Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll.
Answer:
Over time, many species gradually adapted to a more oxygen-rich enviroment, allowing them to survive in shallow water and on land.
A male and female of the same type reproducing makes a species?
Answer:
Forestry and hydrology studies have concluded that forest loss decreases the amount of precipitation that infiltrates the soil and increases the runoff volumes of streams and rivers. However, these findings do not reflect how the increase in runoff due to deforestation affects human access to clean water.
Answer:
1. Meiosis I
2. Tetrad
3. Tetrad
Explanation:
Crossing over refers to an event taking place in the cells undergoing meiosis cell division during which the exchange of material takes place. The process of crossing over takes place during pachytene of prophase I in meiosis I.
Crossing over takes place when the structure formed by the pairing of the four chromatids of the chromosomes called tetrad is formed. The formation of tetrad allows the exchange of genetic sequences, therefore, result in recombination.
The process of crossing over does not take place in the mitosis as the tetrad is not formed in the mitosis.
Thus, Meiosis I, Tetrad and tetrad are correct.
