Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
Answer: pH 5 Acidic environment.
Explanation:
The fungi grows best in the acidic environment, this is because the fungi grows in a moist, warm and darker environment.
The fungus grows at lower pH. When the fungal species was grown in the laboratory conditions then under low pH, the fungal species grow more properly.
Hence, the best environment for the growth of fungus is pH 5.
Answer:
B
Explanation:
I'm pretty sure that's the answer because the others seem very odd for a population scale when a new pipe is inserted.
Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
Answer:
No, If that was the case, then we should only be eating carbohydrates.
