If an organism urins little or no at all, then the organism may live in . Single Choice .

Reason for choosing B: If you don't urinate, you lose very little water, so your water intake is also very small, so you can maintain the water balance in your body. This is a manifestation of biological adaptation to the environment, the result of long-term evolution.

Deserts are extremely short of water, so they can't lose a lot of water, otherwise organisms will die due to extreme lack of water in their bodies.

Isn't it a cold zone? Doesn't urinating take away the heat? Hey!

b Desert area.

This is the ability of desert organisms to survive and evolve in a long-term arid environment, because the intake of water in the desert is very limited, so the organisms living here must learn to retain water, and if they urinate too much, the organisms will be dehydrated and die due to a large amount of water loss.

b.Desert terrain.

I'm guessing you're talking about being homeothermics (which might be a fitting title), and ectotherms produce a lot of water and nitrogenous waste by breathing and feeding their body temperature to keep their body temperature constant. If the ambient temperature is high, the metabolism of the new city to maintain a constant body temperature will be less, so the amount of urine will be relatively less.

B, lack of water in arid areas, biological nitrogen excretion is mainly discharged in the form of uric acid, 1 molecule of uric acid nitrogen content is 2 times that of urea, insoluble in water and non-toxic, can be highly concentrated in a thick paste discharge, so you can urinate less or no urine, such as Greek tortoises, lizards, flower snakes, etc. in the desert.

The various factors that affect the life of organisms in the environment are called environmental factors, which are divided into abiotic factors and biological factors Abiotic factors include: light, temperature, water, air, soil, etc. Biological factors refer to other organisms in the environment that affect the life of a certain organism, including organisms of the same species and different species Desert drought and water shortage, and water is the main component of organisms, water affects the growth and development of organisms, and determines the distribution of terrestrial organisms The serious lack of water in the desert leads to the scarcity of biological species in desert areas and the amount of urine of organisms is small, do not sweat, then this organism is suitable for this lack of water living environment and A, C, D environment, relatively speaking, water is more

Therefore, b
