Why are monarch butterflies poisonous?

Biology

Brut [27]3 years ago

Answer:

Explanation:

The milkweed plant also has high concentrations of cardiac glycosides in its sap. ... In addition, the caterpillar of the monarch butterfly dines exclusively on the sap of the milkweed plant, rendering both the caterpillar and butterfly mildly toxic as well.

Predators know that monarch butterflies are poisonous because of their bright coloration, which acts as a warning that they are poisonous.

This coloration warns potential predators that the animal contains poisonous chemicals. Warning coloration may work particularly well in adult butterflies because the hard body and wings allows a predator to bite the adult, taste the poison, and release the butterfly without killing it.

Monarchs eat a plant called milkweed, which is why they are sometimes called “milkweed butterflies.” Milkweed contains toxins that are not poisonous to Monarchs but are poisonous to other living things. These toxins that are a regular part of the Monarch butterfly's diet make them poisonous to predators.
...... Predators that taste their food will spit out a Monarch Butterfly. If they have the ability to vomit, after swallowing a Monarch predators will usually do so...... This coloration warns potential predators that the animal contains poisonous chemicals. Warning coloration may work particularly well in adult butterflies because the hard body and wings allows a predator to bite the adult, taste the poison, and release the butterfly without killing it.

Genetic drift occurs when people move into or out of a population. <br> a. True <br> b. False
Ede4ka [16]
The statement would be considered to be B. False, because genetic drift occurs when different genotypes in smaller populations have a chance of disappearance. This is due to the species either dying off or not reproducing with others, so the genotype doesn't spread to offspring, because the species didn't have offspring.

How does archbishop usshers work compare to that of james hutton
Nataly_w [17]

<span>James Ussher was a creative scholar, a church leader and became famous for his genuine letters of the church. He is the Archbishop of all Ireland and majorly impacted Reformation theology.  He is best known for his chronology research that concluded Adam was created in 4004 B.C. In reality, Ussher was a first-class scholar very involved in scholarly research. He regularly interacted with “the most learned men of the day” to intellectually savor their ideas. He was also “a real connoisseur of books,” and there was scarcely a book in any British library that he was unfamiliar with. While James Hutton is known as the Father of Modern Geology, Hutton is a Scottish Geologist and a naturalist who originated the concept of earth’s crust during geological history, which explains the features of the Earth's crust by means of natural processes over geologic time.  Hutton had formulated controversial theories of the origin of the earth and of atmospheric changes known as 'uniformitarian’s'. This paved the way for modern geological science.</span>
