Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. While for many this disorder

has little to no effect, for some it can be life-threatening. How could low levels of calcium harm an individual?
Low levels of calcium would not have any effect on synaptic transmission.
Low levels of calcium would cause sustained depolarization of the presynaptic cell.
Low levels of calcium would result in fewer signals sent between the pre- and postsynaptic cell.

Answer:

Hypocalcemia is defined as low level of calcium in the serum.

It could be harmful to an individual in the following ways:

Convulsions, arrhythmias, tetany, and numbness in the hands and feet and around the mouth occur due to lowered threshold for depolarization causing increased responsiveness.

Life-threatening complications- Laryngospasm and Cardiac arrhythmias can arise.

Effects on cardiac output include:

(A) Negative chronotropic effect, or a decrease in heart rate.

(B) Negative inotropic effect, or a decrease in contractility

The sporophyte of what plant group consists of evenly forking photosynthetic stems that lack roots and leaves?
Agata [3.3K]

The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.

Whisk ferns are the elementary and simplest vascular plants.

They contain small-sized protuberances which are called ' enations.'

In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.

Moreover, roots and leaves are absent in these plants and are composed of forklike stems.

To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.

How do intracellular communication and intercellular communication differ? Intracellular communication occurs between two cells.
pentagon [3]

Intercellular communication involves an electrical charge moving along a cell membrane. These are communicated through electrical charges flowing in between the cells like in the synaptic gaps of neurons.

Explanation:

Cellular communications are essential for the cell to communicate and control the various cellular activities both within and outside the cell.

Explanation:

Intracellular communications are those which take place within a cell. These signaling pathways also referred transduction pathways are triggered by extracellular communication signals which transmit through biochemical interactions to the nucleus. Eg., action of cyclic AMP.

Intercellular communications is the transfer or communication of information in between cells. These signaling pathways are communicated directly and indirectly. . Eg., neuron transmission and hormone secretion .
