True.
It is easier since there are a lot of theories that could sum up and provide evidence to support that an object has life than life itself.
One popular theory is the cell theory which states that all organism is made up of cells, cell that came from those pre-existing cells, and reproduce by those cells themselves.
Answer:
D. A waxy coating on a plant
Explanation:
A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers. All the species of plants possess this waxy coating of cuticle because it plays important role in stopping the loss of water from the cells.

Explanation:in the process of the scientific method,an observation about an occurrence happens first before an hypothesis is formulated and tested .
Observation usually involves the the description of a phenomenon.
They are called cotyledons
The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.
An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.
The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.
This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.
