The plateau portion of the action potential in contractile cardiac muscle cells is due to the <u>membrane potential remaining almost constant</u>.

As the membrane gradually repolarizes This will be brought on by the nearly equal movement of charge into as well as outside of the cell.

As a result of this activity, the action potential reaches a plateau because a significant amount of calcium and sodium ions are transported through these channels towards the interior of such cardiac muscle fiber.

The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

vaieri [72.5K]
<span>I can infer that the importance of the Y is yellow and prevailing is the allele mix Yy is for yellow seeds. Yy implies that the phenotype demonstrated will mirror the capital letter, or the overwhelming one, which ends up being yellow. In the allele combination Yy, the Y is more dominant over y. If the combination equals yellow seeds, therefore, Y must be yellow seeds</span>
