Answer:
a. Ed/eD
b. RF=0.12
Explanation:
The alleles for genes D/d and E/e are:
- D_: only on neck spikes
- dd: along back spikes
- E_: long spikes
- ee: short spikes
After testcrossing a double heterozygote (DdEe x ddee) there are 4 types of offspring, two of them much more abundant than the other two. The homozygous recessive parent can only produce <em>ed</em> gametes, so the phenotypes of the offspring depend on the gametes that the double heterozygous parent produced.
The offspring was:
- Ed/ed 79
- ed/ed 12
- ED/ed 10
- eD/ed 76
Total: 177
a) This result suggests that the genes are linked. Since recombination is a rare event, the most abundant phenotypes always come from the parental gametes, and the least abundant come from the recombinant gametes.
<u>Therefore, the genotype of the doube heterozygote parent was </u><u><em>Ed/eD</em></u><u>.</u>
b) Recombination frequency (RF) = Recombinants / Total
RF = (12+10)/177
<u>RF = 0.12</u>
ATP is used and released during the metabolic processes.
<u>Explanation:</u>
In the process of Respiration, a glucose molecule is eventually broken down into carbon dioxide and water. During this process, some ATP is produced directly in the reactions that transform glucose. However, more ATP is produced later in a process called oxidative phosphorylation.
Oxidative phosphorylation takes place by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
Fermentation process takes place when the availability of oxygen is less. In this process glucose instead of converting into CO2 and water gets converted into lactic acid or any other alcohol.
The chef cuts the steak into two halves, it is a physical change, because the color and/or odor do not change, in which change in smell and odor is characterized as chemical change.
the chef melts the ice on the vegetables by leaving it outside in the kitchen in normal temperature, (assuming the kitchen is around 20+ celsius degrees).
it is physical change because only the shape changes, the color and/or odor do not change.
