Answer:
a lack of resources and stability can be a major factor for this situation, meaning they dont have much of a choice. they become a nuisance to richer clients and are therefore removed and dumped away.
Answer:
<em>B. Methyl yellow, which changes from yellow to red around a pH of
</em>
<em>4.0</em>
Explanation:
A pH indicator is a technique by which the pH of a solution can be known. The scenario in the question describes that the scientist wants to determine a pH after it gets converted from 6 to below 4. For this recognition, the scientist should use a methyl yellow indicator which will change from yellow to red once a pH around 4 is achieved.
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<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>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 <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
Answer:
Sweating is under the control of the sympathetic nervous system, which orchestrates the body's reaction to stressful situations and emergencies. The sympathetic nervous system activates the sweat glands through the chemical messenger acetylcholine.
Answer:
a sense organ
Explanation:
this is because sense organs are part of nervous system
