The cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.

The sarcolemma is the plasma (excitable) membrane of muscle cells, which are surrounded by endomysial connective tissue.The T-tubules are invaginations of the sarcolemma that enter into the muscle cell in order to form interconnected networks.These tubules (T tubules) store intracellular calcium ions under the supervision of membrane depolarization through a voltage sensor channel (i.e., DHPR).

In conclusion, the cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.

Answer from: liyahguyton

The slow arrival of contraction or the slow onset of contraction.

Explanation:

The T tubules function in the transformation of the action potential from the sarcolemma to the sarcopasm reticulum.

In the skeletal muscles, it is located at the junction of the A and I bands but in the cardiac muscles, it is located only at the z discs thus giving rise to to T tubules.

The cardiac muscles also do not possess as much calcium as the skeletal muscles thus, its calcium ion must come from outside producing the slow arrival of contraction or the slow onset of contraction.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
