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.

Hermaphrodite, cellular respiration, invertebrate, medusae, metamorphosis, bilateral symmetry, coelomate, acoelomate1. an animal

givi [52]

Answer:

1. an animal without a body cavity acoelomate

2. condition in which the left side of an organism's body is a mirror image of the right side bilateral symmetry

3. a series of chemical reactions that break down sugars and produce energy cellular respiration

4. an animal with a fluid-filled body cavity that lies within the mesoderm coelomate

5. an animal that has both male and female reproductive organs Hermaphrodite

6. an animal without a backbone invertebrate

7. free-floating aquatic animals with a structure similar to a jellyfish medusae

8. the transformation of a larva to an adult; occurs only in animals having great differences in form between the larva and adult metamorphosis

Explanation:

Body cavity is a fluid-filled space inside a multicellular organism with the protective role. The coelom is the main body cavity, found in allmost all animals. Those that don't have coelom are called acoelomata. An example are Platyhelminthes.

Symmetry refers to the proportion of an animal: its reflection, rotation or scaling. The body symmetry of animals might be radial, bilateral, spherical or asymmetric.

Two major group of animals are Vertebrate and Invertebrate, with or without with backbone.

Hermaphrodite organisms are those that contain both, male and female reproductive organs, characteristic for invertebrates.

Which country's colonists maintained a profitable fur trade in North America

Tom [10]

Answer:

The North American fur trade was an industry and activity related to the acquisition, trade, exchange, and sale of animal furs in North America. Aboriginal peoples in Canada and Native Americans in the United States of various regions traded among themselves in the pre–Columbian Era. Europeans participated in the trade from the time of their arrival in the New World, extending the trade's reach to Europe. The French started trading in the 16th century, the English established trading posts on Hudson Bay in present-day Canada during the 17th century, while the Dutch had trade by the same time in New Netherland. North American fur trade was at its peak of economic importance in the 19th century, and involved the development of elaborate trade networks.

The fur trade became one of the main economic ventures in North America attracting competition among the French, British, Dutch, Spanish, and Russians. Indeed, in the early history of the United States, capitalizing on this trade, and removing the British stranglehold over it, was seen as a major economic objective. Many Native American societies across the continent came to depend on the fur trade as their primary source of income. By the mid-1800s changing fashions in Europe brought about a collapse in fur prices. The American Fur Company and some other companies failed. Many Native communities were plunged into long-term poverty and consequently lost much of the political influence they once had.
