It has been found that the rainforests are accountable for about one-third, that is, 28 percent of the oxygen of the Earth, however, the majority of the oxygen, that is, about 70 percent in the atmosphere is generated by the marine plants. The left-over two percent of the oxygen comes from other sources.
The majority of the oxygen comes from the tiny plants in the ocean known as phytoplankton, which lives near the surface of the water and drifts with the currents. Similarly to plants, they perform the process of photosynthesis, that is, they utilize carbon dioxide and sunlight to prepare food, oxygen is the by-product of photosynthesis.
However, the concentration of the dissolved oxygen, which the water can hold relies on the salinity and temperature of the water. The cold water can withhold more oxygen in comparison to warm water and fresh water can hold more oxygen in comparison to salt water. So, the warmer and saltier the water is, the less will be the oxygen dissolved in it.
If B and b are the two alleles , B + b = 1 and B ^2 +2 Bb + b ^2 = 1.
If 16% of mice are homozygous black , B ^ 2 =0 .16, meaning B = 0 .4 and b = 1 - 0. 4 = 0 .6 .
Answer = Notice how you don't even need to know that 24% of the mice are heterozygous .
Answer:
2. synthesize its own food
Explanation:
Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).
Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.
Greenhouse gas emissions will continue to increase in the short term, but as new technologies are discovered and implemented by governments and industries, this may eventually reverse. Global climate may continue to warm, but once greenhouse gas emissions are lowered, this may slowly reverse. Current solutions are not yet enough to stop the increase in temperature, but some technologies on the horizon are promising, such as carbon capture and storage, solar energy, and aquaculture of biofuels. One immediate way to reduce greenhouse gas emissions is a change in lifestyle, for example, using less fuel-intensive transportation options and saving electricity.
Well, as asexual reproduction suggets that offspring is genetically identical, you can assume that the "mother cell" qlso has 24 chromosones and thus may potentially have a genetic disorder
