Challenges of moving from an aquatic to a terrestrial environment You have the pleasure of observing wood frog tadpoles in a pon

d on campus. You see them make the transition from gilled larvae into adults with lungs. In order to make this amazing transformation from an entirely aquatic life to one that includes time on land, your tadpoles will face a series of obstacles, not unlike those that the first vertebrate inhabitants of land faced. Complete the following sentences to correctly examine those changes.
circulatory system Because of their large________ , ancestral amphibians likely faced challenges supporting themselves out of the aquatic environment.
cartilaginous bones feeding Although there was far_________ oxygen available to gills in air than in water, the delicate structure of gills couldn't be supported in the terrestrial environment.
excretory system The costs of locomotion on land and greater oxygen demand from enlarged muscles led to modifications of the heart and_________
body size
more These early amphibians could not venture too far away from water because______ was restricted to moist environments.

Answer:

body size

more

circulatory system

egg deposition

Explanation:

Because of their large <em>body size</em> , ancestral amphibians likely faced challenges supporting themselves out of the aquatic environment.

Although there was far <em>more</em> oxygen available to gills in air than in water, the delicate structure of gills couldn't be supported in the terrestrial environment.

The costs of locomotion on land and greater oxygen demand from enlarged muscles led to modifications of the heart and <em>circulatory system</em>

These early amphibians could not venture too far away from water because <em>egg deposition</em> was restricted to moist environments.

Membrane lipids in tissue samples obtained from different parts of the leg of a reindeer have different fatty acid compositions.
AnnZ [28]

Answer:

The presence of a larger proportion of unsaturated fatty acids in membranes imparts them fluidity at lower temperatures as required to maintain their normal functioning.

Explanation:

The proportion of unsaturated and saturated fatty acids in membranes regulates their fluidity. At lower temperatures, membranes become more rigid. To maintain their normal fluidity, the proportion of the unsaturated fatty acids in membranes is increased. The unsaturated fatty acids have double bonds in their hydrocarbon tails which in turn do not allow their tight packing and impart fluidity to the membrane core.

At higher temperatures, membranes become more fluid and therefore, the proportion of the unsaturated fatty acids is reduced. The tissues of reindeer at the body's extremities such as those near hooves are exposed to surroundings and thereby, lose heat and have lower temperatures. To maintain the fluidity of membranes, the cells of these tissues incorporate more of the unsaturated fatty acids in their membranes as compared to the tissues in the upper legs where the body temperature is relatively higher.
