Answer:
In simplest terms, water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands.
Explanation:
Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
Answer:
The calcium concentration must be greater OUTSIDE
the cell than INSIDE the cell.
Explanation:
Calcium has a vital role in the body, it is necessary for:
- exocytosis
- muscle contraction
- normal excitability of neurons
- blood coagulation
- building and maintaining bones and teeth
- enzymatic activity
Molecules really can free neutrons, yet they can't lose protons in the event that they are to continue as before component. Loss of neutrons changes the molecule into an isotope of its essential structure. ... Loss of protons would change the molecules nuclear number.
It is the structure of our body, so like a tent, the poles help hold the tent up, without our bones, we’re just a meat sack
