BASAL METAZOANS. A body plan, baupläne , ground plan, ground pattern , or bodyplan , is "an assemblage of morphological features shared among many members of a phylum-level group". Bauplan (pl. Baupläne ) The generalized body plan of an archetypal member of a major taxon. Look at 4 groups.

Simplest matter. The Periodic Table. Atomic structure. Define the following terms. proton neutron electron nucleus. Atomic structure. proton: ▪ a subatomic particle that is found in the nucleus of an atom ▪ it has a positive charge and a mass of 1 amu neutron:

Simplest Form. 1 ) List the factors for the numerator and the denominator 2 ) Circle the Greatest Common Factor (GCF) 3 ) Divide both the numerator and the denominator by the GCF (whatever you do to the top you must do to the bottom!). Example: 20/24.

Simplest Form. By Mr. Bales. Objective. By the end of this lesson, you will be able to write a fraction in simplest form.

Simplest Formula. Molecular formulas represent the number and kinds of atoms in a molecule. For example what is the molecular formula for this molecule if blue represents hydrogen and cyan represents carbon. C 2 H 6. Simplest Formula.

The Simplest Animals. Phylum Porifera. Invertebrates Animals without tissues (Sponges) All are aquatic and sessile (stay in one place) The body plan is asymmetrical Made of a loose arrangement of cells with no defined cell layer. Sponges!. Sponges.

Simplest formula calculations. Q- a compound is found to contain the following % by mass: 69.58% Ba, 6.090% C, 24.32% O. What is the simplest (i.e. empirical) formula?

Simplest Rollover ( nonJavaScript !). We’re going to change the image’s source when the event, “ onmouseover ” occurs: < img src = “pic.jpg” height = “250” width = “250” onmouseover = “ src = ‘pic2.jpg’”> Note the quotes!!

NHCH 3. NHCH 3. Br. Cl. Cl. The Simplest Case. all possible EAS sites may be equivalent. strongly activating. Br 2. acetic acid. 87%. CH 3. HNO 3. H 2 SO 4. C(CH 3 ) 3. When activating effects are similar. CH 3. substitution occurs ortho to the smaller group. NO 2. C(CH 3 ) 3.

Simplest (Empirical) Formula. Simplest integer ratio of the atoms in a compound Assume 100 g of compound, %element is then g element in sample g element x 1 mol element = mol element g element CHCl 3 10.061 g C x 1 mol C = 0.83765 mol C 12.011 g C
