Answer:
See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
Answer:
C
Explanation:
A is wrong: making lipids is the SMOOTH ER's job, not the rough er
B is wrong: protecting the nucleus is the nuclear membrane's job
D is wrong: Producing ATP is mainly the mitochondria's job
C is right because the ribosome's main job is making proteins, and those instructions come from the nucleus, so there needs to be a close access.
Plant cells have chloroplasts (containing chlorophyl) that help them make food. Animals are heterotrophs, which mean they depend on other organisms for food. Therefore, animal cells don’t have chloroplasts.
