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:
Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.
Explanation:
Answer:
It destroy both harmful and beneficial microbes.
Explanation:
If scientist added a chemical to destroy the arctic microbes, the beneficial as well as harmful microbes also eliminated from that area where chemical is applied. The removal of harmful microbes is a good thing but the removal of beneficial microbes brings instability in the environment. These beneficial microbes helps in the recycling of nutrients for the plants present there. So the negative effect of chemical is that it also effect the beneficial microbes which are necessary for the ecosystem.
Answer:
With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).
Explanation:
According to this question:-
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we gage the photosynthesis rate in hr.
