Answer:
D. competition
Explanation:
Both the owl and the raccon share a common prey, the mouse. They are both competeing for the food.
The human genome has been estimated to have 20,000 - 25,000 human protein - coding genes.
Before it was thought that the number of genes in the human genome was about 100,000, but with better and more advanced gene finding technology, this number has been revised down to the current estimate, and could continue to drop further.
The human genome has 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs.
Cells maintain homeostasis by consistently developing energy. Without energy, cells would fall into disorganized, unorderly processes and eventually cell death would occur. Cells also maintain homeostasis through diffusion and the plasma membrane, but regulating substances that enter and leave the cell.
The human body maintains homeostasis through body temperature, hydration, and food intake
Answer:
This question lacks options, the options are:
A. Concentration of carbon dioxide in the air
B. Quality of nitrates in the soil
C. Wavelengths of light
D. Availability of water in the soil
The answer is B
Explanation:
Photosynthesis is the process whereby cells of autotrophic organisms manufacture their food in the presence of sunlight. The rate at which the process of photosynthesis occurs, however, is dependent upon certain factors including the concentration of reactants (water and carbon dioxide), availability of light source etc.
Among the options, the concentration/availability of light, carbon dioxide and water, which are key reactants of photosynthesis, will have greater effect on the rate at which the process occurs than the availability of nutrients (nitrates) in the soil. Hence, the quality of nitrates in the soil will have the LEAST effect upon the rate of photosynthesis in a geranium plant.
Answer:
The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.
Explanation:
Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.
The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.
Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
