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.

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) .

Vestigial structures are parts of an animal's body that serve no function, but did in earlier evolutionary stages. Two examples of this are the human appendix and the snake pelvic bone.

In a population of lizards, the allele that causes red eyes (R) is dominant, while the allele that causes green eyes is recessiv

zhenek [66]

The answer is 0.47 or 47%.

Let's first distinguish some terms and their frequencies.
R - the dominant allele that causes red eyes
r - the recessive allele that causes green eyes

Since R is dominant over r, lizards with at least one dominant R allele will have red eyes. Therefore, the genotypes and the phenotypes are as following:
genotypes - phenotypes
RR - the lizards with red eyes
Rr - the lizards with red eyes
rr - the lizards with green eyes

Now, we will use some Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1

where:
p - the frequency of dominant allele R
q - the frequency of recessive allele r
p² - the frequency of lizards with genotype RR
2pq - the frequency of lizards with genotype Rr
q² - the frequency of lizards with genotype <span>rr
</span>
We are interested in <span>the frequency p of the dominant R allele.
</span>So, we have the frequency (72%) of the lizards that have red eyes. However, lizards with genotypes RR and Rr will have red eyes. Since their frequencies are p² and 2pq, respectively, we have:
p² and 2pq = 72% = 72/100 = 0.72

Now, use this in the equation p² + 2pq + q² = 1:
0.72 + q² = 1
q² = 1 - 0.72 = 0.28

From here, we will calculate q and later p using the formula p + q = 1:
q² = 0.28
q = √0.28 = 0.53

p + q = 1
p + 0.53 = 1
p = 1 - 0.53
p = 0.47

Cell specialization is important during the growth and development of

Likurg_2 [28]

Answer:

Protein

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.

Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.

Simply stated, it's the special function or job in the body of a living organism that are associated with cells.

Generally, cell specialization plays a significant role in the development of embryos.

Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cell specialization is fundamental and key for the growth and development of a multicellular organism.

Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.

A cell that consists of a 65% salt concentration is placed in a solution with a 27% salt concentration. What will happen to this

zzz [600]

Answer:

The correct answer would be - the cell will get water and expand.

Explanation:

If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.

Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.
