Two identical copies formed by the replication of a single chromosomes
Answer:
Nuclear decay rates are constant
Explanation:
Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.
Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.
The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).
nebular hypothesis
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
Answer:
Global climate change affects the distribution of species.
Explanation:
Answer: ribozomes consist of enzymes needed for protein photo sythesis transfer rna trna brings amino acids to the ribosomes where the amino acids are signed up with like a string of beads to form a protein there is a various trna for carrying each type of 20 amino acids utilized to construct proteins
