Natural selection affects allele frequency. If an allele confers a phenotype that enables an individual to better survive or have more offspring, the frequency of that allele will increase.
Identical body cells. Mitosis is when cells reproduce themselves, and meiosis is where reproductive cells are created. You can remember it like "my TOE is made by miTOsis"
<h2>Answer:</h2>
Soil bacteria are mainly involved in four steps in nitrogen cycle.
- Nitrogen fixation
- Nitrification
- Ammonification
- Denitrification
<h3>Explanation:</h3>
- First of all atmospheric nitrogen is fixed by soil bacteria (N2 to NH3/ NH4+, NO3-)
- Nitrification: The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria (NH3 to NO3-)
- When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH+4), a process called ammonification.
- Denitrification is the reduction of nitrates back into nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.
Answer:
Energy
Explanation:
carbohydrates in the food that we eat are digested and broken down into glucose before entering the bloodstream
If it is a red blood cell than the cell will shrivel because the water will dissolve out of the cell ( because more water flows out of the cell than back into the cell the cell Shrinks )
