HELP!! RELATIVELY QUICKLY PLEASE!!
Daniel [21]
Okay, first the clear up. The Homozygous dominate trait is RR and is Red, the Heterozygous trait is Rr and is Pink, and the Homozygous recessive trait is rr and is white.


Part A: The co-dominance or incomplete dominance mixes the colours together, so the phenotype for the Heterozygous Rr flower is pink.


Part B: This question is easiest to explain with a punnet square... so. Diagram attached.

Part C: To get only Heterozygous genotypes, the gardener must cross only White flowers with red flowers. Because both these flowers are homozygous pairs, it means that any offspring created from that group would have a mix of the two. This is clearly seen in the F1 generation of Mendel's experiments for further proof. If any other pair is chosen ie Red with red: all red offspring, white and white, all white offspring. Pink and pink, a 1:2:! ratio. Red and Pink: 1:1 ratio of red and pink. White and pink: 1:1 ratio of pink and white. Red and white: Only pink offspring.

Hope that helps, message if you need it explained.

When does facilitated diffusion occur?
Trava [24]

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Suppose a large number of dead fish are found floating in a lake. how would you determine whether they died from cultural eutrop
Otrada [13]
To determine the reason for the fish death, do the following:
1. Test the water for the presence of organic substances that may be poisonous to the fish.
2. Test the dissolved oxygen concentration of the lake at different locations and at different depths. 
3. Perform full toxicological examination of the lake to determine if any pollutant or poisonous chemical is present in the lake.<span />

Rapid defibrillation is a link in the adult chain of survival. why is this important to survival
Marysya12 [62]
Rapid defibrillation is important because it contributes greatly to the survival of sudden cardiac arrest patients by eliminating abnormal hearth rhythm. Research has shown that the only proven, effective treatment for sudden heart attack is prompt defibrillation which is applied within the first few minutes of attack.
