In order to test the implications of early emotional bonding, scientists have done testing on infant emotionality by separating
timofeeve [1]

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.

Seismologists inge lehamann studied earthquakes. Which layer of earth did she predict to be solid after observing the motion of
arsen [322]

Inner core  was found to be solid after observing the motion of P waves.

Explanation:

Seismologist Inge Lehmann, studied the seismic waves of an earthquake and discovered about inner core in the mantle layer of Earth. She States that there is a boundary of discontinuity between the outer and inner core of Earth.

She studied the travel of secondary and primary waves during an earthquake and how it flows at different shells of Earth's layer which helped her in finding about the inner core of mantle. She observed that the inner core is a solid layer inside the molten layer of outer core

quzilet Which of the following occurs when DNA is replicated? Group of answer choices One strand of the parent DNA is preserved;
Bad White [126]

Answer:

The two strands of the parent DNA are separated, and two daughter DNA strands are formed.

Explanation:

DNA replication is a complex process which replicates or produces new DNA molecule from the parent DNA molecule mediated by enzymes and ATP.

The mechanism of DNA replication is known as the semi-conservative mode in which one new strand of DNA is synthesized complementary to the one strand of DNA. To form a new DNA molecule both the strand of the DNA gets separated and then a new daughter strand is formed complementary to each parent strand.

Thus, the selected option is correct.
