CITES work by subjecting international trade though Licensing System.
<u>Explanation:</u>
Approximately, 30000 species of Plant and 5800 animal species are under Protection by CITES against over exploitation through international trade. Flora and Fauna species are grouped in three appendices depending on how much they are threatened by International trade. CITES works by subjecting. To certain control, CITES used to subject international trade of specimen of certain species. There are applicable licensing system which is controlled or monitored by management authorities and scientific authorities. Role of Scientific authorities to advise effect of trade on species status.
All Export, Import, re export of these species should be authorized by Licensing system
Appendix I species are endanger of extinction and their trade permitted on exceptional situation.
Appendix II species are not in endanger of extinction but their trade need to be controlled to avoid species utilization that are unsuited with their survival
Appendix III contain those species which are endangered in at least one country and these are asked with CITES parties for helping in controlling their trade
B
<u>Temperature</u> is NOT a density-dependent factor affecting population growth
Explanation:
Density-dependent factors mean variables that are affected by the density of the population. The opposite of density-depend is density-independent factors. These are those variables that affect the density of the population but are not affected by the density of the population.
In this case, temperatures are not affected by the density of the population. However, temperatures affect the density of the population. Most individuals can only survive within an optimal temperature range.
The rest of the choices are density-dependent variables

Answer:
3, 1, 4, 2
Explanation:
The effects described are called phototropism, where light affects the direction of growth of the plant.
Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.
Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.
This causes the plant to bend towards the light.
En la respiración celular, la célula depende totalmente de las reacciones Redox, para ser precisos de la reducción del NAD a NADH y la oxidación de NADH a NAD.
Ahora veamos una situación diferente.
En la fotosíntesis, ocurre la reacción inversa de redox, como se muestra en la siguiente ecuación:
6CO2 + 6H2O + E --> C6H12O6 + 6O2
La energía biológica se almacena y se lanza con la frecuencia por medio de reacciones redox. La fotosíntesis implica la reducción del CO2 en azucares y la oxidación del H2O en oxigeno molecular (O2), mientras que en la respiración es lo inverso, la oxidación de azucares a CO2 y H2O.
Entre los pasos redox de la fotosíntesis, compuestos deducidos del CO2 reducen el NAD lo que crea entonces, la creación gradiente de protones, que conduce a la síntesis del ATP y es mantenida por la oxidación del O2.
En los seres vivos, el término redox se utiliza para describir el equilibrio NAD-NADH y NADP-NADPH.
El estado redox contribuye al equilibrio de los sistemas metabólicos. En el caso de alteraciones en las reacciones redox, puede producirse HIPOXIA, que es el déficit del O2 en la sangre, CHOQUE, que es el mal circulamiento de lal sangre y la SEPSIS.
