Hi!
I would say C, weak, dead, or partial antigens because do you need to be introduced to the disease for your body to fight it.
Hope this helps!
Answer:
d. Meiosis II in the father
Explanation:
Since the son has two extra Y chromosomes, the nondisjunction would have occurred in father because females do not have Y chromosome. Before Meiosis DNA replication occurs during which the homologous chromosomes are replicated. During Meiosis I crossing over occurs and homologous chromosomes separate from each other. During Meiosis II sister chromatids of a chromosome separate and move into individual daughter cells.
Here, during Meiosis II the sister chromatids of Y chromosome did not separate from each other (nondisjunction). They collectively moved to one daughter cell. As a result one daughter cell had two Y chromosomes and other daughter cell had none. When the daughter cell containing two Y chromosomes combined with the daughter cell containing one X chromosome from mother, XYY individual was born.
Why do photosynthesis and respiration have such a great relationship?
<h3><u>Solution;</u></h3>
→ Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration.
→ Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis.
• Photosynthesis and respiration are both part of a mutually beneficial relationship.
I Hope you can understand :)
