These are true and false questions and i want to be sure of my answers. someone check. :
the eight-element periodicity found in the periodic table is related to the number of electrons in the outermost energy level of the atoms that make up each element. true
2. electrons in the first energy level of an atom are called valence electrons. false
3. for atoms important to life, if the first energy level is the outermost shell, it is stable with 2 electrons. if any other energy level is the outermost shell, it is stable with 8 electrons. true
4. atoms tend to react in ways that give each atom a stable outer shell of electrons. true
5. atoms with an outer shell that is almost empty are located on the right side of the periodic table while atoms with an outer shell that is full or almost full are located on the left side of the periodic table. false
6. atoms in the same row of the periodic table tend to have the same number of valence electrons. false
7. atoms with 7 valence electrons tend to be non-reactive. false

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

Fan egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, what is the result of this union? a) all future somatic cells of the organism will contain the (2n + 1) number of chromosomes. b) all future somatic cells of the organism will contain the (2n - 1) number of chromosomes. c) only certain somatic cells of the organism will contain the (2n + 1) number of chromosomes. d) all future somatic cells of the organism will contain the normal diploid number of chromosomes.

Iwanna go do something with my ideas? ?
