Planarians lack dedicated respiratory and circulatory systems because:.
Answer:
There is no need for a special circulatory system as a human has because the flatworm doesn't breathe with lungs and doesn't need to transport oxygen around its body. The flatworm simply diffuses oxygen via its skin. This occurs wherever it may need the oxygen.

Environmental resistance includes
biotic/abiotic factors that are
to life.
Answer:
The environmental resistance factors are all the factors or things that keep a population of the organisms from endlessly increasing i.e. keep a check on it. . They reduce the chances for reproduction, affect the health of organisms/individuals, and raise the death rate in the population.
The environmental resistance factors include the factors that are biotic and abiotic.
• The biotic factors are things like a predation, a parasitism, lack of food, competition with other organisms and disease.
• Abiotic factors include factors like drought, fire, temperature, and even the wrong amount of sunlight could affect it.

Which sustainable building practice does the photograph show?
A. Using a green roof to capture carbon and reduce a building's
energy costs
B. Reusing old bottles and cans as insulating building materials
C. Reducing fossil fuel consumption and its associated pollution
D. Replacing wilderness with buildings to reduce the absorption of
carbon dioxide
Reusing old bottles and cans as insulating building materials is the sustainable building practice. Therefore, option (C) is correct answer.
Sustainable building practices aim to minimize the environmental impact of construction and operation of buildings while enhancing the health, well-being, and productivity of occupants. These practices involve incorporating environmentally responsible methods and materials into the design, construction, and operation of buildings.
Therefore, reusing old bottles and cans as insulating building materials is the sustainable building practice.

and standard deviation of
1.00°C.
Assume
2.9%
of the thermometers are rejected because they have readings that are too high and another
2.9%
are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others.
So far The 2.5% extreme, we have to find the supposed to this area. It should be 2.5% of .0025. We have to find P 2.5 or mhm 97.25. This extreme, so for this boat, the extreme from that table, that value will be -1.96, And this value is 1.96. This is the right from that table, and this is the required answer.

The parents have the following alleles.
Bb
Bb
What color hair do the parents have?
A. One has blonde and the other has brown
B. Brown
C. Blonde
d. unable to determine
Given what we know, we can confirm that the parents have brown hair.
This has to do with how dominant alleles work. When an allele is dominant, it is because, in the presence of mixed alleles, this trait will always be the one reflected in the phenotype of the individual. Since the parents possess an allele for brown hair and one for blonde, but brown hair is dominant, both parents will have brown hair.
Therefore, we can confirm that both parents will have brown hair due to the dominant nature of the brown hair allele.
