Answer:
It causes oxygen depletion in the water
Explanation:
When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.
Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.
Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.
Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.
When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.
Answer:
M.E = 5880 J
Explanation:
Given data:
Mass = 60 Kg
Height = 10 m
Mechanical energy = ?
Solution:
Formula:
M.E = K.F + P.E
K.E = 1/2 × mv²
P.E = mgh
Diver is not moving so K.E will be zero.
M.E = mgh
M.E = 60 kg × 9.8 m/s² × 10 m
M.E = 5880 J ( j= kg m²/s²)
Photosynthesis is the process in which plants make their own food using light energy from sunlight in the leaves of the plants. The equation of photosynthesis states that the combination of carbon dioxide, water, and light energy produces a carbohydrate (glucose) and oxygen.
6CO2 + 6H2O +light energy = C6H12O6 + 6O2.
From the equation, six molecules of carbon dioxide and six molecules of water produces one molecule of glucose.
Therefore, 24 molecules of carbon dioxide and 24 molecules of water would produce or yield 4 molecules of glucose.
Answer: c. omnivorous (both meat from hunted large animals and plant foods).
Explanation:
The denture pattern of Australopithecians was like that of the modern humans but there were some specifications which suggests that these were omivorous. Like, the size of the teeth was large, molars were enormous and powerful. Their canines were small and their cheek teeth were larger than the modern humans. These characteristics suggests that they were capable of eating plant foods such as fruits, roots and also meat of other animals.
