How fast do seismec waves caused by earthquakes travel​

Biology
1 answer:
Ipatiy [6.2K]3 years ago
4 0

Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer. The propagation velocity of the waves depends on density and elasticity of the medium.Velocity tends to increase with depth and ranges from approximately 2 to 8 km/s in the Earth's crust, up to 13 km/s in the deep mantle.

Nikitich [7]

Explanation:

Earth's Orbit = 2*pi*R = 942,000,000 kilometers.

Distance/Time = 942,000,000 km / 8766 hr = 107,000 km/hr = 30 km/sec.

Complete the graphic organizer to summarize exceptions to Mendels principles
Butoxors [25]

Answer:

<em>Exceptions to Mendel's principles: </em>

Does exceptions mean that Mendel was "wrong"? The answer is "NO". It means that we know more today about diseases, genes, and heredity than compared to what he expalined 150 years ago. Here I have summerized the exceptions with examples:

<em>Incomplete dominance</em>: When an organism is heterozygous for a trait and both genes are expressed but not completely.

<em>Example</em><em>:</em> SnapDragon Flowers

<em>Codominance</em>: When 2 different alleles are present and both alleles are expressed.

<em>Example</em>: Black Feathers + Whites feathers --> Black and white speckled feathers

<em>Multiple alleles</em>: Three or more alternative forms of a gene (alleles) that can occupy the same locus.

Example: Bloodtype

<em>Polygenic traits</em>: more than one gene controls a particular phenotype

Example: human height, Hair color, weight, and eye, hair and skin color.

Name the three types of population distribution, describe each, and explain the conditions that govern each.
tankabanditka [31]

Answer: Population distributions may be described as <em>random, uniform</em><em> or </em><em>clustered.</em>

Explanation:

In a specified region, a population comprises any  number of members of the same species. Populations are described by sizes- the number of individuals; densities-  individuals in a set space (per unit area); and distribution- the dispersal or non dispersal of individuals (spread out or clumped). Population distributions may be described in three ways:

  • Random: the distribution pattern is haphazard, with no regular spacing; individuals grow independently of each other without competing and resources are consistent. <em>E.g. dandelion seed dispersal by wind </em>

  • Uniform:  individuals are evenly spaced in a predictable pattern; there may be some interaction and ideally, spaces between them  are maximized in order to ensure access to limited nutrients and resources.<em> E.g.  human farming- cornfields, orchards; allelopathy in plants like purple sage, which secretes chemicals to prevent the growth of other plants nearby</em>

  • Clumped: there is less distance between neighboring organisms and these individuals cluster together. This pattern is most common in environments where resources are scarce, or the species is dependent on social interactions.<em> E.g. lions are highly social and hunt in prides in the wild</em>

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:

Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface

b) Replacement of a polar amino acid with another polar amino acid at the protein's surface

c) Replacement of a polar amino acid with another polar amino acid in the protein's interior

d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
