Answer:
C. Chromosomes
Explanation:
During fertilization in sexual reproduction, the nucleus of the male sperm cell fuses with the nucleus of the female egg cell. Chromosomes from the sperm combine with chromosomes from the egg to give the new cell a unique genetic make-up.
Movement of surface currents
Explanation:
- Remote sensing is used to gather data regarding Land use-mapping, weather forecasting, environmental study, and resource exploration.
- In the case of ocean currents, only satellite remote sensors can determine ocean currents synoptically over coastal regions.
- SAR(Synthetic Aperture Radar) is also used to determine the ocean currents.
- The flow patterns of ocean currents are drafted with satellite infrared scanners.
- Usually, many oceanographers use Radio antenna and high-frequency "Radio detecting and Ranging" for measuring surface ocean currents.
Answer:
If the producers would be removed in the food web, then the whole ecosystem would fall down and die.
Explanation:
The reason why producers are important in a food chain is because they provide food for the herbivore animals, and then, the carnivore animals kill and eat the herbivore ones, and whatever is left, is eaten by the decomposers. So, if we remove the root of the tree (producers), then can the tree(rest of food web) survive? The simple answer is NO.
So, Hence, the ecosystem won't be able to last long, all animals will die.
