Answer:

50%

Explanation:

Given that the genotype of the pink-flowered parent plant is "Rr" and that of the red-flowered parent plant is "RR"; the cross between heterozygous pink and homozygous red-flowered snapdragon plants obtain progeny in the ratio of 1 red: 1 pink.

The genotype ratio for the progeny is= 1 RR (homozygous dominant) : 1 Rr (Heterozygous dominant).

How to zoos affect the nitrogen cycle
SpyIntel [72]
<span>As humans change the way we live on the planet, the way that nitrogen moves around the Earth also changes. Nitrogen atoms may seem small enough to be easily overlooked. We look right through the ones in the air, do we not? Yet recent changes in the nitrogen cycle are causing a very noticeable effect on natural environments and human health. Lakes are clogged with aquatic weeds. Dead zones have formed in areas of the oceans where animals can not survive. Air pollutants that contain nitrogen are decreasing air quality and greenhouse gases that contain nitrogen are becoming more common.</span>

Yes, that is true. However, a penis can temporarily enlarge from blood flow (an erection) or it can be surgically manipulated. Hope that helps!
