A lunar eclipse happens when the Moon passes directly behind the Earth and into its shadow. This can only happen when the Sun, Earth, and Moon are aligned. Because of this, a lunar eclipse can only happen on the night of a full moon.
The moon gives off a reddish appearance during this time because the only light reaching the moon and reflected off of its surface is the light refracted by the Earth's atmosphere (the same reason a sunrise/sunset appears reddish).
A totally eclipsed full moon is also known as a Blood Moon because of it's colour

Hi,
Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.
- In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).
- In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.
- To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.
<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding.
</em>
Hope it help!
Answer:
Prophase → Metaphase → Anaphase → Telophase (PMAT)
Explanation:
Answer:
The correct answer is All of the above. In nature there are four forces, (also called interactions or fields in Physics) that are responsible for all phenomena in the universe: the gravitational force or interaction, the strong interaction, the electromagnetic and the weak nuclear.
Explanation:
The fundamental interactions or forces that describe all the interactions between the constituents of matter are each of the interactions that matter can undergo and that cannot be decomposed into more basic interactions. There are four basic forces that describe all interactions: Gravitational, that is responsible for the interaction between particles with mass and, by extension, for the configuration on a macroscopic scale of the Universe and its stability. Electromagnetic, is responsible for the interaction between electrically charged particles and, by extension, for all Chemical reactions, Weak is responsible for the disintegration of certain unstable particles; that is, of those processes in which some particles decompose (decay) into lighter ones and Strong interaction is the most complicated interaction to describe due to its different behaviors at different action distances; by means of which a global vision of the to physics without breaking it down.
