Soloha48 [4]

Hello. You forgot to add the diagram required to answer that question.

The diagram can be seen in the figure attached below.

Answer:

According to the diagram, James Carnegie and Czar Nicholas II are third cousins. On the other hand, Tsar Nicholas II was the great-uncle of Countess Xenia.

Explanation:

The figure below shows the genealogical diagram that allows us to see the degrees of relationship between the generations of a family.

At the beginning of the tree we can see at the beginning of the diagram that the marriage between Louise of Hess Castell and King Christian IX of Denmark generated daughters Alexandra and Maria.

Alexandra had a daughter named Louise and Maria had two children, Nicholas II and Princess Xenia.

With that, we can say that Louise was a first cousin of Nicholas II and Princess Xenia.

With that, we can say that Louise was a first cousin of Nicholas II and Princess Xenia.

Louise had a daughter named Maud (who is a second cousin of Nicholas II and Princess Xenia) and later had a son named James Carnegie, who was a third cousin of Nicholas II and Princess Xenia.

Pricess Xenia, Nicholas II's sister, had a daughter named Irina (who was Nicholas II's niece). Irina had another daughter, named Irina (who was the granddaughter of Princess Xenia, making Nicholas II her grandfather) who later had a daughter named Countess Xenia (who was the great-granddaughter of Princess Xenia, and therefore Nicholas II was her great-uncle) .

a student exposed two plants to only red light and two plants to only green light. which plants should grow faster and why?
uranmaximum [27]
The plants exposed to green light will be more likely to grow faster, since, the green plants' cells go through something called photo- synthesis, and that creates a green hue in the plant's color.( most plants) So when green matches with green, the process speeds up.
