Answer: One strand of DNA binds to another via base complementarity.
Explanation:
The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.
The advantage is that the animals with bilateral symmetry can find food and mates and also avoid predators because they have sensory organs and good muscle control. An example of such animals would be human beings. Additionally, bilaterally symmetric animals have sensory organs focused at the head which interacts with the environment before the rest of the body does, which allows quick reaction and ability to be motile.
Answer: Option A.
6O2+6C6H12O6=6CO2+6H2O + energy.
Explanation:
Cellular respiration is a set of metabolic processes that occur in a living cells in which glucose is broken down in the presence of oxygen to produce energy(ATP) and release waste products.
The equation is O2+ C6H12O6=6Co2 +6H2O + Energy.
Answer:
urea
Explanation:
Excreta is the biological name used for nitrogenous residues produced by metabolism and should be eliminated in order to allow a state of internal equilibrium (homeostasis) of the organism, being the types of excreta in different groups of animals. These groups are divided between animals that accumulate ammonia, urea or uric acid prior to the release of nitrogen residues.
The human being is a ureotelic animal, that is, an animal that accumulates urea before excreting nitrogen waste.
Urea is a water-soluble substance, but less toxic than ammonia. Synthesized in the vertebrate liver from the reaction of ammonia and carbon dioxide, it represents an adaptive strategy of certain land animals: annelids, cartilage fish, amphibians, and mammals.
