In prophase I of meiosis, homologous chromosomes form tetrads.
Decomposers are essential in breaking down organic matter into useful ones. For the nitrogen cycle, they break down bodies of dead organisms turning it into ammonia. Also, some bacteria break down nitrates turning into nitrogen which goes back to air.
The answer is
Recombination is an exchange between homologous chromosomes (e.g. chr 1 from mom x chr 1 from dad). Since it usually happens during meiosis, these strands are later separated. Recombination can be unequal or equal, but it's usually equal, and unequal crossovers are generally quite small (but a common source of addition/deletion).
Reciprocal translocation refers to an exchange between different chromosomes (e.g. chr 1 x chr 2). It is considered a large scale mutation (resulting in a large addition to one chromosome, and a large deletion in another).
Answer:
D
Explanation:
A group or member of a species would overtime become differentiated from the original species that originate from if they occupy a different niche that has a different and unique environmental conditions. In an attempt to adopt to the condition of the new environment, they would develop specific features. For example, the honeycreepers having a bill that are well adapted to eat certain foods.
Therefore, the most likely conclusion the scientist would make is D.
