Atoms are not drawn to scale. Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom. Methane (CH4), a common greenhouse gas, has five atoms, one of carbon (C) and four of hydrogen (H, see Fig.

Explanation:

1) Is imposible to determine an element from a simple drawing, more information is need or a higher level of details. Also, a "red blob of atoms" sounds like the  description of a molecule (a union of two or more atoms) that may or may not be formed by only one element.

2) There are 92 natural elements, the other ones are synthetic and/or radioactive. You can identify them in the periodic table because their molecular weights are between ( ).

3) False, a molecule is a particular arrangement of atoms that can be from one or more elements. An element is a particular arrangement of atomic particles (neutrons, protons and electrons.)

yawa3891 [41]

Explanation: Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring muscle fibers.
