Excreting urea helps in maintaining internal homeostasis by retaining water.
The mammals like humans excrete urea, while reptiles and birds, and some terrestrial invertebrates generate uric acid as waste. Generating uric acid in place of urea is beneficial as it is less toxic and diminishes water loss and the subsequent requirement for water.
This retention of water helps birds and reptiles to sustain internal homeostasis mainly in hot weather.

Answer:
The force of spring will be "3.75 N". The further explanation is given below.
Explanation:
The given values are:
Spring constant, K = 75.0 N/m
x₁ = 0.200 m
x₂ = 0.150 m
So that,
⇒ 
⇒ 
⇒ 
Now,
Force of spring will be:
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
The correct answer is:
D. It divides one diploid cell into four haploid cells.
Explanation:
Meiosis is a specific type of cell division that reduces the chromosome number by half, forming four haploid cells, each genetically different from the parent cell that yielded growth to them. Meiosis is a method where a single cell divides double to produce four cells comprising half the innovative amount of genetic information.
- Answer: Yes they are related
Explanation:Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
