Answer:
True
Explanation:
Cardiac muscle cells appear striated. However, they are involuntary, unlike skeletal muscle cells, because they contract outside of human control. For example, you do not have to think about contracting your heart muscles as the already contract for you. On the other hand, skeletal muscle cells are controlled by humans as they decide which body movement to perform, such as walking or pointing.

Fossils are the remains, imprints, or traces of once-living organisms preserved in rock.
<span>The correct answer, according to Lamarck's theory of evolution, is that A) "Land mammals progressively modified their organs to survive in water. These features were passed on to the next generation, and the mammal gradually evolved into today's aquatic mammals."
Lamarck believed that animals could (a) acquire the traits that they needed and (b) pass those acquired traits on to their offspring. According to part (a) of Lamarck's idea, if I needed to be a faster swimmer (if I were an athlete), I could modify my body to have webbing between my toes, which would allow me to beat the competition! Also, according to part (b) of Lamarck's idea, if I were a body builder and developed (acquired) very large muscles through my training, then my children should be born with very large muscles. Based on the these examples, you can see why Lamarck's theory of evolution is not the one that is generally accepted by scientists. Rather, Darwin's theory of evolution, in which the traits that we are born with confer either an advantage or disadvantage to us in our particular environment, which determine whether or not we are successful (ie, survive and reproduce). New traits come about randomly by mutation, not by our need for them.</span>
