Answer:
2. This gives the worms two separate populations of offspring that have different chances of surviving. An added benefit of being a hermaphrodite is that if a worm never finds a mate, it can fertilize its own eggs and reproduce that way. Many hermaphrodites experience this benefit.
3. Surprisingly, earthworms have quite a few digestive organs in common with humans. Digestion starts in the mouth, which takes in soil. The food is then transferred to the pharynx, which swallows the dirt into the esophagus. Instead of a stomach, earthworms have a crop which stores food and connects to the gizzard.
Explanation:
4. Worm castings contain the worms' gut bacteria and mucus. These microbes and substances are very helpful to plants. Vermicompost has more nitrogen-fixing bacteria than conventional compost. Vermicompost helps make minerals in the surrounding soil available to plants more quickly.
5. Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
What types of factors should be investigated?
D. Both abiotic and biotic factors in their ecosystem
Abiotic factors are non-living parts of an environment, while Biotic factors are the living parts of an environment. That being said, you should investigate both when the population of jellyfish show a sharp decline, in order to find out the cause in the decline of jellyfish.
Answer:
There are less white mice in the third box because the bird has already been there. But it is harder for it to see the dark mouse so they are safer and more of them are left. In the second box the bird is holding a white mouse. But the first and second boxes have about the same numbers of mice because the bird already has one
Explanation:
Answer:
A. Tai
Explanation:
According to the given information, nucleus from the ear cells of the male "Tai" was inserted into the egg cell from a donor. The nucleus of the egg cell was removed before transferring the nucleus from Tai. Therefore, the egg cell contained the nucleus of the ear cell from "Tai". The embryo developed from this egg would have the nuclear DNA from Tai as the nuclear DNA from the egg donor was removed during enucleation. The embryo would be genetically similar to the male Afghan "Tai" who served as a donor of the nuclear DNA.
<h2>Answer:</h2>
<u>The climate, growing season and soil quality are abiotic factors which characterize a biome.</u>
<h3>Explanation:</h3>
Biome is defined as a community of living (plants and animals) components having same characteristics to help them live in the same environment.
Living components are known as biotic components and non living components are known as abiotic factors.
Most important abiotic factors climate which includes the temperature, pressure, precipitation, rain fall etc of that ecosystem.
While soil condition of that biome shows the fertility and determine the living factors of biome.
