Answer:
False
Explanation:
The majority of cardiac muscle cells also known as cardiomyocytes of myocardiocytes have one nucleus even though they might have as many as four.
Answer:
This probably because they destroy a given character or give rise to a new one.
Explanation:
Alteration here are the permanent changes found in the DNA structure. And are totally inheritable. An example is the case of sickle cell anaemia and haemophilia. People with this anaemia trait hardly live and reproduce even though they do not show ill effects.
Therefore, this mutation alteration is harmful because they destroy a given character.
Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.
