Answer:
Calcium
Explanation:
Calcium is an important element present in the organisms body. The calcium can acts as an important messenger molecule and helps in the process of muscle contraction.
The concentration of calcium ions in the myoplasm leads to the development of force necessary for the movement of actin and myosin molecule. The calcium ions cling the cross bridge formation during muscle contraction.
Thus, the correct answer is option (b).
Answer:
D. inherited
Explanation:
I could be wrong but inherited conditions are those that run through the family so eventually it will come up in the medical history.
Answer:
The interaction between cellulose-digesting organism in the gut of a termite and the termite is +
Explanation:
This relationship that exists between termites and the organisms present in their gut that are capable of degrading cellulose is a relationship called mutualism. Mutualism is part of the biological interactions in which both organisms benefit from the coexistence of both. For this reason this relationship would be positive.
The food of termites is wood, but they cannot produce the enzymes they would need for degradation of the wood. Thanks to this, there are small organisms called protozoa that are found in the intestine of the termites that allow them to degrade the cellulose present in the wood, these organisms help them to degrade the cellulose that by themselves they could not do since termites do not contain the cellulose enzymes responsible for cellulose degradation .In this way TERMITES can get what they need to perform its metabolism and biological functions.
