Answer:
Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.
Explanation:
Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.
Answer:
2) is chemically specific
Explanation:
Enzymes are organic catalysts which speed up or control chemical reactions in cells. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reaction. Enzyme salivary amylase found in the mouth only hydrolyses starch into maltose.
Answer:
in male lion, two methyl groups are present in its structure while in female lion, two hydroxl groups are present in its structure
Explanation:
The chemical structure of the carbon atom is different in both male and female lion because both male and female lions have different sex harmones which are totally different from one another. In male lion, testosterone is a sex hormone whose chemical formula is C19H28O2 and two methyl groups and one hydroxl group are present in its structure while in female lion, oestradiol is a sex hormone having a chemical formula C18H24O2 and two hydroxyl groups are present.
Answer:
B. Traditional view
Explanation:
the traditional view is that nothing positive results from a conflict
The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
