Peritrichous refers to the bacteria having flagella all over the surface of the bacteria. The monotrichous bacteria have only one flagella. The phototaxis refers to the movement of the bacteria towards and away from the light. The movement of bacteria towards or away from a chemical stimulus is referred as chemotaxis.
Explanation:
Ciclo del Carbono
Un 18% de la materia orgánica viva está constituida por carbono, la capacidad de dichos átomos de unirse unos con otros proporciona la base de la diversidad molecular así como el tamaño molecular. Por tanto el carbono es un elemento esencial en todos los seres vivientes.
A parte de la materia orgánica, el carbono se combina con el oxígeno para formar monóxido de carbono (CO), dióxido de carbono (CO2), también forma sales como el carbonato de sodio (Na2CO3), carbonato cálcico (en rocas carbonatadas, como calizas y estructuras de corales).
18% of living organic matter is made up of carbon, the ability of these atoms to bond with each other provides the basis for molecular diversity as well as molecular size. Therefore carbon is an essential element in all living beings.
Apart from organic matter, carbon combines with oxygen to form carbon monoxide (CO), carbon dioxide (CO2), it also forms salts such as sodium carbonate (Na2CO3), calcium carbonate (in carbonate rocks, such as limestone and coral structures).

Answer: secondary succession
Explanation: An ecological succession can be defined as a change that occur in the biotic community of the ecosystem with respect to the changes that occur in the abiotic factors like water, soil and climatic conditions with respect to time.
Secondary succession can be defined as the changes that occur in an area which was previously occupied by the living species and the area was disturbed by either human intervention or natural calamity.
Brazil clear cut is an example of secondary succession because after the clear cut some precursors like seeds, roots and other parts of the plants or trees can support the regrowth of plants and trees. Initiating the succession again.
Researchers can examine the biological basis of fear, smell, memory, and diseases by using the following techniques:
1. The Role of Pro-inflammatory Cytokines in Memory Processes and Neural Plasticity.
2. Memory Systems.
3. The Memory Network.
4. Psychological and Neural Aspects.
