To find an angle you use a variable like x or y. Sincw its a straight angle, it would be x +103 = 180. then you would subtract 103 on both sides. then you'll get x= 77 degrees
The male chromosome b/c the males have the XY DNA in their sex cells
It occurs during Anaphase II, Telophase II, and Cytokinesis, when the sister chromatids separate so that there is 1 allele per gamete.
<span>A tiger looks so much different as an adult than it did as a single fertilized egg because it developed through different stages from being a zygote (fertilized egg), to becoming an embryo (where it experiences intense cellular changes), to becoming a fetus (where it gains a great measure of cell specialization, and develops distinct tissues and organ systems). After birth, the tiger still undergoes further growth and development into adulthood. This is largely regulated by the expression of different genes at different times and also by environmental factors.</span>
