Mold
Explanation:
A mold is a cavity that is left behind in the rock after an organism hard part has been dissolved. These are important fossils that useful in relative dating.
- Some hard parts of organism are preserved in form of molds in soft sediments.
- The outline and important details of the hard part is preserved when the mold dissolves away.
- Fossil molds are representative on the internal outline of the hard parts of organisms.
- They are usually recognized as a part of body fossil in a section.

Abiotic factors are the nonliving physical and chemical components of an ecosystem, while biotic factors are the living components of an ecosystem. Both types of factors affect reproduction and survival
The strength of the electric field is 5 N/C
Explanation:
The magnitude of the electric field produced by a single-point charge is given by:

where
is the Coulomb's constant
Q is the magnitude of the charge
r is the distance from the charge
In this problem, we have:
is the charge producing the field
r = 100 m is the distance from the charge at which we want to calculate the field
Substituting into the equation, we find the s trength of the electric field:

Answer:
C. Each capacitor carries the same amount of charge.
Explanation:
When two or more different capacitors are connected in series across a potential source, each capacitor carries the same amount of charge.
In a series connected capacitor, sane amount of charge flows through the capacitors while different potential difference is passed across them.
The capacitors have the same charge as the charge flowing out directly from the potential source called emf since the emf is the driving force of charge in a circuit.
