Answer:

Types of Roots : Roots are of two types viz. (a) Tap roots(normal or main) and

(b) Adventitious roots.

(a) TAP ROOT-Here the radicle prolongs directly to form a main primary roots when the primary root becomes stronger and persistent, it forms the tap root e.g. roots of dicotyledonous plants.

Primary root forms tap root, its lateral branches are secondary roots; branches of secondary roots in turn produce tertiary roots and so on. The tap root with its branches forms the tap root system.

The sequence of nucleotides in a messenger RNA molecule (mRNA) is determined by the sequence of nucleotides in a a transfer RNA

Answer:

D-DNA molecule

Explanation:

The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and it involves the unwinding of the DNA double strands molecules by enzyme DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.

The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.

The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.

How is stomach acid neutralized in the small intestine

Bingel [31]

"It converts the inactive enzyme pepsinogen into the active enzyme pepsin, which is responsible for digesting proteins in your stomach. HCL also helps digest other foods in your stomach. Ultimately, HCL is neutralized by chemicals secreted in your small intestine." But, use your own words, though. Because I just hit copy & paste. Hope this helps!
