The best answer is B.
The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells:
1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell.
2. Both organelles use their DNA for to produce many proteins and enzymes required for function.
3. They are both surrounded by a double membrane.
4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
I think the correct answer from the choices listed above is option C/ One reason that a product does not always form is due to unfavorable geometry of the reactants involved. When the geometry is not good for substances to react then no reaction can occur although there is enough energy present.
Sorry i need pointsss the answer is nasal passages yeah
Answer:
9/256
Explanation:
According to Mendel's experiments the results for the heterozygous are in the ratio 3:1
As each gene is considered separately and the multiplication rule is used. Therefore the probability of getting a solid color would be 1/4 and black fur would be 3/4. Similarly the probability of getting the colored fur is 3/4 and getting a piebald( white patches) is 1/4
Then the combined probability is (1/4*3/4*1/4*3/4)= 9/256
