Answer:
A. Constipation
Explanation:
As there would be easy passage of faeces, based on an increase in roughage for the colon to press and rub against
The correct answer is mRNA.
mRNA or messenger RNA is synthesized during the process of transcription, from DNA molecule which is used as a template. mRNA contains information about protein synthesis (translation) in the form of nucleotide triplets or codons.
In the example above: reference book is DNA molecule (template for copies), copies are mRNA, wood is amino acids (building blocks) and doghouse is protein.
None...........................probably mars
<em>Electron microscope </em><em>is most likely to be used to produce a clear image of very tiny structures inside a cell</em>
Answer: <em>B. Electron microscope</em>
Explanation:
The electron microscope is a kind of magnifying instrument that utilises electrons to make a picture of the objective. It has a lot higher amplification or settling power than a typical light microscope. The tiny structures inside the cell are easily visible under the electron microscope.
The electron microscope can be scanning electron microscope or tunnelling electron microscope. Both the type of electron microscopes differ in function but uses electron as its source of illumination.
Answer:
a. Diameter of afferent astride is bigger than efferent arteriole to generate force for efficient filtration
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body
c. Always vasopressin is not secreted when a person drinks sufficient water
d. ESRD stands for End stage renal disease
Explanation:
a. While transferring blood from afferent astride to efferent arteriole blood gets filtered. Filtration is efficient when the blood flows with force which is generated when blood flows from large arteriole to the small arteriole. Hence the diameter of afferent astride is bigger than efferent arteriole.
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body. In summer water is lost in the form of sweat as well. Hence, urine gets concentrated to compensate for the lost body fluid.
c. Always vasopressin is not secreted when a person drinks sufficient water. The osmoregulation is maintained externally.
d. ESRD stands for End stage renal disease
