Cladodes<span> (also called cladophylls or phylloclades) are shoot systems in which leaves do not develop; rather, the stems become flattened and assume the photosynthetic </span>functions<span> of the plant. In asparagus ( Asparagus officinalis; Asparagaceae), the scales found on the asparagus spears are the true leaves.</span>
The best answer is D.
Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.
In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached mRNA is decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.
<span>Similarities and differences between intramembranous and endochondral ossification<span>
Ossification is the process of bone formation. Intramembranous and endochondral ossification are the two main processes of bone formation that occur during fetal development.
</span>Similarities between intramembranous and endochondral ossification<span>; they turn cartilage into bones during bone formation and they both involve bone cells such as calcium, vascular supply and osteoblasts.
</span>Differences between intramembranous and endochondral ossification<span>; In intramembranous ossification, an intermediate cartilage is not involved, rather the bone tissue is directly laid on a primitive connective tissue called mesenchyma while in endochondral ossification, cartilage is used as a precursor for bone formation. Also, in cases of fractures, the healing process by plaster of Paris occurs through endochondral ossification while fractures which are treated by open reduction and internal fixation are healed by intramembranous ossification.

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
