Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.
- The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
- It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
- An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
- The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
- An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.

Answer:
True
Explanation:
sodium explodes when it contacts water
Their location, or layer
The cells produce three germ layers:
endoderm- becomes the gut
mesoderm- becomes muscle, skeletal system, some organs, and connective tissure
ectoderm- becomes skin and nervous system
<u>Nucleic Acid, and Protein</u> are the class of biomolecule which are the two main ingredients in plant fertilizer.
Biomolecules- A chemical substance that is present in living things is called a biomolecule. These consist mostly of substances with the chemical elements carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. The building blocks of life, biomolecules serve crucial roles in all living things.
Fertilizer- Any product or material given to soil to encourage plant development is referred to as fertilizer. There are many different types of fertilizers, and the majority of them include potassium, phosphorus, and nitrogen (N) (K). In actuality, the package of fertilizers bought in supermarkets lists the N-P-K ratio.

Answer:
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476
Explanation:
Given -
Purple flowers - 847
Pink flowers - 153
The frequency of recessive genotype i.e
Frequency of recessive allele i.e q is equal to
As per hardy Weinberg's first equilibrium equation -
Frequency of purple homozygous species
Number of purple homozygous species 
Number of pink homozygous species 
Heterozygous species is equal to
