Answer:
Germline mutations
Explanation:
Mutation in the cancer critical genes leads to the formation of stable mutant protein whose accumulation leads to the origin of cancer cells. Mutant p53 proteins not only lose their tumor suppressive activities (P53 gene is a tumor suppressive gene) but often gain additional oncogenic functions that allow for uncontrolled division of cells allowing increased growth and survival advantages. the same also goes for the retinoblastoma gene which is also a tumor suppressor gene that regulates cell division and other cellular activities. This mutations are usually inherited and can be transfered to their offspring.
 
        
             
        
        
        
Answer:
 ( please like and hope it helps)
A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table. 
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus. 
(Loxodonta and Mammuthus can also be reversed) 
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
 
        
             
        
        
        
Answer: Options A, B, C, D at correct
Explanation:
Cnidarians are a branch of invertebrates characterised by by a radially symmetric body including a saclike internal cavity and nematocysts; stinging structures that aids in feeding. They are also known as coelentrates. They are diploblastic (2 body layer). They also reproduce asexually by various mean including budding. Example include sea anemones, hydra, corals, jellyfish etc
