However, features of Marfan syndrome and related disorders can appear at any age. Some people have many features at birth or as young children. Other people develop features, including aortic enlargement, as teens or even as adults. Some features are progressive, meaning they can get worse as people age.
Answer: A- Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription.
Explanation:
Obsessive-compulsive disorder is
an anxiety disorder in which an individual have persistent unwanted thoughts or
obsessions that gives them the urge to do something repeatedly. People with obsessive-compulsive
disorder find it difficult to stop the compulsive acts or to keep their focus
off the obsessions and an attempt to stop it can lead to depression and severe
anxiety. For the question given above, George is likely to experience severe
anxiety if he tries to stop his compulsive behaviors.
Answer:
One of water’s important properties is that it is composed of polar molecules. The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen. Thus, it is more likely that a shared electron would be found near the oxygen nucleus than the hydrogen nucleus. Since water is a nonlinear, or bent, molecule, the difference in electronegativities between the oxygen and hydrogen atoms generates the partial negative charge near the oxygen and partial positive charges near both hydrogens.
Explanation:
As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids. A polar substance that interacts readily with or dissolves in water is referred to as hydrophilic (hydro- = “water”; -philic = “loving”). In contrast, nonpolar molecules, such as oils and fats, do not interact well with water, as shown in. These molecules separate from it rather than dissolve in it, as we see in salad dressings containing oil and vinegar (an acidic water solution). These nonpolar compounds are called hydrophobic (hydro- = “water”; -phobic = “fearing”).
Answer:
biotic: preditors, soil bacteria content, plant life, algae
abiotic: temp, soil pH, wind, water
biotic menas alive abiotic means not alive
