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 2nd Table
Explanation:
DNA Polymerase is used in DNA replication and attaches Adenine to Thymine and Cytosine to Guarine (Remember it is always A to T and C to G). The 3rd table would be incorrect because cytosine doesn't attach to thymine. The 1st table would be incorrect because Uracil is used in RNA replication, not DNA replication.
For an endergonic reaction, the statement ΔG is positive is
the true statement. So the first option in the given question is the correct
option. Any reaction that requires energy to be absorbed is called an
endergonic reaction. For example, photosynthesis is a great example of
endergonic reaction. In photosynthesis sunlight is required to be absorbed to
complete the reaction. The sunlight acts as the energy required. This type of
reaction is never spontaneous, but requires external force to complete the reaction.
Answer: some moons are farther away and harder to spot
Explanation:
22% cytosine, because each pair has an equal amount of complementary base percentages. For example, if you are given 20% Adenine, then there has to be 20% Thymine as well, and you can also calculate cytosine and guanine by looking at the remaining percentage (80%). Because 80% is left over and each complementary base pair has equal amounts of base percentages, Cytosine and Guanine would each have 40%.
