Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets
Answer:
it must be translated into the encoded protein. ... Each group of three nucleotides encodes one amino acid. ... Three is the minimum number of nucleotides per codon needed to encode 20 ... of the genetic code allows one to predict the amino acid sequence of any ... Not all base subsitutions alter the encoded amino acids.
Explanation:
Metamorphic rocks are used in our everyday life. For example, the metamorphic rock slate is used for roof tiles as it resists acidic weathering. Also metamorphic slate/rocks are used for blackboards and jewelry.
Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.
Answer:
one that has an unstable nucleus
Explanation:
An isotope is defined as a chemical variant present in an atom with different number of neutron but same number of protons.
Radioactive decay is the sudden breakdown of an atomic nucleus allowing matter and radiation to be emitted from the nucleus. A radioisotope with unstable nuclei undergoes radioactive decay because they do not have adequate binding energy to keep the nucleus together. there are four types of Alpha, Beta, Gamma Decay and Positron Emission.
Hence, the correct option is "one that has an unstable nucleus"
