A square pyramid is a pyramid whose base is in the shape of a square.
The Answer is isosahedron
A pentagon has 5 sides whose midpoints form a star shape.
Sometimes. A prism whose base is a n-sided polygon has the same number of vertices (2n) as a pyramid with a base that is a (2n-1)-sided polygon. For example, a triangular prism has the same number of vertices as a pentagonal pyramid.
A quadrilateral is a 4 sided shape whose 4 interior angles add up to 360 degrees.

A living organism is an organism whose parts are still functioning, a dead organism is an organism whose parts have ceased to function. All the materials are still there (unless something has been removed), it is simply the organization of said parts that has changed.
It is a living thing made of more then one cell.

A hexahedron is a 3D shape with 6 faces. It CAN be a prism whose base is a square. But that is only one example. It can also be a prism whose base is any quadrilateral. It can also be something like a pentagonal pyramid (i.e. the base is a pentagon and the sides are made up of 5 triangles.)
i think it's a cone * * * * * No, it cannot be a cone. But there are a number of possibilities: A decagonal pyramid = a pyramid whose base is a decagon. A nonagonal prism = a prism whose bases are nonagons. A pentagonal pyramid + pentagonal frustum = two pentagonal pyramids stuck together along their pentagonal bases and with one of the apices (plural of apex) cut off. A cuboid with three corners cut off. et cetera.
An organism whose tissues are completely replaced by minerals is a fossil.
An organism whose cels contain nuclei is called eukaryots!
Prokaryote
the cytoplasm
A simple organism without nucleus: an organism whose DNA is not contained within a nucleus
