<span>Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing and repolarizing during each heartbeat. It is a very commonly performed cardiology test.

The chromosome number of the four resulting gametes with respect to the normal haploid number shows <u>n + 1; n + 1; n - 1; n - 1</u> <u>(option A)</u>.
During aligning of all the homologous chromosomes, in the process of meiosis, new cells are formed.
From the total number of chromosomes one chromosome is missing , the resulting chromosomes are +1 and -1. Similarly for the second cell, resulting chromosomes would be +1 and -1.
This makes four gametes i.e. -1 and -1 and +1 and +1 respectively.

The geologic time scale is a system of chronological dating that relates geological strata to time, and is used by geologists, paleontologist, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. Hope I helped!
Answer:
PGALD or Phosphoglyceraldehyde is an aldehyde compound where as pyruvate is Ester derivative
Explanation:
Difference between PGALD and Pyruvate
1 PGALD is the reduced from of phosphoglyceric acid where as pyruvate is the oxidized from of glucose.
2 PGALD is formed in the dark reaction of photosyntheis but pyruvate formed at the end product of glycolysis.
3 PGALD is used is in the regeneration of Ribulose bis phosphate(RUBP) where as Pyruvate is used in the formation of Acetyl CoA and also helps in the biosynthesis of Alanine by transamination process.
