The part of the river that would have animals with very muscular bodies and adaptations that survive in turbulent water is the transition zone.
The purity of the wavelength of a visual stimulus determines the perceived saturation, or richness, of the stimulus. Wavelength is the distance from the peak of one wave to the next. Stimulus is a change in the environment and the reaction of the organism to it is the response.
I am pretty sure it is Sexual selection.
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
<u>If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes</u> and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.
