Answer:
Hydrophobic.
Explanation:
The plasma membrane or cell membrane is made of the lipid bilayer and the proteins are embedded in the this layer. Carbohydrates are also exposed to the cell surface in association with proteins and lipids.
The interior of the cell membrane is hydrophobic due to the arrangement of the lipid bilayer. The hydrophobic part of the lipid membrane are associated with each other that makes the interior of the cell membrane hydrophobic and small molecules easily diffuse through the membrane.
Thus, the correct answer is option (c).
Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
Answer: health information management; information technology
Explanation:
<em>With the increase in electronic health records, more professionals are working in </em><em><u>Health Information Management</u></em><em>, which requires a familiarity with the healthcare system, as well as </em><em><u>Information technology.</u></em>
<u />
The field of Health Information Management has seen a massive boost in recent years as more people train in this field which is necessary to input, analyze and protect the electronic health records of people.
Doing this job requires one to be well versed in both healthcare systems so that they have a familiarity with the data they are to manage, as well as information technology so that they can manage the electronic data.
4.) The record keepers opinion of what the problem is.
Answer:
Skeletal muscle can contract without shortening.
It can shorten (isotonic, concentration), elongate (isotonic,eccentric), or remain the same length (isomertric), depending on the relationship between the load (resistance) and the tension produced by actin-myosin interactions.
