Answer:
Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions. Therefore it turns red litmus blue and phenolphthalein solution pink.
1. If we cross YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits)
P: YyLl x yyll
F1 generation: YyLl: 400 Yyll: 100 yyLl: 100 yyll: 400
Recombinant offspring are those children whose genes contain a non-parental allele combination (neither allele group is directly inherited from either parent). This happens when genes are located on the same chromosome but are so far apart from one another so that their alleles get crossed over during meiosis. In this case, Yyll and yyLl are the recombinant.
2. Calculation of distance between Y and L.
The numbers of the two recombinant types is 200 (100 Yyll + 100 yyLl) and 800 parental offspring.
Total number of offspring is 1000.
So: 200/1000*100=20 map units.
There is 20 percent recombinant offspring frequency.
Ginkgos have many angiosperm-like features
Answer:
there is an association between the number of mitochondria in muscle cells and energy production
Explanation:
Mitochondria generate energy by generating adenosine triphosphate (ATP), which is referred to as the "molecular unit of currency" of the cell since this molecule provides energy for diverse cellular processes
