Answer:
c. One half as much.
Explanation:
The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that <u>reduces the number of chromosomes in half</u>, generating haploid daughter cells.

The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
Answer:
The correct answer is option C. "2+".
Explanation:
A common procedure to test for the presence of antigens is to perform an agglutination reaction by performing an antibody screen. In an agglutination reaction that is graded 2+ the red blood cells start to be broken and medium-sized agglutinates are formed. In this reaction no red blood cells are free, only agglutinates are seen at the bottom of the microtubes. The characteristics of the reaction herein described concur with an agglutination reaction that is graded 2+.
