Blubber is a thick layer of fat (adipose) tissue. Animals store extra digested food in the form of adipose tissue, which contains molecules called lipids.
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:
1- By eating a supplement that enhances the ability of red blood cells to transport oxygen, thereby reducing the oxygen dependence
2- By developing structures that help to support high pressures, thus improving the ability to breathe in deeper marine habitats
Explanation:
Recently, it has been shown that beneficial mutations provided to marine mammals a biological adaptation associated with a higher ability to transport oxygen in red blood cells when compared to terrestrial mammals. This adaptation enables marine mammals to breathe less frequently to obtain the same amount of oxygen.
In birds, the airflow is unidirectional (i.e., inhalation and exhalation are complete), rather than mammals where the air in and out of the lungs. This mode of respiration helps the birds to tolerate the high pressures during flight.
Answer:
- Dry climates do not have sufficient <u>moisture</u> during most of the year.
- Deserts are located in the <u>arid</u> climate.
- The <u>temperate</u> climate is in a grassland, or steppe, region.
Explanation:
Desert climate develop when the rate of evaporation is extremely higher than the rate of precipitation. This means that the moisture content would be very low in most of the times of the year. Hence, in the long run, the climate will become semi-arid to arid.
On the other hand, temperate climates reflects the conditons of moderate rainfall that spreads across the year or most time of the year. Usually, temperate climate has sporadic drought, mild to warm summers and cool to cold winters. These conditions are enough supporting to produce grasslands, or steppe.
