Question | Answer |
Bryophytes | Nonvascular plants are known as bryophytes (mosses). They lack tissue that will conduct water or food. |
Flowering plants | Angiosperms are those plants that produce flowers as reproductive organs. |
Shoots and roots | Angiosperms (flowering plants) have two main systems—the shoot system, which is mainly above ground, and the root system below ground. |
Produce seeds without flowers | Gymnosperms produce seeds without flowers. |
Conifers and cycads | Gymnosperms produce seeds without flowers, which include conifers (cone-bearers) and cycads. |
An athlete with a sore shoulder places a warm compress on it to transfer energy to soothe the muscle. | An athlete with a sore shoulder places a warm compress on it to transfer energy to soothe the muscle. |
On a cold February morning, a blower system in a car warms up after several minutes and blows air through vents in the floor, dashboard, and windshield. | Convection is caused by the flow of heated liquid or gas through a volumetric medium. |
Getting ready for a fall cruise inspires a young lady to spend a couple of weeks going to a local spa and reclining under a tanning lamp. | Radiation is waves traveling through space to transfer heat away from the energy source. |
This substance is a very strong oxidizing agent. | The manganese ion in potassium permanganate has a +5 oxidation state, and is therefore readily reduced. When it is reduced, it forces another species to be oxidized. Therefore, the permanganate ion is a very strong oxidizing agent. |
The metal in this substance has an oxidation number of +2. | The magnesium atom that is combined with oxygen has a +2 oxidation state. Oxygen carries a –2 oxidation state, and the sum of the oxidation states of oxygen and magnesium must total the charge on the compound, which is 0. |
The oxidation potential of this substance is zero. | Hydrogen gas by definition, since it is a standard, has an oxidation potential of 0. |
Exponential population growth curve; population growth accelerates | One of the modes of population growth is represented by the exponential curve (or J-curve). The rate of growth accelerates over time since there are no limiters of growth. |
Birth rate minus death rate | The rate of increase within a population is represented by the birth rate minus the death rate. |
Death rate | Mortality is the death rate within a population. |
Birth rate | Natality is the birth rate within a population. |
Logistic population growth curve; population growth accelerates and then slows down because of limits | Another mode of population growth is represented by the logistic curve (or S-curve) for populations that encounter limiting factors in which acceleration occurs up to a point and then slows down. |
