Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which saves water.
Nitrogenous waste in the body tend to form toxic ammonia, which must be excreted. Mammals such as human excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste in the form of a white paste or power. The production of uric acid involves a complex metabolic pathway that is energetically costly in comparison to processing of other nitrogenous wastes such as urea or ammonia, it has the advantages of reducing water loss and, hence, reducing the need for water.
Answer:
homeostasis
Explanation:
Homeostasis has to do with processes that maintain the internal balance within an organism. It can succinctly be defined as the process of regulating an organism's internal environment. The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.
Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.
All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.
H1
one proton
one electron
zero neutrons
H2
one proton
one electron
one neutron
H3
one proton
one electron
two neutron
Answer:
cDNA library.
Explanation:
Genomic library may be defined as the collection of all the genomic DNA of an individual. The genomic library is constructed by the digestion of digestion of DNA fragments and there further transfer in the vectors.
cDNA library is prepared in case of eukaryotes because the complementary DNA is produced from the RNA. The eukaryotes DNA is interrupted with exons. In case of spider, the cDNA linrary is prepared because its DNA is interrupted with exons.
Thus, the answer is cDNA library.
Answer:
1. ____TRUE_______each strand of DNA in the duplicated chromosome is referred as the centrioles? 2.______TRUE_____ cytokinesis begins the process of cell division?
