Hello.
This statment is true.

Homeostasis is the ability of an organism to stabilise its internal body metabolism in response to changes in the external environment. The ability to carry out homeostasis provides an organism a lot of freedom from the dependence on the external environment. For example, reptiles are cold blooded animals. They require the heat of the sun for body metabolism. But in the absence of heat or in case of harsh winters, the reptiles will not be able to adjust to the temperature and as a result perish. Mammals are warm-blooded animals, being able to regulate their internal body temperature as and when necessary. Winters will affect the warm-blooded animals less because their body will increase in metabolism in response to cold temperatures to raise the internal body temperature. This is possible only through homeostasis.
The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Answer:
The correct answer is - 13.5 cm.
Explanation:
According to the details of the blocks, the number of blocks each week as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Adding total blocks would be :
2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks
Each block equals 5 mm of growth.
Then, 27 x 5 = 135 mm
135mm = 13.5 cm
Thus, the correct answer is : 13.5 cm
