Hi, I hope you’re having/ had a good day
To answer your question, some creatures inflict all manner of horrible torments on others in order to feed and reproduce, or even just to play. Many species across the animal kingdom are cannibals, eating members of their own species for sustenance or dominance
Hope that helps :)
Answer: option D
In generalized transduction, any DNA can be moved while in specialized transduction certain DNA from the phage site is moved.
Explanation:
Transduction is the process where foreign DNA is added to a cell by a virus or viral vector.
Transduction is divided into two, generalized and specialized.
Generalized transduction is a process where any DNA can be transferred by the virus in the cell while specialized transduction is a process where a fragment of the DNA near the phage site can be moved.
Answer:
Sonic Hedgehog.
Explanation:
Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.
Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations
