Answer: The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds.
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
<em>A placental mammal develops before its body systems can function independently;</em>
A. Inside it's mothers body
<u>Mammals don't come from eggs, and the term placental mammal means it has a placenta. It comes out when our mothers deliver. A marsupial mammal forms in a pouch, so the answer is inside it's mothers body </u>
The term would be psychophysics
Psychophysics is a science branch that investigates the relationship between physical stimuli (in this case light stimuli) and the sensations and perceptions they produce (like perception of color). It represents the combination of psychological events (psycho-) and physical events (-physics) with the purpose of finding their quantitative relation. Measuring the stimulus parameters (such as amplitude and wavelength of light stimuli) it is possible to determine the minimum perceptible stimulus or the threshold stimulus.
