Genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is typeAB.
If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents.
So the chance of alleles OO is 25% × 25% = 6.25%,
alleles AA is 75% × 75% = 56.25%,
alleles AO is 75% × 25% = 18.75%,
alleles OA is 25% × 75% = 18.75%.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A.
The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.

The correct answer should be Sensory Neurons, also known as afferent neurons. They <span>transport information to the integrating center.</span>
Answer: Lysosomes
Explanation:
Lysosomes is the type of organelles which contain enzymes that breaks down the various fatty acids. As, these enzymes basically work in the less oxygen areas and the low PH region. The peroxisomes absorbed all the nutrient from the cell and they are degraded from the sub-cellular structure.
The lysosomes is the single membrane that contain the digestive enzymes for breaking all the toxic material such as fatty acids, ethanol and hydrogen peroxide in cells.
C. The nuclear envelope contains the nucleus and forms a barrier between it and the cytoplasm
