Answer:
White Blood Cells
Explanation:
White blood cells are primarily responsible for protecting the body from infection. There are many different types of white blood cells. Some white blood cells are phagocytic and engulf invaders. Others produce antibodies that attack foreign substances or mark them for killing.
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.
The quantity of water in the water table can change rapidly depending on the rate of extraction. As the level of water decreases in the aquifer, there is less available water to be pumped. If the rate of potential groundwater recharge is less than the rate of extraction, the water table will be too low for access.
1.photosynthesis is anabolic while cellular respiration is catabolic
2.photosynthesis occur in the day while cellular respiration take place any time
