Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
Van der Waals interactions may result when electrons are not symmetrically distributed in a molecule. Van der Waals forces, in physical chemistry are essentially
associated with the name of a Dutch researcher Johannes Diderik van der Waals
and indicate the separation of dependent interactions among particles and
atoms.
Answer:
Pentanol, glucose and fatty acid.
Explanation:
Pentanol, glucose and fatty acid are the three molecules which are present in the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.
Answer is stretch receptors.
Stretch receptors respond to the distention of muscle wall of the bladder and are neurologically linked to the medulla. Stretch receptors in the bladder signal the parasympathetic nervous system to stimulate muscarine receptors, present in the detrusor muscle, to make him contract. This leads to the expulsion of urine.
The answer is ureteral orifices.
Hope it helps!
