Earthworms help farmers. Many farmers add them to their farmland because they help form rich soil to grow crops in.

Earthworms mix different layers of soil together by carrying humus from the surface down into the subsoil. Humus is a dark-colored substance made up of a variety of materials. Which two of the following are found in humus? NO LINKS OR WILL BE REPORTED ⚠

Answer:

7

Explanation:

The number of proton becomes 7 in nitrogen- 14 because there is one proton increase in the nucleus as a result of radioactive decay. There are 6 number of protons and 8 number of neutron in the nucleus of carbon-14 isotope. when the radioactive decay occurs, there is decrease occur in neutron number by removing one neutron and number of proton increases in the nucleus due to addition of one proton so that's we can say that the number of proton in nitrogen-14 is 7.

The next two major events that take place in mitosis are the alignment of chromosomes at the center of the cell and the subsequent separation of sister chromatids to opposite mitotic spindle poles. These two events occur in metaphase and anaphase, respectively.

Answer:

1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.

2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.

The scenario that would lead to the greatest increase in the rabbit population is increased food supply and decreased predators.

Predatory animals are animals that feed on other animals. They occupy the top of the food chain and are therefore found in smaller numbers. Predators are usually large, agile and adapted for hunting. A good predator is not known just by its size.

With this information, we can conclude that the scenario that would lead to the greatest increase in the rabbit population is increased food supply and decreased predators.

Answer:

All life can be classified into three domains: Bacteria, Archaea, and Eukarya. Organisms in the domain Eukarya keep their genetic material in a nucleus and include the plants, animals, fungi, and protists.

Answer:

it is a type of mixed inhibition referred to as 'non-competitive inhibition'

Explanation:

Mixed inhibition occurs when an inhibitor binds to the enzyme in a site different from the active site where the substrate binds (i.e., the allosteric site). The term 'mixed' is because this inhibition is a mixture of competitive inhibition, where the inhibitor competes with a substrate to bind to the enzyme, and uncompetitive inhibition, where the inhibitor binds only to the complex formed between the enzyme and its substrate. In competitive inhibition, the maximal velocity of the reaction (Vmax) does not change, whereas the apparent Km (i.e., the concentration of substrate which permits the enzyme to achieve half Vmax) increases. ​Moreover, in non-competitive inhibition, the Km does not change, whereas the Vmax decreases. Non-competitive inhibition is a special type of mixed inhibition where the apparent Vmax (V app-max) is reduced, while the Km of the enzyme is unaffected.

Answer:

True.

Explanation:

Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

Answer:

Terms in this set (217) Thinking about the surface of cells, which of these cells has the largest problems due to surface area limitations? Eukaryotic cells are 10-100 times the size of prokaryotic cells.

Answer:

False.

Explanation:

No, Cilia are not involved in the transfer of the genetic material from one bacterial cell to another. The pili are the structure which is responsible for the transfer of genetic material from one bacteria to another. This transfer can only occur for those types of bacteria that possess a special plasmid that is responsible for the formation of pilus which leads to the transfer of genetic material. If the special plasmid is not present so there will be no tranfer of genetic material from one bacteria to another.
