Answer:
giraffes necks consists a tall bone like structure called notochord which gives support to the skeletal system like how do we have backbone
Answer:
S strain
Explanation:
The Avery experiment demonstrated DNA is the genetic material. It expanded upon the findings made by Griffith.
They used Pneumococcus; Smooth strain which was virulent and the Rough which was not.
Cultures of heat killed smooth strain were prepared after which it was treated with DNases ,RNases and Proteinases to remove DNA, RNA, and proteins respectively. It will then be introduced to living Rough strain.
When treated with RNases only the RNA will be destroyed and transformation will take place leading to colonies of S stains being formed.
Only when treated with DNase did the colonies S strain fail to be formed.
The integumentary system is the skin. Skin protects the inner organs from Bactria. Essentially the skin is a wall protecting against the outside world. It doesn't really release anything but is just there for protection.

A dihybrid cross is defined as a breeding experiment involving parental generation chromosomes that have two contrasting traits. The individual organisms involved in this can be either homozygous or heterozygous.
This kind of cross pollination experiments led to the development of George Handel's Law of Independent Assortment.
