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

Anton [14]

Answer:

The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state

What does it mean to be sustainable?
lord [1]

Answer:

To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable.

Another example is if a country only has about 10-13 crimes a year for 20 years, crime is sustainable in that country.

A cross between two pea plants, both of which grew from yellow round seeds, gave the following numbers of seeds: 156 yellow roun
LiRa [457]

Answer: The correct answer would be YYRr and Y_Rr

Explanation:

Let us denote Y and y be the alleles of the gene responsible for seed color and R and r be the alleles of the gene responsible for seed shape. Capital letter is for dominant allele and small letter is for recessive allele.

Being dominant traits, both the parents should have at least one dominant allele of both the genes. It is because the phenotype of both parents is yellow and round seeds.

In addition, F1 shows single phenotype for seed color but both phenotype for seed shape. The presence of recessive phenotype in F1 indicates that both the parents must be heterozygous for seed shape, that is, Rr.

However, for seed color, it is possible that either one or both were homozygous, that is, either both YY or one parent is YY and another parent is Yy.

Where is the epicenter of this hypothetical earthquake
likoan [24]
The epicenter of a hypothetical Earthquake is the place where the fault begins to rupture. The tectonic movements within the epicenter is actually the area with the greatest damage after an Earthquake occurs.

The epicenter is the most dangerous zone during an Earthquake because the ground is very much unstable, but as the seismic activity dissipates it is the first one to set and stabilize because this is where the plates will converge.
