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<em> Loop of Henle</em> 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, <u><em>water is reabsorbed to concentrate the urine and impede dehydration</em></u>.

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

The scientists modified the genes that were turned on/off (expressed) in mice. What happened to the offspring of these mice?
daser333 [38]

The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.

Explanation:

Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.

The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as

The altered genes will be expressed in the resulting progeny of mice.

The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.

Photophores are:
Kobotan [32]

Answer:

B) cells or tissue that produce light

Explanation:

It wouldn't be A because photophores do not affect the color of other organisms.

It wouldn't be C because the cells produce light, they don't necessarily change color.

Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.
