Answer:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Explanation:

This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.

According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Of the more than 70 different ions that are dissolved in seawater the two most abundant _________.

valina [46]

The most abundant compound that can be found in the sea apart from water is the sodium chloride (NaCl). This is why we are able to retrieve table salt, which also comes in the same formula, from the sea. When sodium chloride dissociates into its ions, the two ions would be Na+ and Cl- which are called sodium ion and chloride.

Blood vessels traveling within the ________ space deliver oxygen and nutrients to the spinal cord

garri49 [273]

Answer: Subarachnoid

Explanation:

The space in the meninges below the arachnoid membrane and above the pia mater contains the cerebrospinal fluid. Cerebrospinal fluid is produced by choriod plexus( a cluster of capillaries) from the blood. Blood vessels traveling within the subarachnoid space deliver oxygen and nutrients to the spinal cord.
