Both Jenny and Jack are correct.
Explanation:
According to the principle of superposition, both Jenny and Jack are perfectly correct.
The principle of superposition states that the oldest bed is at the bottom and the youngest is on top in an undeformed sequence of rock strata.
From this principle we can see that the sequence of the bed is:
- soil Youngest rock layer
- loam
- sand and gravel
- loam
- clay
- impermeable rock (limestone) Oldest rock layer
We can see that truly the clay is older than the sand and gravel according to Jenny.
The limestone is also older than loam according to Jack.

Disruption in the intercalated discs in the cardiac muscles would interfere with the hearts ability to beat in synchronous manner.
The important salient features of intercalated disc are-
- These intercalated disc in cardiac muscles of the heart create connections between nearby cells
- The intercalated disc provides for coordinated operation of the cardiac cells and is highly specialised to facilitate the beating
- Extensive folds and intercellular junctions for mechanical and electrical interactions between neighbouring cells make up the intercalated disc at the ends of muscle cells
The electrical characteristics of the cardiac muscle cells and the passage of electrical information from one region of the heart to another determine the rate at which the heart contracts and the synchronisation of atrial and ventricular contraction necessary for the efficient pumping of blood.

Answer:
Food provides the molecules that serve as fuel and building material for all organisms. Plants use the energy from light to make sugars from carbon dioxide and water. ... Organisms Explanation:
Answer;
C) It stores energy that comes from glucose.
Explanation;
-ATP is a biomolecule that is a product of cellular respiration which is used as a store of energy and is the usable form of energy by the cell.
-ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell.
-ATP is able to store and transport chemical energy within cells. Energy is released by hydrolysis of the third phosphate group.
The last one is correct lol
