Answer:

1. Why are earthquakes monitored worldwide instead of in earthquake-prone areas only?

Earthquakes are monitored worldwide instead of just earthquake-prone areas since earthquakes can happen all over the world, even far away from plate boundaries.

2. How many seismographs are needed to find the epicenter of an earthquake? Why is this number significant?  

You need at least three seismographs to find the epicenter of an earthquake. The reason you need three or more seismographs is so you can see where the waves overlap to find the epicenter.

Answer:

earthquakes are monitored worldwide because we never know when they will occur, they can happen everywhere in the world even in the areas that are far away from the tectontic plates boundaries. that is why earthquakes are monitored worldwide instead of in earthquake-prone areas only.

In not less Than 100 words, explain PPLO
geniusboy [140]
PPLO stands for Pleuropneumonia-Like Organism and it means: Mycoplasma.

Pleuropneumonia means pneumonia complicated with pleurisy.

Mycoplasma means any of a group of small typically parasitic bacteria that lack cell walls and sometimes cause diseases.

(I hope this helps in anyway possible. Sorry if it's not in 100 words, I couldn't get to that number. But maybe you can put more words into the sentences and make them longer. But I do really hope this has helped you!)

<h2 /><h2>In situ hybridization</h2>

Explanation:

A)the cellular and tissue specific localization of the mRNA encoded by a particular gene

  • In situ hybridization is a technique used to locate and detect nucleic acid sequences(DNA or RNA) with respect to their protein product within nuclei
  • The principle behind in situ hybridization is that specific annealing(heat treatment process) of labelled probe to complementary sequences of target DNA or mRNA in a fixed specimen is done
  • Probe is mainly used to find the complementary sequence of the nucleic acids(DNA or RNA) or helps in localization of particular clone
  • The detection and visualization of the hybrids can be done by using cytological methods

   The Moon always shows Earth the same face.

PLANETS

A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
