Answers

Answer 1

Answer:

b) a tail fin

d) two fins on its back

Explanation:

The traits that can be observed on the fossil of the Holophagus are a tail fin and two fins on the back. These adaptations suggest that Holophagus was well adapted for an aquatic ocean lifestyle, possibly indicating that it was a proficient swimmer.

The presence of both tail fin and back fins would have provided Holophagus with increased maneuverability and control in the water, allowing it to navigate its environment with ease.

Identical twins share all of their genes, while fraternal twins share only half of their genes. For twins with the disorder schizophrenia, about 50% of indetical twins share the disease, while only about 10-15% of fraternal twins do. What does this tell you about the way genetic and envionmental facotrs affect schizophrenia?

Answers

Answer: The environmental factors likely interact with genetic liability negatively to produce disorders in the schizophrenic spectrum. Genetic and environmental components of the disorder are examined, as well as their interactions in producing either neurodevelopmental syndromes or schizophrenia itself.

Explanation:

The differences between identical and fraternal twins are due to how they are conceived. When identical twins are conceived, the fertilized egg splits into two, causing two separate embryos to grow. When fraternal twins are conceived, two eggs are fertilized at the same time.

Many factors normally contribute to the onset of schizophrenia

The actual causes of schizophrenia are not fully understood.

Brain chemistry: Abnormal functioning of neurotransmitters such as dopamine can cause schizophrenia.

Heredity: Schizophrenia tends to run in families. If a parent has the disorder, the offsprings are susceptible to the disease.
