Cabulig River is bounded by Upper Jasaan and Bobontugan. The people will cross the river using bangka or bamboo boat. People living there make use of the river as their bathing area and for washing the clothes. The Table 1 shows the phytoplankton species per station in Cabulig River. With a population density of 583 species per millilitres‚ there were twenty (20) phytoplankton species found in Cabulig River. There are seven (7) orders in the class Bascillariophyceae. Three (3) of which belongs order

Photochemistry From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Illustration of the electromagnetic spectrum. Note the visible spectrum‚ as well as ultraviolet and infrared regions. Photochemistry‚ a sub-discipline of chemistry‚ is the study of the interactions between atoms‚ small molecules‚ and light (or electromagnetic radiation).[1] The pillars of photochemistry are UV/VIS spectroscopy‚ photochemical reactions in organic chemistry and photosynthesis in biochemistry

used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants‚ algae‚ and cyanobacteria‚ photosynthesis uses carbon dioxide and water‚ releasing oxygen as a waste product. Photosynthesis is vital for all aerobic life on Earth. In addition to maintaining normal levels of oxygen in the atmosphere‚ photosynthesis is the source of energy

Ch. 1 Questions 3.) How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts‚ huge volcanic eruptions‚ or great earthquakes? The principle of uniformitarianism states‚ “The present is the key to the past (Murck‚ B. W.‚ Skinner‚ B. J.‚ Mackenzie‚ D.‚ Visualizing Geology 2008). This means that anything that happens or will happen today‚ most likely has happened in the past. Scottish geologist James Hutton’s observation is that the physical

algae‚ prochlorobacteria‚ and cyanobacteria) have the form known as chlorophyll a. These organisms also contain other pigment molecules known as accessory pigments (see Table). Accessory pigments absorb energy not absorbed by chlorophyll a. Chlorophyll b‚ xanthocyanin (a reddish pigment found in coleus leaves)‚ and beta-carotene (the yellow-colored pigment found in carrots) are examples of accessory pigments.

What chemical associated with the cell wall gives Gram-positive bacteria their final color? Peptidoglycan 3. a. In what ways are cyanobacteria like algae and land plants? They go through the photosynthesis b. How are they different? They are prokaryotes

Changes in the Atmosphere Causing Multicellularity About 2.5 billion years ago‚ oxygen began slowly to accumulate in the atmosphere‚ as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage‚ and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic bacteria. Other cells may have become symbionts with larger cells and evolved into mitochondria

The human body is its own natural defense system‚ and it will attack anything that threatens its homeostatic environment. If a slight cut in the skin breaks the barrier‚ it causes the
