An electrocardiogram (ECG) provides information about B) the rhythm of heart contractions
The rhythm of heart contractions can be known by an electrocardiogram (ECG).
An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.
The process to measure the electrical signals of the heart can be done by using this machine.
In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.
It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.
It consists of QRS complex which measures the heart beat.

Hydrochloric acid is a strong acid (fully dissociates when dissolved in water due to the polar covalent bond)
It is a very stable molecule
It is highly reactive with metals and with oxidising agents such as organic materials, alkalis, water etc.
Can be extremely corrosive if solution is concentrated.
A rabbit is a primary consumer
The answer is <span>potato.
Potato is a stem tuber while carrot, beetroot, and radish are true root crops and not tubers.

Tuber is a structure that provides nutrients for the next season regrowth. It is specialised for asexual reproduction. Potato is a stem tuber, for example. In one growing season, the tuber is produced and used to perennate the plant. In the autumn, when the plant structure above-ground dies, the tuber survives underground over the winter. When spring comes, tuber regenerates new shoots thanks to nutrients stored. On the other hand, true root crops (carrot, beetroot, radish) are modified roots to store energy but they are not specialised for asexual reproduction.
Taxonomy used to have two groups of vertebrates and invertebrates. But invertebrates are far more diverse when it comes to the phylogenetic tree. Vertebrates all share same characteristic which is a back bone made of vertebrae, but invertebrates don’t share a common anatomical structure that all have; they are radically different in structure so they can’t be grouped in a single group. You have Arthropoda, which all have jointed limbs and segmented bodies and molt their cuticles. There’s Cnidaria, which most have tentacles and nematocysts and are radially symmetrical. And Mollusca, which have a muscular foot and a part of their body called a mantle. All these groups are invertebrates, but there’s nothing they share in common WITHOUT referring to the fact that they don’t have vertebrae. So basically that’s just an example why they can’t be grouped into one category; they all have different characteristics and are placed in different areas of the animal kingdom’s phylogenetic tree. Hope this helps
