Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
= 91 oranges
</span><span>
D. 91</span>
Answer:
four oxygen molecules
Explanation:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Answer:
correct option is A.
Succession is the process by which the structure of a particular community evolves over a specific period of time. There are two types of succession, primary and secondary succession. Primary succession is a type of succession that occurs in a place which is incapable of sustaining the growth of plants, that is, it usually occur on barren lands. All the options given above are examples of places for primary succession with the exception of option A.
D) orbit the nucleus like the planets orbit the sun.
this idea was first proposed in the rutherford model:)
Answer:
The tRNA is released from the E site of the ribosome and the elongation process finishes while the termination process starts.
Explanation:
When the translocation process is finished the tRNA that is in the E site of the ribosome is released and the A site of the ribosome reads a stop codon in the mRNA in order to finish the elongation process and start with the termination process. In the termination process a termination factor joins the stop codon, the ribosomal subunits split apart, the protein and the tRNA dissociate from one another and the tARN is not in the P site of the ribosome anymore.
