Re: Muscle Tension

It should be isometric.

Isotonic muscle contraction remain constant provided that the weight of the object you lift remains the same.

While isometric contraction is characterize as contractions base on the sheer force and weight of different objects that was exerted with force.

Hope I helped.

Re: Homeostasis.

I think homeostasis is important because it helps humans slowly adjust to their environment.Without knowing for example the ideal body temperature, the body will exceed body enzymes and chemicals that may be harmful to the body. so its really very important. Hope I help..

you could both either be A or O. Genes in humans contain two alleles. One allele you get from mom, and one allele you get from dad. Alleles can be dominant (expressed when present), or recessive (only expressed in the absence of a dominant allele). A alleles are dominant over O alleles; O alleles ar...

Re: Stuck dessicator lid

You might try dripping a bit of machine oil into the seam so it can penetrate the grease. Having some shorter hydrocarbons diffused into the grease should loosen its grip. Let it penetrate for a few hours, the diffusion likely won't be fast though the grease. Hexane would be a reasonable alternativ...
