The central element for all living things is carbon, which is why you might often hear the phrase "carbon-based" lifeforms. Another term is often "organic matter"
Answer:Magnetic forces are stronger closer to magnets. The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
Explanation:
Answer:
They tunnel through the soil, which allows air to enter.
Explanation:
Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.
They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.
Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.
Hope it help!
Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
A microscope is said to be parfocal if its lense is binocular and they can both be in focus.
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.
The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:
modifications in the function, shape or in the combination with other proteins.
Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.
Let's analyse what happens in each level of structure:
- In the case of the primary structure, which is the sequence of amino acids, the modification will give a non-functional protein that will not fold into the following structural level. So, there won't be new hair.
- For the secondary structure, a modification here can lead to a different folding. In other words, it can change from an α helix to a β pleated sheet or the other way round. This will give a different shape to the hair, like curly or straight.
- A modification in the tertiary structure modifies the interaction of the R groups in the protein, so the three-dimensional structure that this interaction gives will change, giving a different type of hair.
- Lastly, if we modify the quaternary structure, the protein won't interact with some proteins, but it may interact with others.
In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.
