Answer:
the growth rate should be 20
Explanation:
Answer:A): four electron shells
Explanation:
In the period table, atoms are arranged in rows called periods and columns called groups. The arrangement of atoms in groups is based on the number of their valence electrons while the arrangement of atoms across the periods is based on their number of electrons shells. Atoms are arranged across the periods in increasing order of their atomic number i.e., according to their number of electrons. Potassium has 19 electrons while copper has 29 electrons. Both has four electrons shells according to their electronic configuration.
Answer:
Bacteria and fungi decay convert the dead remains of plants or animals or their waste products to ammonia (NH3). Nitrification: The ammonia is converted to nitrites and then to nitrates by nitrifying bacteria. Some of the nitrate formed in the soil is absorbed and assimilated by the plants.

Answer:
Please find the definition of viscosity, effect of heat on DNA explanation to this question below
Explanation:
Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.
DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
