Rays of light can travel through the cardboard when I hold my largest cardboard square between the light source and the wall, but because the cardboard is not very thick, the light can still pass through and create a shadow.

2b. The shadow is typically shorter.

2c. Completely no shadow 2d. The shadow is either clear or hardly there.

Do cardboard sheets block light?

Based on the precise materials and light sources that were employed, the results of the cardboard experiment frequently differ.

Keep in mind that it is generally expected that reflective materials, such as aluminum foil, and mirrors, would reflect the specified or given light.

Bones _____. Make blood cells are controlled by smooth muscles are part of the autonomic nervous system are connected to muscles
Alenkinab [10]

Answer:

make blood cells

Explanation:

<u>The red blood cells are made from the bone marrow of bones. </u>

<em>Smooth muscles form organs like the bladder and the stomach and allow them to change shape in order to perform their respective functions. Smooth muscles have nothing to do with bones.</em>

<em>The autonomic nervous system controls the functions of the body such as digestions, arousal, etc. It is a system of nerves, not bones.</em>

<em>Tendons connect muscles to bones, not synapses.</em>

Hence, the correct option is the bones make blood cells.
