The Archaebacteria are the most primitive bacteria that defines the limits of life.

Members of this archaea include the bacteria that can survive in the temperature range of 113 °C and found living in hydrothermal vent.

Example: Pyrolobus fumarii

Some of the Archaebacteria were found in the most acidic conditions (soil) that were known to grown at the pH of 0 and were known as methanogens.

These bacteria were capable of producing methane gas in hot spring and marshes, et cetera.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith

Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.

Alecsey [184]

The different degrees of sleep and wakefulness through which newborns cycle, ranging from deep sleep to great agitation, are called states of arousal. These states are regular sleep, irregular sleep, drowsiness, quiet alertness and crying. About eight to nine hours each of an infant's day is dedicated to regular and irregular sleep. So, most of the time of the infant is spent in these states. These are the states where the brain of an infant is developing the important connections for growth and survival. Crying is the means for infants to communicate their needs. Different type of cries would represent different needs of the infant.
