Answer: In an ionic bond the valence electrons are transferred from the metal only to the neighboring nonmetal, but in metallic bonding the valence electrons of each atom/ion are free to move or float around within the entire metal solid.
Explanation:
Answer:
pioneer species
Explanation:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support plants.
Answer:
Thermometers
A thermometer (thermos: hot; metron: measure) is the universal instrument used to measure temperature.
A clinical Thermometer is meant for clinical purposes. It is developed for measuring the human body temperature.
A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.
Similarities between Clinical Thermometer and a laboratory thermometer
Both are made of glass and consist of a long narrow glass tube.
At one end, both of them have a bulb.
Bulbs of both the thermometers consist of mercury
Celsius scale is present in both the thermometer
Answer:
The correct answer is "mutations to homologous genes".
Explanation:
The missing options of this question are:
A) morphology.
B) the pattern of embryological development.
C) biochemical pathways.
D) habitat and lifestyle choices.
E) mutations to homologous genes.
The correct answer is option E) "mutations to homologous genes".
Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
