the correct answer is A- Reproductive isolation occurred through behavioral isolation
A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.
In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
The Correct Answer Is "A - Solar Day"
Hello. This question is incomplete. The full question is:
In 10th grade , Natalie fits the societal ideal of a slender body type . She is most likely a(n) :
A) late-maturer.
B) average-maturer.
C) prepubescent.
D) early-maturer.
Answer:
D) early-maturer.
Explanation:
If Natalie is in 10th grade, it means she is around 15-16 years old. This is an age when the body is being modeled after the molds of an adult body. However, children's characteristics should still be present at this age.
This is not what is happening to Natalie, since at this age she has a body that fits society's standards for a slim body. These standards of beauty in society are aimed at adult bodies, Natalie is not an adult, which shows that she is a person with early maturity.
Answer:
b. 10% of the plant's energy.
Explanation:
In an ecosystem, there are various trophic levels, which form the part of the food chain. Producer like plants forms the first trophic level as they synthesize their own food via photosynthesis.
Hope it helps! ^_^
Answer and Explanation:
Example of a food-web:
(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.
1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.
The next links are the consumers:
2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.
3) Krills are the secondary consumers and feed on protozoans.
4) Some species of cephalopods feed on krill, among other species.
5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.
6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
