Why cutaneous is best method for amphibia?​

Biology
1 answer:
aleksandrvk [35]3 years ago
3 0

Answer:

In order for this gas transfer to take place, an amphibian’s skin is damp and often slimy. Although cutaneous respiration requires less energy than breathing via lungs or gills, it can only take place at a constant rate. Most amphibians have lungs to handle respiration at a greater rate when required.

bixtya [17]

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will  least likely be altered in the population I

Explanation:

Population I -

Total population - 670

Brown birds - 603

Red birds - 67

Population II

Total population - 100

Brown birds - 90

Red birds - 10

Population III

Total population - 30

Brown birds - 27

Red birds - 3

Frequency of red birds in population I

\frac{67}{670} = 0.1

Frequency of red birds in population II

\frac{10}{90} = 0.11

Frequency of red birds in population III

\frac{3}{30} = 0.1

Red allele frequency will be highest in population II and it will be equal to \sqrt{0.11} = 0.33 as compared to 0.31 in case of population I and III

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will  least likely be altered in the population that has highest  brown individual , i.e population I

What are the 2 major divisions in cell cycle?
Paul [167]
Interphase and Mitosis. Interphase is where the growth of the cell occurs, and it also tends to get various nutrients that it needs for growing. Mitosis is happens once the cell splits into two, and so on once the duplicated cells start to perform interphase once again.<span>distinct cells, often called "daughter cells".</span>
