Answer:

The correct answer is option d) an interaction between nature and nurture.

Explanation:

This idea is supported by the interaction between nature and nurture. This means that all our genetically acquired aspects such as genes, inherited physical characteristics, etc. work together with the environment in which we grow, the relationship we observe in our family, the people with whom we interact and the environment in we were raised.

<u>Both concepts interacting with each other </u>form what is known as a language acquisition device.

Here it is established that all <u>children are born with the ability to learn language and reproduce it through what they observe around them</u>.

Be it the way your parents speak, the friends around you and anything in the environment that can influence this aspect.

IrinaVladis [17]

Answer:

Neighboring cardiac muscle cells in the walls of heart chambers have specialized cell-to-cell contacts that electrically and mechanically link the cells together, permitting the immediate passage of muscle impulses. These cell-to-cell contacts are called <u>intercalated discs.</u>

Explanation:

Intercalated discs can be described as unique structures present between the cardiac muscles of the heart. The intercalated discs play a major role in making the cardiac muscles contract in a rhythm so that the heart can pump blood in a regular fashion and it hence regulates the effective functioning of the heart. The intercalated discs are the structures that join on cardiac muscle to another and is involved in the transmission of chemical messages between them.
