In order to test the implications of early emotional bonding, scientists have done testing on infant emotionality by separating animal babies from their natural mothers, allowing them to be raised by another of their same species. This testing strategy is called Cross fostering
- Transfer of children between mothers is known as cross-fostering. This method is used to distinguish between environmental and genetic impacts on behavior.
- Transferring some freshly born or hatched young of species A from their mother nest to the nests of species B is the primary process of cross-fostering.
- A behavior can be proven to have a genetic foundation if cross-fostered offspring have a behavioral attribute that is distinct from that of their foster parents and similar to that of their biological parents.
- Similarly, environmental variables are proven to be dominating if the offspring exhibits qualities that are different from those of their biological parents and comparable to those of their foster parents.
- There is frequently a combination of the two, demonstrating both genes.
- This can be utilized in selective livestock breeding to combine desirable genetic traits like weight, fat distribution, or looks with ones that are influenced by the environment, like temper.

Answer:
melanin affects how one looks (1st question)
cause and effect (2nd question)
Explanation:
for the 2nd question, its cause and effect because uv rays hit our skin and our skin is affected which gives us suntan.
The action that will directly affect the gravitational force between two objects is increasing the pressure on the objects (option B).
<h3>What is gravitational force?</h3>
Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons.
Gravitational force can also be referred to as the force due to gravity of a planet.
The gravitational force between two objects can be affected by the following factors:
- Increase in pressure
- Increase in temperature
- Increase in speed of objects
Therefore, the action that will directly affect the gravitational force between two objects is increasing the pressure on the objects.
