It also allows scientists to accept the outcome of research without filtering data or information. Scientists use the scientific method to test hypotheses or solutions and to answer questions. The steps of the include making an observation, asking a question and formulating a hypothesis.
Answer:
In cystic fibrosis, there is an alteration in the chlorine channels of all cells, so all kinds of body secretions are affected.
Body fluids thicken at the intestinal level, forming a mucus that blocks the ducts that carry digestive enzymes from the pancreas to the intestine.
These enzymes are responsible for generating nutrients or proteins, vitamins and even fats are absorbed.
Explanation:
This intestinal factor results in malnutrition, growth impairment, hypovitaminosis, decay, anemia, capillary fragility, decline and fatigue.
These wings share a similar shape due to a process known as convergent evolution. The wings, in this case, are analogous structures that developed independently from one another (aka they do not share a recent common ancestor), but the organisms adapted to a common environment. Simply put, their similar problems lead to similar solutions.
Nucleotides help form the backbone of DNA and RNA.
Nucleotides are subunits that are linked to form nucleic acids. All nucleotides are composed of three parts: a five carbon sugar, a phosphate and a nitrogen - rich structure called a nitrogenous base.
It is the phosphate group that that makes the nucleotide so critical in DNA structure. By linking the phosphate of one nucleotide to carbon 3 of the sugar in the neighboring nucleotide, a DNA polymer is made. The repeating pattern of phosphate, sugar, then phosphate again is commonly referred to as the backbone of the DNA or RNA molecule.
Organic matter is added to basic soil to neutralize its base which improves its quality.
<h3>What is an organic matter for soil? </h3>
Manures are organic matter. These are the waste products of plants and animals that are used as sources of plant nutrients. After their decomposition, they release nutrients.
The practice of collecting and using wastes from animal, human and vegetable sources for the improvement of productivity of crops is as old as the practice of agriculture.
Plant nutrients in complex organic forms are present in the manure which is the organic matter in the plant and animal wastes. The synthetic chemicals that contain plant nutrients are called fertilizers.
Manures have low nutrient content per unit quantity and have a longer residual effects. They can work by improving soil's physical properties compared to fertilizer with high nutrient content.
Therefore, organic matter is added to basic soil to neutralize its base which improves its quality.
