Yes that is true. The gray matter of the cerebrum is the area of the brain where nerve cell bodies make connections, called synapses, that control brain activity.
White matter, on the other hand, is mostly the axons of neurons. The pale fatty insulator of axons, myelin, is mainly responsible for their whitish appearance on gross examination.
Answer:
All carbohydrates have the general formula Cn(H2O)n
Explanation:
The basic unit of carbohydrates-monosaccharides have the formula C
nH
2nO
n while the basic general formula of carbohydrates is Cm(H2O)n .
Monosaccharides are basic units (components) of carbohydrates. Those are simple sugars such as glucose, fructose, galactose. Two monosaccharides can join together via glycosylic bond and make disaccharides. Some of the disaccharides are: sucrose (glucose + fructose), lactose (galactose + glucose), maltose (glucose + glucose).
Disaccharides can be broken down to monosaccharides by an enzyme called a disaccharidase.
Longer chains of monosaccharides form oligosaccharides (usually as glycolipids ) and polysaccharides (starch, glycogen,cellulose, chitin).
Carbohyrates are important biomolecules included in metabolism, energy storage, they are also structural components, have role in immune response, as coenzymes etc.
Answer:
The correct answer is "False".
Explanation:
Hydrogen bonding in DNA between Cytosine and Guanine is more stable that between Adenine and Thymine. This difference in stability is given by the number of hydrogen bonds that form the bindings among the nucleotides. Three hydrogen bonds are formed between Cytosine and Guanine, while only two hydrogen bonds are formed between Adenine and Thymine.
