Sue's bones have become brittle,
fragile, and thin. Her doctor would most likely diagnose her with osteoporosis.
Osteoporosis is an age related bone condition that occurs due to the reduction of
the bone’s density and the body’s inability to produce as much bone as it initially
did. The bones become weaker and increase the risk of fractures, especially in
the spinal vertebrae.
Answer:
mitochondrion
Explanation:
Overall, the process produces the 2 pyruvate plus 2 molecules of water, 2 ATP, 2 molecules of NADH, and 2 hydrogen ions (H+). The NADH carries electrons to the oxidative phosphorylation step of cellular respiration, which occurs inside of the mitochondrion
Answer:
True

A certain bacterial mRNA is known to represent only one gene and to contain about 800 nucleotides. If you assume that the average amino acid residue contributes 110 to the peptide molecular weight, the largest polypeptide that this mRNA could code for would have a molecular weight of about _______.
A) 800.
B) 5,000.
C) 30,000.
D) 80,000.
E) An upper limit cannot be determined from the data given
Answer:
c. 30,000
Explanation:
The gene has a total of 800 nucleotides and would be transcribed into an mRNA having about 800 nucleotides. The nucleotides of mRNA are read in the form of genetic triplets. This means that the mRNA with 800 nucleotides would have about 800/3= 266.66 or 266 genetic codes. This mRNA would be translated into a polypeptide chain having around 266 amino acids.
One amino acid contributes 110 to the molecular weight. The total molecular weight of the largest possible polypeptide that can be encoded by the said gene would b 266 x 110= 29260 (around 30,000).
Answer:
Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.
