Sorry that you can’t really read that. The last work is surface wave. Please help

Biology

NikAS [45]3 years ago

Explanation:

Earthquakes occur when elastic energy is accumulated slowly within the Earth's crust as a result of plate motions and then released suddenly at fractures in the crust called faults. The released energy travels in the form of waves called seismic waves. They always start at the focus. (A focus is where an earthquakes starting place.) The the power would start to travel and hit the  epicenter, an epicenter is the point on land directly above the focus, soon on the surface. There are three types of earthquakes, the Primary, Secondary, and surface waves. Primary waves cause the rocks they pass through to change in volume. These waves are the fastest traveling seismic waves and can travel through solids, liquids, and gases. Also called P wave See Note at earthquake. Secondary waves start at the same time as primary waves. Secondary waves travel through Earth's interior at about half the speed of primary waves. Secondary waves are also called S waves. And Surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities.

PLSSS HELP <br> Do you think an international orbiting space station is a good idea? Why or why not?
maksim [4K]

Answer:

Yes it is (we already have one)

An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.

No it isn't

An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.

How is the cell structure related to its function in your body
Nastasia [14]

<span>A cell with a large surface area or with microvilli (which increase surface area) are specialized for absorption. Many cells have different protein markers on their surface to accept certain specific hormones and allow them into the cell, like muscle cells reacting to adrenaline. Muscle cells are long and able to contract, allowing for overall muscle contraction and body movement. </span>

<span>I guess the hormone part I mentioned applies to chemicals; endocrine cells produce hormones that other cells would not. </span>

<span>For organelles, muscle cells don't have many of the organelles that other cells do because of their very specialized functions. </span>

<span>I hope this helps, it would literally take volumes of text books to answer this question completely.</span>

If you were making a product of artificial "Grow-Lites" for plants, what color light should
UNO [17]

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).

Many prokaryotes reproduce through binary fission. The circular DNA is
Soloha48 [4]

Answer:

D

Explanation:

Mitosis is a form of reproduction in simple living organisms. The outcome of mitosis is two identical daughter cells, and it follows the process described in the prompt. It doesn't require genetic material from another organism, so it's asexual reproduction.
