This picture (1st image) shows a fossil of an animal called Holophagus. Holophagus lived in the ocean and gave birth to live young.
Which traits did Holophagus have? Select the traits you can observe on the fossil.
Answer choices (2nd image; can choose more than one)
; long legs
; a tail fin
; a large red lump on its head
; two fins on its back
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.

What are the costs associated with water freezing and thawing? Who pays? Who should pay if there is an accident?
Answer:
The costs associated with water freezing and thawing can include damage to infrastructure such as pipes, sidewalks, and roads. This damage can be caused by the expansion of water as it freezes and contracts as it thaws. The cost of repairs and maintenance can be significant for both private and public property.
Explanation:
Who pays for these costs can vary depending on the specific situation and location. In some cases, the costs may be borne by the property owner, while in others they may be the responsibility of the government or a utility company. For example, if a private water pipe bursts due to freezing, the homeowner would typically be responsible for the repair costs. However, if a public road or sidewalk is damaged by freezing and thawing, the government or municipality may be responsible for repairs.
In the case of an accident, such as a water main break due to freezing, the responsible party would typically be liable for the costs of repairs and any associated damages. This could be a government agency, a utility company, or a private property owner, depending on the specific circumstances. In some cases, insurance may cover the costs of repairs and damages.

Explanation:
Last semester, we learned how tropism can affect the way a plant grows and moves. Explain how one or more of these tropisms help plants to survive. Include specific details about how the tropism(s) help plants survive.
HELP
Phototropism - a plant's growth response to light
Hydrotropism - a plant's growth response to water
Geotropism - a plant's growth response to gravity
Thigmotropism - a plant's growth response to touch
Use at least 5 sentences.
Include specific details about how the systems are working together.
Phototropism helps plants survive by allowing them to grow towards a light source. This helps the plant to maximize its exposure to sunlight, which is essential for photosynthesis, the process by which plants produce their food. This allows the plant to grow taller and bigger, which also helps it to compete with other plants for resources.
Hydrotropism helps plants survive by allowing them to grow towards water. This allows the plant to absorb more water and thus increase its chances of survival in dry conditions. This is especially important for plants that grow in desert-like conditions.
Geotropism helps plants survive by allowing them to grow towards gravity. This helps the plant to anchor itself firmly in the ground, which helps to prevent it from being blown over by the wind. This is especially important for plants that grow in windy environments.
Thigmotropism helps plants survive by allowing them to grow towards touch. This allows the plant to wrap around other plants or objects for support, which helps to prevent it from falling over. This is especially important for plants that grow in dense, crowded environments.
All of these tropisms work together to help plants survive by allowing them to grow and adapt to their environment in the most efficient way possible. For example, a plant would use phototropism to grow towards the light, hydrotropism to grow towards the water, geotropism to grow towards the gravity and thigmotropism to grow towards touch to be able to survive in its environment and get the resources it needs.
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?
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.
