How are cardiac muscle, smooth muscle, skeletal muscle alike?

They are alike because they perform Voluntary and Involuntary Controls.

Explanation:

1). Skeletal muscle: The skeletal muscle brings about movement by pulling on the skeletal parts of which they are attached. This is the type of movement that is responsible for locomotion.

2). Smooth Muscle: This muscle is composed of elongated spindle-shaped cells which are grouped into bundles or sheets. They are least specialized muscle cells and are under the control of the autonomic nervous system.

3). Cardiac muscle: This muscle is only found in the walls of the heart. The muscle cells are branched and connected to one another by special discs. These cells helps the cells to contract and relax in unison so that the heart can pump rhythmically.

hello there the answer is d

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
