AraC protein certain to the ara
operator works as a repressor that avoid transcription of the same ara operon
and the araC gene AraC protein is an activator in the presence of arabinose and
repressor in the absence of arabinose -With arabinose absent, the AraC protein
stays as
a homodimer. One AraC protein put together to the ara initiator and the other
protein now binds to a different regulatory site in DNA called the ara operator.
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:
Option D When activated, Bax and Bak form oligomers in the outer membrane of mitochondria, leading to the release of cytochrome c.
Explanation:
The proapoptotic genes are involved in the process of apoptosis. The antiapoptotic gene prevents apoptosis that is cell death. The proapoptotic genes are bax, bak, bad and bid. The bcl family genes are antiapoptotic genes. The process involved activation of apoptosis inside the cell is called intrinsic pathway of apoptosis.
The activation proapoptotic genes, Bax and Bak form oligomers in the mitochondria outer membrane. These pores in the mitochondrial membrane allows the release of cytochrome-c that further attaches with Apaf-1. This leads to activation of caspase 9 that further activates caspase 3, thus inducing apoptosis.
The diaphragm is the large flat muscle. hope that helps :)
