2c would be transcription because it is the first step in building proteins. and 3 would be translation because the information is being carried to mRNA
Answer:
a. The purple allele is lethal in the homozygous state
Explanation:
You cross a purple parrot with a true breeding (homozygous) white parrot and you get 1/2 purple parrots and 1/2 white parrots. This result can only happen if the purple parrot is heterozygous and the white parrot is homozygous recessive (if any of the parents had been homozygous dominant, 100% of the offspring would have had the dominant phenotype).
Then: Pp (purple) X pp (white) ---> 1/2 Pp, 1/2 pp
When you cross two purple parrots you get 1/3 white parrots and 2/3 purple parrots. The 2:1 phenotypic ratio is typical of a lethal allele in the homozygous state.
In a cross of two purple parrots: Pp
X Pp, one would expect the genotypic ratios 1 PP : 2 Pp : 1pp and the phenotypic ratios 3 Purple : 1 white.
But the PP genotype is lethal, so those individuals die and the only purple parrots we see are the heterozygous ones.
Answer:
8.Active Transport
9.phospholipid
10.facilitated diffusion
11.osmosis
12.ATP
Explanation:
Active transport is similar to osmosis but it happens with other substances
The phospholipid is shaped like a ball with two legs coming out and the legs connect on both sides of the cell to help protect the membrane and to help provide pathways.
Facilitated diffusion is just what is happening when the material or substance is going through the membrane which is either active or passive.
Osmosis is when the water passes through the membrane from a less concentrated place to a high concentrated place
ATP is energy used to help material or substance through the cell however only certain types of material need the energy to pass through some don't require energy at all
