St Luke Drawing the Virgin, a masterpiece by the Dutch painter
Rogier van der Weyden made in the 15th century, depicts St. Luke the
Evangelist sketching the Virgin Mary as she nurses the Child Jesus. The painting
is unusually rich in details, as the figures are inside an upper-class parlor
that leads toward a courtyard, river, town, and landscape – a scene not even
possible in movies. Despite a lot of that, the scene is perfectly balanced. Scholars
believe that the painter made the painting not only to depict the artist’s
adoration to the Madonna and a salute to St. Luke (patron saint of painters),
but also to boast his own skill in composition and design.
<span>The most expectant evolutionary feature would be longer necks. This will enable the tortoises to reach the higher grass. This <span>would occur through natural selection that would favor the extreme traits (alleles of long neck) of long necks in the population.</span></span>
<span>Using a genetic cross, we can look at the following
A = brown a = White, B = Tall, b = small
With the capital letters being the dominant allele
A a
B AB aB
b Ab ab
The allele we are looking for is Ab which as 1/4 chance
To work out how many are in 2/6 also (1/3)
we do 1/4 x 1/4 x 1/4 = 1/64</span>
Answer:
The statement that accurately compares and contrasts the red blood cell and the white blood cell is that both have the same copy of DNA, but different genes are expressed in the two cell types.
Explanation:
Red blood cells (RBC) and white blood cells (WBC) are two highly differentiated types of cells that come from the hematopoietic system and have different functions in the blood.
Compared to WBC , RBC cells lack a nucleus and have fewer organelles, and their function is to transport gases in the blood, unlike the former which are involved in the body's defence.
<em>Cell differentiation is based on gene expression of the genome, resulting in different types of proteins synthesized in each cell, which give them a different structure and function.
</em>
Both <u>WBC and RBC have the same genome</u>, but different genes are expressed in each, giving them different morphological and functional characteristics.

Diarrhea can be caused by indigestion, a raw meal, or little bacterias found in almost anything we swallow, but if it doesn´t stop in a 12 hours period, it may be caused by some infection or a worse condition that need to be seen by a doctor, is this case, the nurse is concerned because Aidan is severely weakened, signal that is dehydrating very fast and that could cause him a worse condition such as hypotension, hypoglycemy or even losing consciouness.
