Answer:
Humans and marine organisms use sound finding depth of the ocean and objects.
Explanation:
Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.
Answer:
Corn crop is resistant to herbicides because they are genetically modified through genetic engineering. There are some bacteria which are resistant to herbicides i. e. no effect of chemicals on that bacteria. So the biotechnologist take a gene from this resistant bacteria and induced it in the corn plant which becomes the part of their genetic makeup. So when we apply herbicide, the gene produces some enzymes which cancel the adverse affect of herbicide and only weeds are affected.
Answer:
Peduncle
Explanation:
The Caudal Peduncle or Peduncle in this case is the muscular region that is found between the dorsal and an.al fins.
This Peduncle helps the fish to swim and navigate the currents in the water.
It helps to propel the fish to move quickly through water as it acts like a motor.
Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.
