Mutagens are chemical and physical agents that induce mutations in DNA (see Concept 17.5 ). How does reduced ozone concentration in the atmosphere increase the likelihood of mutations in various organisms?

Answers

Answer 1

Reduced ozone levels raise the amount of UV light that reaches the earth and its inhabitants. Mutations are caused by UV radiation by disrupting thymine dimers in DNA.

as ambient temperature decreases, metabolic rate in an ectotherm decreases to maintain body temperature

Answers

Metabolism is slow and heat is generated. Endotherms use metabolic heat to maintain a stable body temperature, but not exogenous heat.

An animal's "baseline" metabolic rate  is measured as the basal metabolic rate (BMR) for endotherms or as the standard metabolic rate (SMR) for exotherms. Among endotherms, smaller animals tend to have higher  basal metabolic rates per gram than larger animals (“hotter” metabolism). The same applies to external temperature, although groups cannot be compared. Your metabolic rate depends on your activity level. A more active animal has a higher metabolic rate than a less active animal. Some animals go into a state of lethargy where their metabolism slows down. Winter hibernation and  summer hibernation are forms of lethargy.

Ectotherms, however, lower their metabolic rate as the outside temperature drops in order to preserve body temperature.

Can the dorsal lip of the blastopore induce cells in another part of the amphibian embryo to change their developmental fate?

Answers

When transplanted, the dorsal lip of the blastopore—the region destined to give rise to the dorsal mesoderm—not only did not alter fate, but also caused the host cells around it to do so.

Hans Spemann and his graduate student Hilde Mangold carried out the crucial experiments in 1924. They discovered that when transplanted to an ectopic host site, one area of the late blastula and early gastrula functioned in an exceptional manner. When transplanted, the dorsal lip of the blastopore—the region destined to give rise to the dorsal mesoderm—not only did not alter fate, but also caused the host cells around it to do so. The dorsal lip transplant dramatically altered the fate of the embryo, inducing a brand-new developmental axis.

Answer:

Explanation:

A tree dies and decomposes over time is an example of entropy. Therefore, option (D) is correct.

Entropy is a concept in thermodynamics that refers to the measure of the disorder or randomness in a system. In the context of the options provided, the process of a tree dying and decomposing over time is an example of entropy. As the tree decomposes, its complex organic matter breaks down into simpler compounds, and the overall system becomes more disordered and randomized.

Entropy tends to increase over time in natural processes, leading to a more disordered and less organized state. In the case of the decomposing tree, the once structured and organized tree gradually breaks down, and its components disperse and mix with the environment, increasing the overall disorder in the system. This example illustrates the principle of increasing entropy observed in various natural processes. Therefore, option (D) is correct.
