Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.

Answer:
The correct answer would be
- They are vase-shaped
- Their tentacles trail down from their mouth.
Coral polyps are small, soft-bodied organisms mainly belong to the phylum Cnidaria.
They have a vase-shaped body that is, their body is cylindrical in shape which is elongated at the axis.
They remain attached to the rocks present on the floor of the sea.
They have tentacles which help in capturing the food.
The tentacles surround the mouth which opens into a central cavity filled with fluid.
They can reproduce sexually as well as asexually.
In representing consecutive numbers, we may add one to the numbers if we wish to move right on the number line, while subtracting one from the numbers will allow us to move left.
Because b is the smallest of the four numbers, we will be moving right on the number line. Thus,
first number: b
second number: b + 1
third number: b + 2
fourth number: b + 3
