Answer;
"couples" energetically unfavorable reactions to ATP condensation in order to drive the reaction toward the required product.
Explanation;
-Metabolic pathways are designed to synthesize necessary cellular reagents as required for cellular and tissue function. To accomplish this, the reaction sequence includes both reactions that are essentially irreversible and reactions that are freely reversible (near equilibrium).
-In most cases, cells use a strategy called reaction coupling, in which an energetically favorable reaction (like ATP hydrolysis) is directly linked with an energetically unfavorable (endergonic) reaction.
Answer: Bob received the gene for colour blindness from his mother.
Bob's genotype is likely XbY.
Explanation: Colour blindness is a disorder in which a person is unable to distinguish certain colours such as green and blue. Colour blindness is an X-linked (sex-linked) disorder, which means that colour blindness are carried on the X chromosome. Males are usually the sufferers because they have only one X chromosome which once affected will result in colour blindness while females are usually the carriers because they normally have two X chromosome and hardly do they have the two chromosomes affected except if the person is from a mother who is a carrier and a father who is a sufferer.
Bob's parents are likely to have one female with normal vision XBXB, one female who is heterozygous for colour blindness (a carrier) XBXb, a male with normal vision XBY and another male who is colourblind XbY.

Answer: The names of these groups are derived from the number of cotyledons or seed leaves that the embryonic seedling has within its seed. A monocot, which is an abbreviation for monocotyledon, will have only one cotyledon, and a dicot, or dicotyledon, will have two cotyledons.
