Answer:
1) Wax belong to lipids.
2) <u>Animals</u>: Water and cold isolation and protection from pathogenic microorganisms.
<u>Plants</u>: It controls evaporation and maintains hydration.
Explanation:
1) Wax belong to the biomolecules of lipids.
2) In animals, such as birds, the uropygial gland secrets sebum or wax, spreading it throughout the animal's feathers to prevent water from penetrating as it serves as an isolating compound for animals that live in cold areas. It also provides protection from bacteria and fungi. In coloquial terms, it would be like a water-proof coat that protects them from water and extreme climate.
In plants, the secretion of wax through the cuticle has been developed as an adaptation to control evaporation and maintain hydration.
Answer:
(B) open stomata only at night, limiting water loss because of heat and low humidity.
Explanation:
CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.
They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.
During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
Answer:
I would expect that the sample has only 50% of the original 235 U.
Explanation:
That is because 235 U has a half-life of 700 million years and I expect that my sample be 350 million years old. 350 is half of 700.
This scientific law is called as Law of conservation of energy.
Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.
Answer:
Explanation:
Ok so the change of the state is gas because u are boiling water so the water get hotter and then gas starts to come out of the water because of how hot it is
