Winter in the Northern Hemisphere begins December 21 or 22, when the North Pole is tilted a full 23.5° away from the sun. This day is known as the winter solstice. In June, in the northern hemisphere summer, the Sun's rays — and warmth — reach all the way to the north pole.

In June, in the northern hemisphere summer, the Sun's rays — and warmth — reach all the way to the north pole. In December, in the northern hemisphere winter, the north pole is tilted away from the incoming sunshine.

Answer: Option C.

<u>Explanation:</u>

Prokaryotic cells are the cells that do not possess a true nucleus. They do not even possess a membrane bound organelles. Organisms with in the domains bacteria and Archaea have prokaryotic cells. The other forms of life are the eukaryotic.

It is a unicellular organism. The word prokaryotic comes from a Greek word. The prokaryotic cells have a cell membrane or a plasma membrane which acts like a protective shield. Along with this, they also have a rigid cell wall which acts like further support and protection.

If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures

Brilliant_brown [7]

Though there's no question in the statement above I would assume that you are asking about the pH of the water that is acidic. The correct statement would be:

Any liquid that has a pH less than 7 is called acidic, a pH above 7 is basic or alkaline.

The water in the swimming pool has a high acid concentration due to the chlorine which causes the effect of redness in the eyes.

12345 [234]

Answer:

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

Explanation:

pre-mRNA, mRNA, rRNA, RNA primers, snRNA

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
