Answer:D
Explanation:if your cell doesn’t produce enough enzymes it wouldn’t be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins.
<span>Prokaryotes don't have a nucleolus as they do not have a nucleus, and neither do they have a Golgi apparatus. A nucleoid is loose DNA which is found in prokaryotes but not in eukaryotes...</span>
Answer:
Positive is the correct answer.
Explanation:
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
<span>In theory, to gain a pound of body weight per
week, one must consume an additional 1,000 calories per day. An approximate
3,500 calories is equivalent to a pound of body weight. If a person
continuously consumes more than 3,500 calories over a period of time it is
expected that this person will gain 1 pound of weight. <span>
<span>Nutritionists
usually suggest that an
underweight person should add between 500-1,000 calories per day to encourage a
1-2 pound increase in body weight. Because being underweight sacrifices one's
immunity and overall health.</span></span></span>
