Answer:
Some sweet-pea plants have purple flowers and other plants have white flowers. A homozygous variety of pea that has purple flowers is crossed with a homozygous variety that has white flowers. All the F1 have purple flowers. When these F1 are self-fertilized, the F2 appear in a ratio of 9/16 purple to 7/16 white. Show your work.
A) Give genotypes for the purple and white flowers in the F2 generation.
PP x ww= Pw, Pw, Pw, Pw F1 generation
Pw x Pw= PP. Pw, Pw and ww F2 generation
3 purple and 1 white flower
B) Draw a hypothetical biochemical pathway to explain the production of purple and white flowers in sweet peas.

Answer: C. Very Large Array </h3>
There are 28 radio antenna, which are essentially satellite dishes. Only 27 are in operation at any given time, leaving one to sit out for maintenance. Astronomers using this array were able to observe black holes, and also observe the formation of interplanetary disks, among many other applications as well.
The reason why so many dishes are used is to increase the faint signal that is received from such a long distance away (often lightyears away). The 27 dishes are effectively the same as having a single radio dish that is 36 km (22 miles) in diameter. Having such a impossibly massive satellite dish is not feasible, so it's more practical to go with 27 smaller dishes.
The hierarchy that best captures this information is that; mammal is a superclass of Rodent and Mammal.
Mammals are members of the group of vertebrate animals in which the young ones are nourished with milk from special mammary glands of the mother. Additionally, mammals are distinguished by several other characteristics such as Hair, hinged lower jaw directly to the skull., among other characteristics.
