Answer:
1. A producer is an organism that is capable of making its own food. For example, plants.
2. A consumer is an organism that cannot make its own food and hence fed on producers or other consumers. E.g humans
3. A predator-prey relationship is a relationship in which a predator organism eats a prey organism. For example, lion and zebra.
4. Symbiosis is a biological interaction between organisms of different species.
5. Parasitism is a biological interaction in which one organism gains benefit and harms the other organism.
6. Commensalism is a biological interaction in which one organism gains benefit whereas the other organism neither gets harmed nor gains any benefit.
7. Mutualism is a biological interaction in which both the organisms benefit from each other.
8. A niche is the role which an organism plays in a community or an ecosystem.
9. The three types of symbiosis are Parasitism, Commesalism and Mutualism.
Prophase I
The chromosomes condense, and the nuclear envelope breaks down & crossing-over occurs.
Metaphase I
Pairs of homologous chromosomes move to the equator of the cell.
Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.
Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.
Prophase II
A new spidle forms around the chromosomes.
Metaphase II
Chromosomes line up at the equator.
Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.
Telophase II and Cytokinesis
A nuclear envelope forms around each set of chromosomes & the cytoplasm divides.
In this scenario, Sarah is primarily ENCODING INFORMATION INTO HER MEMORY.
Encoding of information involves the process of putting a series of characters in a specialized format for storage or transmission. Sarah is storing the information she is acquiring from the book into her memory. <span />
Photosynthesis deals with plants that are a living being receiving energy from sunlight which is not living.
When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.
