Answer:

1. Parasitism (+/-)

2. Mutualism (+/+)

3. Commensalism (+/0)

Explanation:

In biology, symbols are often used to differentiate between different types of symbiosis - a certain relationship between organisms, which could be beneficial, harmful, or neutral.

To distinguish between parasitism, mutualism, and commensalism, biologists use the positive (+), negative (-), or neutral (0) symbols.

1. Parasitism (+/-)

One organism benefits from the other and the other one gets harmed. For example, the Gordian worm infects a cricket. It gets nutrients from the cricket and once it is fully grown and able to reproduce, it leaves the cricket's body. The cricket eventually dies. This indicates that the cricket doesn't receive any benefit, but the opposite.

+ gains (parasite); - loses (host)

2. Mutualism (+/+)

Both organisms benefit each other. For example, the algae and the coral. The corals provide protection and refuge, plus nutrients the algae need for photosynthesis and, in turn, the algae provides oxygen.

+ gains (coral); + gains (algae)

3. Commensalism (+/0)

In this relationship, one organism benefits the other while the other neither benefits nor is harmed. For example, the leopard shark and remoras. Remoras attach to sharks with the aim of travelling to further areas without spending energy and the leopard shark doesn't get harmed nor is benefited by the remoras.

+ gains (remoras); 0 not benefited, not harmed (leopard shark)

gHow would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would reduce cAMP levels and inhibit

Ksivusya [100]

<h2>cAMP and glucose mobilization</h2>

Explanation:

It would maintain high cAMP level and elevate glucose mobilization

Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood
