1. What causes the autorhythmicity or action potentials of the nodal cells? a. A decrease in chloride permeability b. A gradual
Sveta_85 [38]

Answer:

The correct answer will be option-C

Explanation:

The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.

The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.

This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.

Thus, Option-C is the correct answer.

How can a punnett square predict the traits of offsprings
Anna35 [415]

A punnet square predict the traits of offspring genetic crosses and test crosses.

<u>Explanation:</u>

In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.

The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by  genetic crosses. In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
