Using the s-p timing method, epicenters can be located using seismograms from a minimum of ______ recording stations.

1 answer:

7 0

The SP timing method is a technique, which is useful for finding the epicenter of the earthquake. The Seismograph at a particular station shows the S and the P waves. The difference between the S and the P waves can be used to determine the distance, which waves have travelled in order to reach the seismic station.

The distance obtained is the distance of the epicenter from that seismic station, in order to determine the epicenter the circle is drawn in the map keeping the seismic center at the center. Same process is done by three or more seismic centers. The point, where the circle drawn by three or more seismic centers meet is considered as the epicenter.

Hence, the correct answer is Three.

Explain how the result of meiosis and cytokinesis affects inherited traits

Anna71 [15]

Answer:

Meiosis is a type of cell division in which a single cell is divided into four daughter cells having half number of chromosome while cytokinesis is the division of cytoplasm.

Meiosis occurs only in sex cells which are responsible for the formation of new organism. Traits are transferred from parents to the offspring through the process of sexual reproduction. In sexual reproduction, sex cells i. e. sperm cells of male fuse with egg cell of female forming a zygote which turns into a new organism and traits are transferred from one generation to another.

Answer:

The student claim is incorrect

Explanation:

Uncontrollable cell division leads to formation of tumours and cancers if cells were to lose contact inhibition and migrate to other parts of the body.

What term refers to how fast blood traveled from its source? _________ refers to how fast blood traveled from its source to wher

muminat

Answer:

Impact.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

In Science, the study of blood is generally referred to as serology.

Impact refers to how fast blood traveled from its source to where it landed.

This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;

I. Displacement.

II. Retraction.

III. Contact and collapse.

IV. Dispersion.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

Define newton's first law in your own words.

Setler79 [48]

All object in motion will stay in motion unless acted upon by an external force. This means whenever something is moving then something else has to stop it. If an object is not moving then it will stay not moving until something forces it to move.
