hese are hints you have to match one on the options with what the hint is describing.

bonsium (bo): this element is important for bone strength, both for aliens and earthlings. it is a metal in group 2 of the periodic table and has 20 neutrons.
spriklium (sk): an atom of this element may have an actual mass of 70 amu with 39 neutrons.
alloyium (am): this is a relatively rare metal that is often used as a hardening agent in metal alloys/mixtures. it is the second lightest metal on the periodic table.
bananium (bn): this element has similar chemical properties to softium and metium, but is heavier than both.

answer options:
be
mg
ca
ar

Hi there!

Based off the actual elements on the periodic table that share similar properties, I believe these are your answers:

Be - Beriliyium - Alloyium

Mg - Magnesium - Bananium

Ca - Calcium - Bonsium

Ar - Argon - Spriklium

Hope this helps!

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
