Answer:
Explanation:
The body easily breaks down and digests carbohydrates. They provide quick energy.
Athletes need energy to continue through an activity. Athletes can benefit from carbohydrates because they will provide a boost of sugar that can be converted to energy/ATP in cellular respiration.
For a normal person who doesn't burn large amounts of energy and calories, too many carbohydrates still provide a large influx of sugar. But it isn't turned into ATP because the body has no need for the extra energy. Instead, it is stored as glycogen in the liver or triglycerides in fat.
So, carbohydrates aren't made of proteins and they don't contain hereditary information. That leaves choice<u> D as the correct answer: Carbohydrates store and release energy which would be helpful to an athlete who burns a lot of calories but, for the average person it would be stored as fat.</u>
Answer:
A,B and E
Explanation:
- I+: I refers to the lac repressor, the + indicates that the repressor is functional
- P+: P refers to the promoter region and the + indicates that the promoter is functional
- Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
- Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
- Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional
So based on the breakdown above:
- C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.
- D is not true because Z-, no β-galactosidase is produced.
Only A, B and E apply.
The answer is; codon, codon, anticodon
There are about 64 different combinations of three nucleotide bases into codons. The combinations, however, only code for 20 amino acids hence some codons are redundant. When the mRNA forms a scaffolding with the ribosome, the tRNA with the right anticodon (sequence complementary to the codon on the mRNA) to the codon on the A site of the ribosome, leaves its amino acid at the site of chain elongation (P-site) and exits at the E-site.
Abiotic factors can't determine which species of organisms will survive in a given environment. A forest fire is an example of abiotic factors.
