Answers

Answer 1
Answer: The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of interstellar dust to the formation of planets.
Answer 2
Answer:

The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of interstellar dust to the formation of planets.

Interstellar dust is a significant component of the galaxy. It is produced in many various locations in the universe such as in the cooler outer layers of red giant stars where it is eventually blown off by the solar winds and it can also be produced in the expanding shell of gas residue from a supernova remnant. The central part of the interstellar dust is enclosed by ice and it is made up of either silicates or metals or at times a little of both.

Darwin hypothesized that there are definite steps to natural selection. Consider the model here. Use the Roman numerals (I - III) to guide you through the steps. Which is an accurate description of Darwin's hypothesized theory of natural selection? A) Sexual reproduction of bacteria cause variation. Some bacteria survive and some do not. Over time all of the bacteria should become extinct. B) In any population, variation exists. Some bacteria are resistant to antibiotics. Most bacteria die, but the bacteria that are resistant survive and reproduce. C) In a population of bacteria that are exposed to antibiotics, some bacteria change their genetic make-up and survive. The new genetic make-up is passed on to offspring. D) There is a change in the environment: an antibiotic is added. Some of the bacteria are capable of changing to the new environment. They survive and reproduce, passing along their favorable traits.

Which of the following are characteristics of generalist species?a. small habitat and restricted diet
b. large habitat and varied diet
c. restricted diet and physiological adaptations
d. behavioral and physiological adaptations

Answers

Answer;

B.large habitat and varied diet

Explanation;

-Behavioral and physiological adaptations are two characteristics of generalist species. A generalist species can adapt to different environments and resources. Omnivores animals are some example of generalists species. A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources.

b. Generalist species are not specialized, they do not have many adaptations. They can live in a large range of environments or habitats and eat a variety of foods.
