Answer:
a. Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.
Explanation:
The primary or main pigment in plants is the chlorophyll. The chlorophyll gives plants their characteristics green colour and helps in the absorption of light during photosynthesis.
Other pigments in plants include carotenoid with its characteristic yellow, red or orange colour; anthocyanin with its re/blue colour and betalains with its red/yellow colour.
<em>Hence, if pigments from a particular species of plant are extracted and subjected to paper chromatography, one would expect the pigments to be separated into several colour bands ranging from green to yellow/orange.</em>
The correct option is a.
Answer:
Competition occurs when two organisms fight over a resource that they need. It is a negative/negative reaction. They also compete for mates. If resources are scarce the two species will fight over the resources for their own survival.
Cells are the basic unit of life. Atoms make up molecules. molecules make up cells. cells make up tissues. tissues make up organs. organs make up organ systems and organ systems make up the human body. therefore, without cells, there is no life.
Answer:
Tolerance.
Explanation:
Ecological succession may be defined as the change of an species, its structure and change in the ecological community with time. Two main types of succession are primary succession and secondary succession.
The earlier plant stage does not affect the late successional plant stages. These two plant stages does not have direct competition, they are showing the tolerance model. The different species tolerate the different successional stages of each other.
