Refer to Animation: Countercurrent Multiplication. What would you predict to be the effect on an animal species of having longer

attashe74 [19]

Answer:

The correct answers is: I would predict that animals with longer loops of Henle would be able to concentrate their urine more than animals with shorter loops, and thus they would more likely survive in desserts and other dry areas.

Explanation:

The Loop of Henle is a tubule system that connects the proximal convoluted tubule to the distal convoluted tubule in a nephron, the functional and structural unit of the kidney. Its primary job is to establish a concentration gradient in the kidney's medulla by creating a high urea concentration deep in the medulla using a countercurrent multiplier system that uses electrolyte pumps. Through this mechanism, water is reabsorbed to concentrate the urine and impede dehydration.

The length of the loops of Henle is of great importance for the countercurrent multiplier system - the longer they are, the more concentrated the urine can get. Therefore, animals with longer loops can survive better in habitats where there is not much water around.

Black fur (B) is dominant to white fur (b) in guinea pigs. An F1 cross was conducted and resulted in 100% heterozygous guinea pi

Lemur [1.5K]

Answer:

D. 1 BB : 2 Bb : 1 bb

Explanation:

This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.

If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:

Bb = B and b

Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:

1 BB : 2 Bb : 1 bb

BB and Bb = black fur guinea pigs

bb = white fur guinea pigs

Why is it important to be aware of the observable signs of an eruption

Oksana_A [137]

Monitoring water changes can provide clues about the activity of a volcano. A sudden change could predict a volcanic eruption. Hydrologists also identify the paths that water takes as it flows down a volcano's side. Understanding how water flows can help us understand how lava might flow.
