Answer:
The correct sequence is 3,1,4,2 and 5.
Explanation:
In the reflex arc, a signal is generated by the sensory cells and is conducted with the help of interneurons and returns back using motor neurons to bring out the reflex. The nerve pathway taken by a reflex action is known as a reflex arc. In the process, a receptor situated in the skin determines a stimulus. After that the sensory neuron transmits electrical impulses towards a relay neuron, and this relay neuron associates sensory neurons to the motor neurons. The motor neurons further transmits electrical impulses to an effector. The effector eventually generates a response.
The blending of different disciplines like geology, biologists, hydrologists and foresters can present both challenges and opportunities to the environmental scientist. The discipline like geology can involve someone used to mining and the destruction of ecosystems like mining down through lakes in open pit mines which is detrimental to the environment, but on the other hand the geologist can choose the best soil for growing grass on to feed the wild deer and moose on the reclaimed waste dumps, for example.
The difference between bacterial cells and animal cells is that animal cells have a membrane surrounding their nucleus while bacterial cells do not have membrane surrounding the nucleus.
DIFFERENCE BETWEEN BACTERIA AND ANIMAL:
- Bacteria and animal are both living organisms, however, they are distinct in the possession of membrane bound organelles.
- Bacteria are prokaryotic organisms meaning that they do not possess a membrane-bound nucleus in their cells.
- On the other hand, animals are eukaryotic organisms meaning that they possess a membrane-bound nucleus.
Therefore, the difference between bacterial cells and animal cells is that animal cells have a membrane surrounding their nucleus while bacterial cells do not have membrane surrounding the nucleus.

Codon-anticodon bond (bonding tRNA to mRNA)
Answer:
atoms
Explanation:
all things in the universe are made of atoms and they are considered the fundamental unit of matter.
non-living things are composed of different compounds and molecules.
living things are made of cells, and cells themselves are made of different molecules. So living things are also made of atoms.
