Answer:
D) observation that certain tumor-suppressor genes and oncogenes are involved in a sequential manner in the development of colon cancer
Explanation:
Cancer is defined as the abnormal growth of cells of the body. These cells multiply/replicate without control thereby forming a lump or tumor.
Cancer growth has 5 stages and they go though different multi level steps.Different finding backs this up and it includes observation about certain tumor-suppressor genes and oncogenes being involved in a sequential manner in the development of colon cancer.

Answer:
B
Explanation:
Faults are caused by all that bumping and sliding the plates do.
Because only the chromosomes can be seen in a karyotype, and microdeletions or insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.
Vascular plants have a vascular system while nonvascular plants have NO vascular system.
Explanation:
The vascular system is made of phloem – that transports food- and xylem- that transports water and minerals- in the higher plants. Examples of these higher plants are like trees and shrubs. These plants can take up water and nutrients from the soil and transport them up the plants to the leaves.
Lower plants have no vascular system (avascular). They mainly absorb food and water readily from their environment even through their leaves. This is why these plants are mainly found in humid areas like waterways, like canals. Examples of such lower plats are ferns and mosses.
