Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
Answer:
Employee boredom
Explanation:
When an employee specializes in a specific part of job, and it tends to be repetitive each day, it leads to Employee boredom
. Therefore, there should always be novel challenges and tasks in work place which do not make an employee feel boring about same monotonous work each day in which they are already specialized.
This never intends to mean that Job specialization is a bad thing, but there should be versatility in work because the work of repetitive nature tends to create a sense of boredom in person and makes his mind less creative as he is doing something daily on which he is expert and do not needs more learning.
Hope it helps!
Answer: James Watson and Francis Crick
Explanation:
In 1953 James Watson and Francis Crick are responsible for determining the structure of DNA. James and Watson proposed that the DNA is made up of a double polynucleotide chains that are twisted around each other to forming a helical structure. The two DNA chains runs anti-parallel in opposite direction to each other. Like the structure of the ladder.
The answer is James Watson and Francis Crick
Answer:
Look in explanation
Explanation:
The sun provides energy to plants. The plants are eaten by herbivore/omnivores transferring the energy from the plant to the herbivore/omnivore, then the carnivore eats the herbivore/omnivore which gives the carnivore the energy
Answer: it is made up of glucose and fructose
