Santa= AA
Mrs Claus= aa
-----------------------
PARIENTAL: AA x aa
Gamets: A A x a a
F1: Aa ,Aa,Aa,Aa -100% good vision
Pariental 2: Aa x Aa
Gamets: A a x A a
F2: AA Aa Aa aa so we have here 75% good vision,25% bad vision which is 3:1
and we have 1 dominant homozygous,2 dominant heterozygous and 1 recessive homozygous,which is 1:2:1.
Facilitated diffusion
i also included a photo of the explanation of facilitated diffusion. i hope this is helpful
MRNA: AUG AAU UUA GCG ACA
polypeptides: Met or start, Aan, Leu, Ala, Thr
1. The type of mutation that occurred in this strand of DNA is deletion. This may have happened because a small part of the DNA sequence was lost when broken ends were rejoined when the DNA was being repaired.
2. It is not likely that these mutated genes could produce a working protein because the polypeptides were completely changed, which would cause the protein to not work properly.
3. When a seed first absorbs water, it begins to grow. The mutation could cause the plant to be unable to absorb water. Therefore, the plant would be unable to germinate.
Answer:
The correct answer is option - C amino acids.
Explanation:
The blood brain barrier or BBB is border that separates extracellular fluid in the central nervous system (CNS) and the blood that is circulating from the brain.
This barrier is allows the passage by facilitate diffusion (passive diffusion) and through the selective proteins of molecules such as glucose, amino acids that are essential for the neural function.
Thus, the correct answer is - amino acids.
