The following four events occur during cell locomotion: Place them in the correct order. 1. The cell breaks its rear contacts with the substratum, retracting its trailing edge. 2. A part of the cell surface protrudes in the direction of cell movement. 3. Lower surface of cell protrusion attaches to substratum, forming temporary anchorage sites. 4. The bulk of the cell is pulled forward over adhesive contacts.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.

Ecology can best be described as the study of what

The law of states that traits are passed from parents to offspring independently of one another.. true or false
