Answer:
The answer to the question: In terms of what is happening within a resting skeletal muscle cell, why are myosins not able to attach to the thin myofilaments, would be: because there is no presence of calcium ions to enable to fusion of the two.
Explanation:
When muscle cells, and a muscle in general, wish to perform one of their functions, which is movement, there are some factors that need to be present in order for this to work. One vital factor is the presence of calcium ions, because it is calcium which will enable the proper formation of the myosin-actin cross bridges for movement. Basically, calcium allows the removal of the protection on these filaments and makes them active, so that they will immediately seek the formation of the cross-bridges. To stop this from happening, calcium is re-absorbed by the sarcoendoplasmic reticulum.
According to Bio-chemistry experts, a poison is a natural or synthetic substance which causes damage to the tissues, and may cause harmful effects on organisms body.
The effects are based upon how the poison came into contact, which can be,
<em>ingested, inhaled, or absorbed or injected through the skin.</em>
The toxicity of a poison is characterized into two types, as follows;
- <em>Acute toxicity,</em> and
- <em>Chronic toxicity.</em>
The basic difference of Acute poisoning and Chronic poisoning is that, in Acute poisoning the effects came out immediately and are considered to be reversible,
but in Chronic Poisoning the effects can be delayed and came into observation later on, and experts had identified the effects of this poisoning as irreversible. for example, Lung cancer and smoking.

Answer:
The correct answer is option E. only water-soluble hormones use second messengers.
Explanation:
Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,
These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.
Thus, the correct answer is option - e. only water-soluble hormones use second messengers.
