Explanation: The snail breaths in the O2 which will then exhale CO2, therefore the plant will take that and process the CO2 back into O2.
A. Gametes are the male and female reproductive cells (Sperm and Egg) While body cells make up all organs, Stem cells are undifferentiated cells in a multicellular organism and somatic cells are any cells in the body other than reproductive cells.

Glad to help ya!! :)
Answer:
1. Ventricular depolarization −−QRS complex
2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval
3. Atrial depolarization −−P wave
4. Conduction through the atrioventricular (AV) node −−PR segment
5. Ventricular repolarization −−T wave
6. The ventricles are in their depolarized state −−ST segment
7. Conduction through the atrioventricular (AV) bundle −−Q wave
Explanation:
ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.
There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.
The Kingdom Fungi
The Kingdom Fungi live in all places and include molds, yeasts, mushrooms, rusts, smuts, puffballs, truffles and morels. There have been 70 000 species identified. The fungi is separate group from plants or animals although they appear like plants but intimately related to animals . It is microscopic.
