland. The pineal gland is one of the circumventricular neuroendocrine secretory organs with the greatest blood solute permeability.
The majority of animals have pineal glands. The two photosensory organs found on the top of modern lampreys' heads were probably present in the vertebrate ancestor that all vertebrates share today. According to the skulls of numerous extinct Devonian fish, which have two parietal foramina, parietal eyes were once bilateral. The parietal eye and pineal gland of living tetrapods are most likely derived from the left and right parts of this organ.

What is sexual reproduction?
A gamete with a single set of chromosomes joins with another gamete to create a zygote, which then grows into an organism made up of cells with two sets of chromosomes. Sexual reproduction is a type of reproduction that requires a complex life cycle. Mixing the genetic material from two persons of different sorts to create new living things (sexes). In the majority of higher creatures, the male sex generates a small, mobile gamete that travels to the larger, stationary gamete generated by the female to fuse with it (female).
What is asexual reproduction?Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes are not altered. The whole gene pool of their single parent is inherited by the offspring that are produced through asexual reproduction from either unicellular or multicellular organisms.

By dividing the total number of copies of each allele at that particular genetic locus in the population by the number of times the allele of interest is observed in a population, an allele frequency can be calculated. The frequency of alleles can be expressed as a percentage, a decimal, or a fraction. Allele frequencies are a measure of genetic diversity in a population.
