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.
The letter I is just there. Blood type problems will usually have

and

= blood type A

and

= blood type B

would be blood type AB
<span>

would be blood type O.
</span>
So the answer would be B since B is the only option that the offspring would be only blood type B, which is the same as their parents.
The occipital lobe is responsible for vision. so Dane will most likely suffer vision loss
Although not specified, I am assuming that you want to identify the different variables and groups of this case. To answer this, the different typical factors that make up an experimental set up include: 1) dependent and 2) independent variables; 3) controlled variables; as well as the 4) control and 5) experimental group.
The dependent variable in this case is: the size of the population. While the independent variable is: the habitat space. Controlled variables in this experiment include: type and amount of food, cleanliness of the aquarium, and water temperature. The experimental group are simply the fish being observed. There are no controlled groups in this case depending on your definition. Controlled groups are usually the reference point or standard in experimental setups but this experiment wants to look at the differences of the goldfish with each other and not necessarily to a one particular goldfish and hence no controlled group.
The dependent variable is called as such because it is the one that changes depending on the factors given and is usually the one being observed. The independent variable is named as such because it remains the same throughout the experiment.
