Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
- Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.
- The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.

true
Explanation:
Green plants have the ability to make their own food. They do this with a process called photosynthesis, which uses chlorophyll. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide and water into glucose.
Catalysts are substances that cause a chemical reaction to occur in a different way than it would otherwise happen without that catalyst – a catalyst could cause a reaction to happen at a faster rate, or at a lower temperature, than would be possible without the catalyst.<span>
