Describe the effect that increasing the potassium ions initially had on the heart in this activity. Relate this to the resting membrane potential of the cardiac muscle cell. How well did the results compare with your prediction?

Answers

Answer 1

Answer:

When there is an increase in potassium within the cell, depolarization is generated

Explanation:

Depolarization is the intracellular increase of potassium in the cardiac cell, this is how the resting potential is reached, this state of the cell refers to the fact that the cell does not execute or transmit any signal, it is in a refractory state of signals, since it does not capture any, this is how it prepares and recovers for future action potential.

As the citric acid cycle proceeds from the entry of acetyl CoA to the production of succinate, two carbons enter the cycle and two carbons are released as CO2. Why is the cycle not considered complete at this point?

Answers

Answer:

The oxaloacetate used to initiate the cycle must be regenerated.

Explanation:

Krebs cycle start from the condensation of acetyl-CoA and oxaloacetate.
Oxaloacetate must be regenerate to complete 1 cycle.

Answer:

Because ATP is not produce yet.

Explanation:

The cycle is not considered as complete because the main product i. e. adenine tri phosphate (ATP) is not produced yet. The main product of cellular respiration is the production of energy in the form of ATP with the help of oxygen whereas water and carbondioxide are the byproduct as well as waste material which can be removed with the help of breathing so that's why the cycle is considered as incomplete.

What are amphibians?

Any member of the group of vertebrate animals distinguished by their capacity to utilize both aquatic and terrestrial environments is referred to as an amphibian (class Amphibia). The word amphibian, which means "living a double life" in Greek, refers to this dual lifestyle, even though some species are entirely aquatic and others are permanent terrestrial residents.

There are now 8,100 different species of amphibians. They first appeared during the Middle Mississippian Epoch, around 340 million years ago. They were one of the first groups to depart from the ancestors of fish-tetrapods when animals evolved from purely aquatic forms to terrestrial ones.

Frogs and toads (order Anura), newts and salamanders (order Caudata), and caecilians are today's amphibians (order Gymnophiona). Despite having remarkably distinct body types, these three groups of contemporary amphibians—which are assumed to have descended from a single radiation of prehistoric amphibians—are most likely the closest relatives of one another.

Therefore, the survival of amphibians is dependent on land and water resources.

ATP (adenosine triphosphate)

Answer: (ATP) Adenosine Triphosphate

Explanation: Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP.  ATP, or adenosine triphosphate, is chemical energy the cell can use. The process can be summarized as: glucose + oxygen → carbon dioxide + water. Adenosine  triphosphate is an organic chemical compound and hydrotrope that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.

Explanation:

Obsidian glassy texture indicates that the rock formed on the surface rapidly.

Like every other magma, the condition of the environment determines how the magma cools and solidifies.

When magma cools rapidly, nucleation centers will be difficult to come- by .. At nucleation centers, minerals aggregates and grows to form different grain sizes. When rapid cooling occurs, not enough time is given for the aggregation around the nucleus. This leaves a rock mass that is finely grained.
